-Installing GNU CC
-*****************
-
- Note most of this information is out of date and superseded by the
-online GCC install procedures `http://gcc.gnu.org/install/'. It is
-provided for historical reference only.
-
- Here is the procedure for installing GNU CC on a GNU or Unix system.
-See *Note VMS Install::, for VMS systems. In this section we assume you
-compile in the same directory that contains the source files; see *Note
-Other Dir::, to find out how to compile in a separate directory on Unix
-systems.
-
- You cannot install GNU C by itself on MSDOS; it will not compile
-under any MSDOS compiler except itself. You need to get the complete
-compilation package DJGPP, which includes binaries as well as sources,
-and includes all the necessary compilation tools and libraries.
-
- 1. If you have built GNU CC previously in the same directory for a
- different target machine, do `make distclean' to delete all files
- that might be invalid. One of the files this deletes is
- `Makefile'; if `make distclean' complains that `Makefile' does not
- exist, it probably means that the directory is already suitably
- clean.
-
- 2. On a System V release 4 system, make sure `/usr/bin' precedes
- `/usr/ucb' in `PATH'. The `cc' command in `/usr/ucb' uses
- libraries which have bugs.
-
- 3. Make sure the Bison parser generator is installed. (This is
- unnecessary if the Bison output file `c-parse.c' is more recent
- than `c-parse.y',and you do not plan to change the `.y' file.)
-
- Bison versions older than Sept 8, 1988 will produce incorrect
- output for `c-parse.c'.
-
- 4. If you have chosen a configuration for GNU CC which requires other
- GNU tools (such as GAS or the GNU linker) instead of the standard
- system tools, install the required tools in the build directory
- under the names `as', `ld' or whatever is appropriate. This will
- enable the compiler to find the proper tools for compilation of
- the program `enquire'.
-
- Alternatively, you can do subsequent compilation using a value of
- the `PATH' environment variable such that the necessary GNU tools
- come before the standard system tools.
-
- 5. Specify the host, build and target machine configurations. You do
- this when you run the `configure' script.
-
- The "build" machine is the system which you are using, the "host"
- machine is the system where you want to run the resulting compiler
- (normally the build machine), and the "target" machine is the
- system for which you want the compiler to generate code.
-
- If you are building a compiler to produce code for the machine it
- runs on (a native compiler), you normally do not need to specify
- any operands to `configure'; it will try to guess the type of
- machine you are on and use that as the build, host and target
- machines. So you don't need to specify a configuration when
- building a native compiler unless `configure' cannot figure out
- what your configuration is or guesses wrong.
-
- In those cases, specify the build machine's "configuration name"
- with the `--host' option; the host and target will default to be
- the same as the host machine. (If you are building a
- cross-compiler, see *Note Cross-Compiler::.)
-
- Here is an example:
-
- ./configure --host=sparc-sun-sunos4.1
-
- A configuration name may be canonical or it may be more or less
- abbreviated.
-
- A canonical configuration name has three parts, separated by
- dashes. It looks like this: `CPU-COMPANY-SYSTEM'. (The three
- parts may themselves contain dashes; `configure' can figure out
- which dashes serve which purpose.) For example,
- `m68k-sun-sunos4.1' specifies a Sun 3.
-
- You can also replace parts of the configuration by nicknames or
- aliases. For example, `sun3' stands for `m68k-sun', so
- `sun3-sunos4.1' is another way to specify a Sun 3. You can also
- use simply `sun3-sunos', since the version of SunOS is assumed by
- default to be version 4.
-
- You can specify a version number after any of the system types,
- and some of the CPU types. In most cases, the version is
- irrelevant, and will be ignored. So you might as well specify the
- version if you know it.
-
- See *Note Configurations::, for a list of supported configuration
- names and notes on many of the configurations. You should check
- the notes in that section before proceeding any further with the
- installation of GNU CC.
-
- 6. When running `configure', you may also need to specify certain
- additional options that describe variant hardware and software
- configurations. These are `--with-gnu-as', `--with-gnu-ld',
- `--with-stabs' and `--nfp'.
-
- `--with-gnu-as'
- If you will use GNU CC with the GNU assembler (GAS), you
- should declare this by using the `--with-gnu-as' option when
- you run `configure'.
-
- Using this option does not install GAS. It only modifies the
- output of GNU CC to work with GAS. Building and installing
- GAS is up to you.
-
- Conversely, if you *do not* wish to use GAS and do not specify
- `--with-gnu-as' when building GNU CC, it is up to you to make
- sure that GAS is not installed. GNU CC searches for a
- program named `as' in various directories; if the program it
- finds is GAS, then it runs GAS. If you are not sure where
- GNU CC finds the assembler it is using, try specifying `-v'
- when you run it.
-
- The systems where it makes a difference whether you use GAS
- are
- `hppa1.0-ANY-ANY', `hppa1.1-ANY-ANY', `i386-ANY-sysv',
- `i386-ANY-isc',
- `i860-ANY-bsd', `m68k-bull-sysv',
- `m68k-hp-hpux', `m68k-sony-bsd',
- `m68k-altos-sysv', `m68000-hp-hpux',
- `m68000-att-sysv', `ANY-lynx-lynxos', and `mips-ANY'). On
- any other system, `--with-gnu-as' has no effect.
-
- On the systems listed above (except for the HP-PA, for ISC on
- the 386, and for `mips-sgi-irix5.*'), if you use GAS, you
- should also use the GNU linker (and specify `--with-gnu-ld').
-
- `--with-gnu-ld'
- Specify the option `--with-gnu-ld' if you plan to use the GNU
- linker with GNU CC.
-
- This option does not cause the GNU linker to be installed; it
- just modifies the behavior of GNU CC to work with the GNU
- linker.
-
- `--with-stabs'
- On MIPS based systems and on Alphas, you must specify whether
- you want GNU CC to create the normal ECOFF debugging format,
- or to use BSD-style stabs passed through the ECOFF symbol
- table. The normal ECOFF debug format cannot fully handle
- languages other than C. BSD stabs format can handle other
- languages, but it only works with the GNU debugger GDB.
-
- Normally, GNU CC uses the ECOFF debugging format by default;
- if you prefer BSD stabs, specify `--with-stabs' when you
- configure GNU CC.
-
- No matter which default you choose when you configure GNU CC,
- the user can use the `-gcoff' and `-gstabs+' options to
- specify explicitly the debug format for a particular
- compilation.
-
- `--with-stabs' is meaningful on the ISC system on the 386,
- also, if `--with-gas' is used. It selects use of stabs
- debugging information embedded in COFF output. This kind of
- debugging information supports C++ well; ordinary COFF
- debugging information does not.
-
- `--with-stabs' is also meaningful on 386 systems running
- SVR4. It selects use of stabs debugging information embedded
- in ELF output. The C++ compiler currently (2.6.0) does not
- support the DWARF debugging information normally used on 386
- SVR4 platforms; stabs provide a workable alternative. This
- requires gas and gdb, as the normal SVR4 tools can not
- generate or interpret stabs.
-
- `--nfp'
- On certain systems, you must specify whether the machine has
- a floating point unit. These systems include
- `m68k-sun-sunosN' and `m68k-isi-bsd'. On any other system,
- `--nfp' currently has no effect, though perhaps there are
- other systems where it could usefully make a difference.
-
- `--enable-haifa'
- `--disable-haifa'
- Use `--enable-haifa' to enable use of an experimental
- instruction scheduler (from IBM Haifa). This may or may not
- produce better code. Some targets on which it is known to be
- a win enable it by default; use `--disable-haifa' to disable
- it in these cases. `configure' will print out whether the
- Haifa scheduler is enabled when it is run.
-
- `--enable-threads=TYPE'
- Certain systems, notably Linux-based GNU systems, can't be
- relied on to supply a threads facility for the Objective C
- runtime and so will default to single-threaded runtime. They
- may, however, have a library threads implementation
- available, in which case threads can be enabled with this
- option by supplying a suitable TYPE, probably `posix'. The
- possibilities for TYPE are `single', `posix', `win32',
- `solaris', `irix' and `mach'.
-
- `--enable-checking'
- When you specify this option, the compiler is built to
- perform checking of tree node types when referencing fields
- of that node. This does not change the generated code, but
- adds error checking within the compiler. This will slow down
- the compiler and may only work properly if you are building
- the compiler with GNU C.
-
- The `configure' script searches subdirectories of the source
- directory for other compilers that are to be integrated into
- GNU CC. The GNU compiler for C++, called G++ is in a
- subdirectory named `cp'. `configure' inserts rules into
- `Makefile' to build all of those compilers.
-
- Here we spell out what files will be set up by `configure'.
- Normally you need not be concerned with these files.
-
- * A file named `config.h' is created that contains a
- `#include' of the top-level config file for the machine
- you will run the compiler on (*note The Configuration
- File: (gcc.info)Config.). This file is responsible for
- defining information about the host machine. It
- includes `tm.h'.
-
- The top-level config file is located in the subdirectory
- `config'. Its name is always `xm-SOMETHING.h'; usually
- `xm-MACHINE.h', but there are some exceptions.
-
- If your system does not support symbolic links, you
- might want to set up `config.h' to contain a `#include'
- command which refers to the appropriate file.
-
- * A file named `tconfig.h' is created which includes the
- top-level config file for your target machine. This is
- used for compiling certain programs to run on that
- machine.
-
- * A file named `tm.h' is created which includes the
- machine-description macro file for your target machine.
- It should be in the subdirectory `config' and its name
- is often `MACHINE.h'.
-
- `--enable-nls'
- `--disable-nls'
- The `--enable-nls' option enables Native Language Support
- (NLS), which lets GCC output diagnostics in languages other
- than American English. Native Language Support is enabled by
- default if not doing a canadian cross build. The
- `--disable-nls' option disables NLS.
-
- `--with-included-gettext'
- If NLS is enbled, the `--with-included-gettext' option causes
- the build procedure to prefer its copy of GNU `gettext'. This
- is the default. If you want the GCC build procedure to prefer
- the host's `gettext' libraries, use
- `--without-included-gettext'.
-
- `--with-catgets'
- If NLS is enabled, and if the host lacks `gettext' but has the
- inferior `catgets' interface, the GCC build procedure normally
- ignores `catgets' and instead uses GCC's copy of the GNU
- `gettext' library. The `--with-catgets' option causes the
- build procedure to use the host's `catgets' in this situation.
-
- `--enable-maintainer-mode'
- The build rules that regenerate the GCC master message catalog
- `gcc.pot' are normally disabled. This is because it can only
- be rebuilt if the complete source tree is present. If you
- have changed the sources and want to rebuild the catalog,
- configuring with `--enable-maintainer-mode' will enable this.
- Note that you need a special version of the `gettext' tools
- to do so.
-
- `--enable-win32-registry'
- `--enable-win32-registry=KEY'
- `--disable-win32-registry'
- The `--enable-win32-registry' option enables Windows-hosted
- GCC to look up installations paths in the registry using the
- following key:
-
- `HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\<KEY>'
-
- <KEY> defaults to GCC version number, and can be overridden
- by the `--enable-win32-registry=KEY' option. Vendors and
- distributors who use custom installers are encouraged to
- provide a different key, perhaps one comprised of vendor name
- and GCC version number, to avoid conflict with existing
- installations. This feature is enabled by default, and can be
- disabled by `--disable-win32-registry' option. This option
- has no effect on the other hosts.
-
- 7. In certain cases, you should specify certain other options when
- you run `configure'.
-
- * The standard directory for installing GNU CC is
- `/usr/local/lib'. If you want to install its files somewhere
- else, specify `--prefix=DIR' when you run `configure'. Here
- DIR is a directory name to use instead of `/usr/local' for
- all purposes with one exception: the directory
- `/usr/local/include' is searched for header files no matter
- where you install the compiler. To override this name, use
- the `--with-local-prefix' option below. The directory you
- specify need not exist, but its parent directory must exist.
-
- * Specify `--with-local-prefix=DIR' if you want the compiler to
- search directory `DIR/include' for locally installed header
- files *instead* of `/usr/local/include'.
-
- You should specify `--with-local-prefix' *only* if your site
- has a different convention (not `/usr/local') for where to put
- site-specific files.
-
- The default value for `--with-local-prefix' is `/usr/local'
- regardless of the value of `--prefix'. Specifying `--prefix'
- has no effect on which directory GNU CC searches for local
- header files. This may seem counterintuitive, but actually
- it is logical.
-
- The purpose of `--prefix' is to specify where to *install GNU
- CC*. The local header files in `/usr/local/include'--if you
- put any in that directory--are not part of GNU CC. They are
- part of other programs--perhaps many others. (GNU CC
- installs its own header files in another directory which is
- based on the `--prefix' value.)
-
- *Do not* specify `/usr' as the `--with-local-prefix'! The
- directory you use for `--with-local-prefix' *must not* contain
- any of the system's standard header files. If it did contain
- them, certain programs would be miscompiled (including GNU
- Emacs, on certain targets), because this would override and
- nullify the header file corrections made by the `fixincludes'
- script.
-
- Indications are that people who use this option use it based
- on mistaken ideas of what it is for. People use it as if it
- specified where to install part of GNU CC. Perhaps they make
- this assumption because installing GNU CC creates the
- directory.
-
- 8. Build the compiler. Just type `make LANGUAGES=c' in the compiler
- directory.
-
- `LANGUAGES=c' specifies that only the C compiler should be
- compiled. The makefile normally builds compilers for all the
- supported languages; currently, C, C++, Objective C, Java,
- FORTRAN, and CHILL. However, C is the only language that is sure
- to work when you build with other non-GNU C compilers. In
- addition, building anything but C at this stage is a waste of time.
-
- In general, you can specify the languages to build by typing the
- argument `LANGUAGES="LIST"', where LIST is one or more words from
- the list `c', `c++', `objective-c', `java', `f77', and `CHILL'.
- If you have any additional GNU compilers as subdirectories of the
- GNU CC source directory, you may also specify their names in this
- list.
-
- Ignore any warnings you may see about "statement not reached" in
- `insn-emit.c'; they are normal. Also, warnings about "unknown
- escape sequence" are normal in `genopinit.c' and perhaps some
- other files. Likewise, you should ignore warnings about "constant
- is so large that it is unsigned" in `insn-emit.c' and
- `insn-recog.c', and a warning about a comparison always being zero
- in `enquire.o'. Any other compilation errors may represent bugs in
- the port to your machine or operating system, and should be
- investigated and reported.
-
- Some compilers fail to compile GNU CC because they have bugs or
- limitations. For example, the Microsoft compiler is said to run
- out of macro space. Some Ultrix compilers run out of expression
- space; then you need to break up the statement where the problem
- happens.
-
- 9. If you are building a cross-compiler, stop here. *Note
- Cross-Compiler::.
-
- 10. Move the first-stage object files and executables into a
- subdirectory with this command:
-
- make stage1
-
- The files are moved into a subdirectory named `stage1'. Once
- installation is complete, you may wish to delete these files with
- `rm -r stage1'.
-
- 11. If you have chosen a configuration for GNU CC which requires other
- GNU tools (such as GAS or the GNU linker) instead of the standard
- system tools, install the required tools in the `stage1'
- subdirectory under the names `as', `ld' or whatever is
- appropriate. This will enable the stage 1 compiler to find the
- proper tools in the following stage.
-
- Alternatively, you can do subsequent compilation using a value of
- the `PATH' environment variable such that the necessary GNU tools
- come before the standard system tools.
-
- 12. Recompile the compiler with itself, with this command:
-
- make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"
-
- This is called making the stage 2 compiler.
-
- The command shown above builds compilers for all the supported
- languages. If you don't want them all, you can specify the
- languages to build by typing the argument `LANGUAGES="LIST"'. LIST
- should contain one or more words from the list `c', `c++',
- `objective-c', and `proto'. Separate the words with spaces.
- `proto' stands for the programs `protoize' and `unprotoize'; they
- are not a separate language, but you use `LANGUAGES' to enable or
- disable their installation.
-
- If you are going to build the stage 3 compiler, then you might
- want to build only the C language in stage 2.
-
- Once you have built the stage 2 compiler, if you are short of disk
- space, you can delete the subdirectory `stage1'.
-
- On a 68000 or 68020 system lacking floating point hardware, unless
- you have selected a `tm.h' file that expects by default that there
- is no such hardware, do this instead:
-
- make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2 -msoft-float"
-
- 13. If you wish to test the compiler by compiling it with itself one
- more time, install any other necessary GNU tools (such as GAS or
- the GNU linker) in the `stage2' subdirectory as you did in the
- `stage1' subdirectory, then do this:
-
- make stage2
- make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"
-
- This is called making the stage 3 compiler. Aside from the `-B'
- option, the compiler options should be the same as when you made
- the stage 2 compiler. But the `LANGUAGES' option need not be the
- same. The command shown above builds compilers for all the
- supported languages; if you don't want them all, you can specify
- the languages to build by typing the argument `LANGUAGES="LIST"',
- as described above.
-
- If you do not have to install any additional GNU tools, you may
- use the command
-
- make bootstrap LANGUAGES=LANGUAGE-LIST BOOT_CFLAGS=OPTION-LIST
-
- instead of making `stage1', `stage2', and performing the two
- compiler builds.
-
- 14. Compare the latest object files with the stage 2 object files--they
- ought to be identical, aside from time stamps (if any).
-
- On some systems, meaningful comparison of object files is
- impossible; they always appear "different." This is currently
- true on Solaris and some systems that use ELF object file format.
- On some versions of Irix on SGI machines and DEC Unix (OSF/1) on
- Alpha systems, you will not be able to compare the files without
- specifying `-save-temps'; see the description of individual
- systems above to see if you get comparison failures. You may have
- similar problems on other systems.
-
- Use this command to compare the files:
-
- make compare
-
- This will mention any object files that differ between stage 2 and
- stage 3. Any difference, no matter how innocuous, indicates that
- the stage 2 compiler has compiled GNU CC incorrectly, and is
- therefore a potentially serious bug which you should investigate
- and report.
-
- If your system does not put time stamps in the object files, then
- this is a faster way to compare them (using the Bourne shell):
-
- for file in *.o; do
- cmp $file stage2/$file
- done
-
- If you have built the compiler with the `-mno-mips-tfile' option on
- MIPS machines, you will not be able to compare the files.
-
- 15. Install the compiler driver, the compiler's passes and run-time
- support with `make install'. Use the same value for `CC',
- `CFLAGS' and `LANGUAGES' that you used when compiling the files
- that are being installed. One reason this is necessary is that
- some versions of Make have bugs and recompile files gratuitously
- when you do this step. If you use the same variable values, those
- files will be recompiled properly.
-
- For example, if you have built the stage 2 compiler, you can use
- the following command:
-
- make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES="LIST"
-
- This copies the files `cc1', `cpp' and `libgcc.a' to files `cc1',
- `cpp' and `libgcc.a' in the directory
- `/usr/local/lib/gcc-lib/TARGET/VERSION', which is where the
- compiler driver program looks for them. Here TARGET is the
- canonicalized form of target machine type specified when you ran
- `configure', and VERSION is the version number of GNU CC. This
- naming scheme permits various versions and/or cross-compilers to
- coexist. It also copies the executables for compilers for other
- languages (e.g., `cc1plus' for C++) to the same directory.
-
- This also copies the driver program `xgcc' into
- `/usr/local/bin/gcc', so that it appears in typical execution
- search paths. It also copies `gcc.1' into `/usr/local/man/man1'
- and info pages into `/usr/local/info'.
-
- On some systems, this command causes recompilation of some files.
- This is usually due to bugs in `make'. You should either ignore
- this problem, or use GNU Make.
-
- *Warning: there is a bug in `alloca' in the Sun library. To avoid
- this bug, be sure to install the executables of GNU CC that were
- compiled by GNU CC. (That is, the executables from stage 2 or 3,
- not stage 1.) They use `alloca' as a built-in function and never
- the one in the library.*
-
- (It is usually better to install GNU CC executables from stage 2
- or 3, since they usually run faster than the ones compiled with
- some other compiler.)
-
- 16. If you're going to use C++, you need to install the C++ runtime
- library. This includes all I/O functionality, special class
- libraries, etc.
-
- The standard C++ runtime library for GNU CC is called `libstdc++'.
- An obsolescent library `libg++' may also be available, but it's
- necessary only for older software that hasn't been converted yet;
- if you don't know whether you need `libg++' then you probably don't
- need it.
-
- Here's one way to build and install `libstdc++' for GNU CC:
-
- * Build and install GNU CC, so that invoking `gcc' obtains the
- GNU CC that was just built.
-
- * Obtain a copy of a compatible `libstdc++' distribution. For
- example, the `libstdc++-2.8.0.tar.gz' distribution should be
- compatible with GCC 2.8.0. GCC distributors normally
- distribute `libstdc++' as well.
-
- * Set the `CXX' environment variable to `gcc' while running the
- `libstdc++' distribution's `configure' command. Use the same
- `configure' options that you used when you invoked GCC's
- `configure' command.
-
- * Invoke `make' to build the C++ runtime.
-
- * Invoke `make install' to install the C++ runtime.
-
- To summarize, after building and installing GNU CC, invoke the
- following shell commands in the topmost directory of the C++
- library distribution. For CONFIGURE-OPTIONS, use the same options
- that you used to configure GNU CC.
-
- $ CXX=gcc ./configure CONFIGURE-OPTIONS
- $ make
- $ make install
-
- 17. GNU CC includes a runtime library for Objective-C because it is an
- integral part of the language. You can find the files associated
- with the library in the subdirectory `objc'. The GNU Objective-C
- Runtime Library requires header files for the target's C library in
- order to be compiled,and also requires the header files for the
- target's thread library if you want thread support. *Note
- Cross-Compilers and Header Files: Cross Headers, for discussion
- about header files issues for cross-compilation.
-
- When you run `configure', it picks the appropriate Objective-C
- thread implementation file for the target platform. In some
- situations, you may wish to choose a different back-end as some
- platforms support multiple thread implementations or you may wish
- to disable thread support completely. You do this by specifying a
- value for the OBJC_THREAD_FILE makefile variable on the command
- line when you run make, for example:
-
- make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2" OBJC_THREAD_FILE=thr-single
-
- Below is a list of the currently available back-ends.
-
- * thr-single Disable thread support, should work for all
- platforms.
-
- * thr-decosf1 DEC OSF/1 thread support.
-
- * thr-irix SGI IRIX thread support.
-
- * thr-mach Generic MACH thread support, known to work on
- NEXTSTEP.
-
- * thr-os2 IBM OS/2 thread support.
-
- * thr-posix Generix POSIX thread support.
-
- * thr-pthreads PCThreads on Linux-based GNU systems.
-
- * thr-solaris SUN Solaris thread support.
-
- * thr-win32 Microsoft Win32 API thread support.
-
-Files Created by `configure'
-============================
-
- Here we spell out what files will be set up by `configure'. Normally
-you need not be concerned with these files.
-
- * A file named `config.h' is created that contains a `#include' of
- the top-level config file for the machine you will run the compiler
- on (*note The Configuration File: (gcc.info)Config.). This file
- is responsible for defining information about the host machine.
- It includes `tm.h'.
-
- The top-level config file is located in the subdirectory `config'.
- Its name is always `xm-SOMETHING.h'; usually `xm-MACHINE.h', but
- there are some exceptions.
-
- If your system does not support symbolic links, you might want to
- set up `config.h' to contain a `#include' command which refers to
- the appropriate file.
-
- * A file named `tconfig.h' is created which includes the top-level
- config file for your target machine. This is used for compiling
- certain programs to run on that machine.
-
- * A file named `tm.h' is created which includes the
- machine-description macro file for your target machine. It should
- be in the subdirectory `config' and its name is often `MACHINE.h'.
-
- * The command file `configure' also constructs the file `Makefile'
- by adding some text to the template file `Makefile.in'. The
- additional text comes from files in the `config' directory, named
- `t-TARGET' and `x-HOST'. If these files do not exist, it means
- nothing needs to be added for a given target or host.
-
-Configurations Supported by GNU CC
-==================================
-
- Here are the possible CPU types:
-
- 1750a, a29k, alpha, arm, avr, cN, clipper, dsp16xx, elxsi, fr30,
- h8300, hppa1.0, hppa1.1, i370, i386, i486, i586, i686, i786, i860,
- i960, m32r, m68000, m68k, m6811, m6812, m88k, mcore, mips, mipsel,
- mips64, mips64el, mn10200, mn10300, ns32k, pdp11, powerpc,
- powerpcle, romp, rs6000, sh, sparc, sparclite, sparc64, v850, vax,
- we32k.
-
- Here are the recognized company names. As you can see, customary
-abbreviations are used rather than the longer official names.
-
- acorn, alliant, altos, apollo, apple, att, bull, cbm, convergent,
- convex, crds, dec, dg, dolphin, elxsi, encore, harris, hitachi,
- hp, ibm, intergraph, isi, mips, motorola, ncr, next, ns, omron,
- plexus, sequent, sgi, sony, sun, tti, unicom, wrs.
-
- The company name is meaningful only to disambiguate when the rest of
-the information supplied is insufficient. You can omit it, writing
-just `CPU-SYSTEM', if it is not needed. For example, `vax-ultrix4.2'
-is equivalent to `vax-dec-ultrix4.2'.
-
- Here is a list of system types:
-
- 386bsd, aix, acis, amigaos, aos, aout, aux, bosx, bsd, clix, coff,
- ctix, cxux, dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms,
- genix, gnu, linux, linux-gnu, hiux, hpux, iris, irix, isc, luna,
- lynxos, mach, minix, msdos, mvs, netbsd, newsos, nindy, ns, osf,
- osfrose, ptx, riscix, riscos, rtu, sco, sim, solaris, sunos, sym,
- sysv, udi, ultrix, unicos, uniplus, unos, vms, vsta, vxworks,
- winnt, xenix.
-
-You can omit the system type; then `configure' guesses the operating
-system from the CPU and company.
-
- You can add a version number to the system type; this may or may not
-make a difference. For example, you can write `bsd4.3' or `bsd4.4' to
-distinguish versions of BSD. In practice, the version number is most
-needed for `sysv3' and `sysv4', which are often treated differently.
-
- `linux-gnu' is the canonical name for the GNU/Linux target; however
-GNU CC will also accept `linux'. The version of the kernel in use is
-not relevant on these systems. A suffix such as `libc1' or `aout'
-distinguishes major versions of the C library; all of the suffixed
-versions are obsolete.
-
- If you specify an impossible combination such as `i860-dg-vms', then
-you may get an error message from `configure', or it may ignore part of
-the information and do the best it can with the rest. `configure'
-always prints the canonical name for the alternative that it used. GNU
-CC does not support all possible alternatives.
-
- Often a particular model of machine has a name. Many machine names
-are recognized as aliases for CPU/company combinations. Thus, the
-machine name `sun3', mentioned above, is an alias for `m68k-sun'.
-Sometimes we accept a company name as a machine name, when the name is
-popularly used for a particular machine. Here is a table of the known
-machine names:
-
- 3300, 3b1, 3bN, 7300, altos3068, altos, apollo68, att-7300,
- balance, convex-cN, crds, decstation-3100, decstation, delta,
- encore, fx2800, gmicro, hp7NN, hp8NN, hp9k2NN, hp9k3NN, hp9k7NN,
- hp9k8NN, iris4d, iris, isi68, m3230, magnum, merlin, miniframe,
- mmax, news-3600, news800, news, next, pbd, pc532, pmax, powerpc,
- powerpcle, ps2, risc-news, rtpc, sun2, sun386i, sun386, sun3,
- sun4, symmetry, tower-32, tower.
-
-Remember that a machine name specifies both the cpu type and the company
-name. If you want to install your own homemade configuration files,
-you can use `local' as the company name to access them. If you use
-configuration `CPU-local', the configuration name without the cpu prefix
-is used to form the configuration file names.
-
- Thus, if you specify `m68k-local', configuration uses files
-`m68k.md', `local.h', `m68k.c', `xm-local.h', `t-local', and `x-local',
-all in the directory `config/m68k'.
-
- Here is a list of configurations that have special treatment or
-special things you must know:
-
-`1750a-*-*'
- MIL-STD-1750A processors.
-
- The MIL-STD-1750A cross configuration produces output for
- `as1750', an assembler/linker available under the GNU Public
- License for the 1750A. `as1750' can be obtained at
- `ftp://ftp.fta-berlin.de/pub/crossgcc/1750gals/'. A similarly
- licensed simulator for the 1750A is available from same address.
-
- You should ignore a fatal error during the building of libgcc
- (libgcc is not yet implemented for the 1750A.)
-
- The `as1750' assembler requires the file `ms1750.inc', which is
- found in the directory `config/1750a'.
-
- GNU CC produced the same sections as the Fairchild F9450 C
- Compiler, namely:
-
- `Normal'
- The program code section.
-
- `Static'
- The read/write (RAM) data section.
-
- `Konst'
- The read-only (ROM) constants section.
-
- `Init'
- Initialization section (code to copy KREL to SREL).
-
- The smallest addressable unit is 16 bits (BITS_PER_UNIT is 16).
- This means that type `char' is represented with a 16-bit word per
- character. The 1750A's "Load/Store Upper/Lower Byte" instructions
- are not used by GNU CC.
-
-`alpha-*-osf1'
- Systems using processors that implement the DEC Alpha architecture
- and are running the DEC Unix (OSF/1) operating system, for example
- the DEC Alpha AXP systems.CC.)
-
- GNU CC writes a `.verstamp' directive to the assembler output file
- unless it is built as a cross-compiler. It gets the version to
- use from the system header file `/usr/include/stamp.h'. If you
- install a new version of DEC Unix, you should rebuild GCC to pick
- up the new version stamp.
-
- Note that since the Alpha is a 64-bit architecture,
- cross-compilers from 32-bit machines will not generate code as
- efficient as that generated when the compiler is running on a
- 64-bit machine because many optimizations that depend on being
- able to represent a word on the target in an integral value on the
- host cannot be performed. Building cross-compilers on the Alpha
- for 32-bit machines has only been tested in a few cases and may
- not work properly.
-
- `make compare' may fail on old versions of DEC Unix unless you add
- `-save-temps' to `CFLAGS'. On these systems, the name of the
- assembler input file is stored in the object file, and that makes
- comparison fail if it differs between the `stage1' and `stage2'
- compilations. The option `-save-temps' forces a fixed name to be
- used for the assembler input file, instead of a randomly chosen
- name in `/tmp'. Do not add `-save-temps' unless the comparisons
- fail without that option. If you add `-save-temps', you will have
- to manually delete the `.i' and `.s' files after each series of
- compilations.
-
- GNU CC now supports both the native (ECOFF) debugging format used
- by DBX and GDB and an encapsulated STABS format for use only with
- GDB. See the discussion of the `--with-stabs' option of
- `configure' above for more information on these formats and how to
- select them.
-
- There is a bug in DEC's assembler that produces incorrect line
- numbers for ECOFF format when the `.align' directive is used. To
- work around this problem, GNU CC will not emit such alignment
- directives while writing ECOFF format debugging information even
- if optimization is being performed. Unfortunately, this has the
- very undesirable side-effect that code addresses when `-O' is
- specified are different depending on whether or not `-g' is also
- specified.
-
- To avoid this behavior, specify `-gstabs+' and use GDB instead of
- DBX. DEC is now aware of this problem with the assembler and
- hopes to provide a fix shortly.
-
-`arc-*-elf'
- Argonaut ARC processor. This configuration is intended for
- embedded systems.
-
-`arm-*-aout'
- Advanced RISC Machines ARM-family processors. These are often
- used in embedded applications. There are no standard Unix
- configurations. This configuration corresponds to the basic
- instruction sequences and will produce `a.out' format object
- modules.
-
- You may need to make a variant of the file `arm.h' for your
- particular configuration.
-
-`arm-*-elf'
- This configuration is intended for embedded systems.
-
-`arm-*-linux*aout'
- Any of the ARM-family processors running the Linux-based GNU
- system with the `a.out' binary format. This is an obsolete
- configuration.
-
-`arm-*-linux'
-`arm-*-linux-gnu'
-`arm-*-linux*oldld'
- Any of the ARM-family processors running the Linux-based GNU
- system with the `ELF' binary format. You must use version
- 2.9.1.0.22 or later of the GNU/Linux binutils, which you can
- download from `ftp://ftp.varesearch.com/pub/support/hjl/binutils/'.
-
- These two configurations differ only in the required version of GNU
- binutils. For binutils 2.9.1.0.x, use `arm-*-linux-gnuoldld'. For
- newer versions of binutils, use `arm-*-linux-gnu'.
-
-`arm-*-riscix'
- The ARM2 or ARM3 processor running RISC iX, Acorn's port of BSD
- Unix. If you are running a version of RISC iX prior to 1.2 then
- you must specify the version number during configuration. Note
- that the assembler shipped with RISC iX does not support stabs
- debugging information; a new version of the assembler, with stabs
- support included, is now available from Acorn and via ftp
- `ftp://ftp.acorn.com/pub/riscix/as+xterm.tar.Z'. To enable stabs
- debugging, pass `--with-gnu-as' to configure.
-
- You will need to install GNU `sed' before you can run configure.
-
-`a29k'
- AMD Am29k-family processors. These are normally used in embedded
- applications. There are no standard Unix configurations. This
- configuration corresponds to AMD's standard calling sequence and
- binary interface and is compatible with other 29k tools.
-
- You may need to make a variant of the file `a29k.h' for your
- particular configuration.
-
-`a29k-*-bsd'
- AMD Am29050 used in a system running a variant of BSD Unix.
-
-`avr'
- ATMEL AVR-family micro controllers. These are used in embedded
- applications. There are no standard Unix configurations.
- Supports following MCU's: - AT90S23xx - ATtiny22 - AT90S44xx -
- AT90S85xx - ATmega603/603L - ATmega103/103L
-
-`decstation-*'
- MIPS-based DECstations can support three different personalities:
- Ultrix, DEC OSF/1, and OSF/rose. (Alpha-based DECstation products
- have a configuration name beginning with `alpha-dec'.) To
- configure GCC for these platforms use the following configurations:
-
- `decstation-ultrix'
- Ultrix configuration.
-
- `decstation-osf1'
- Dec's version of OSF/1.
-
- `decstation-osfrose'
- Open Software Foundation reference port of OSF/1 which uses
- the OSF/rose object file format instead of ECOFF. Normally,
- you would not select this configuration.
-
- The MIPS C compiler needs to be told to increase its table size
- for switch statements with the `-Wf,-XNg1500' option in order to
- compile `cp/parse.c'. If you use the `-O2' optimization option,
- you also need to use `-Olimit 3000'. Both of these options are
- automatically generated in the `Makefile' that the shell script
- `configure' builds. If you override the `CC' make variable and
- use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
- 3000'.
-
-`elxsi-elxsi-bsd'
- The Elxsi's C compiler has known limitations that prevent it from
- compiling GNU C. Please contact <mrs@cygnus.com> for more details.
-
-`dsp16xx'
- A port to the AT&T DSP1610 family of processors.
-
-`h8300-*-*'
- Hitachi H8/300 series of processors.
-
- The calling convention and structure layout has changed in release
- 2.6. All code must be recompiled. The calling convention now
- passes the first three arguments in function calls in registers.
- Structures are no longer a multiple of 2 bytes.
-
-`hppa*-*-*'
- There are several variants of the HP-PA processor which run a
- variety of operating systems. GNU CC must be configured to use
- the correct processor type and operating system, or GNU CC will
- not function correctly. The easiest way to handle this problem is
- to *not* specify a target when configuring GNU CC, the `configure'
- script will try to automatically determine the right processor
- type and operating system.
-
- `-g' does not work on HP-UX, since that system uses a peculiar
- debugging format which GNU CC does not know about. However, `-g'
- will work if you also use GAS and GDB in conjunction with GCC. We
- highly recommend using GAS for all HP-PA configurations.
-
- You should be using GAS-2.6 (or later) along with GDB-4.16 (or
- later). These can be retrieved from all the traditional GNU ftp
- archive sites.
-
- On some versions of HP-UX, you will need to install GNU `sed'.
-
- You will need to be install GAS into a directory before `/bin',
- `/usr/bin', and `/usr/ccs/bin' in your search path. You should
- install GAS before you build GNU CC.
-
- To enable debugging, you must configure GNU CC with the
- `--with-gnu-as' option before building.
-
-`i370-*-*'
- This port is very preliminary and has many known bugs. We hope to
- have a higher-quality port for this machine soon.
-
-`i386-*-linux*oldld'
- Use this configuration to generate `a.out' binaries on Linux-based
- GNU systems if you do not have gas/binutils version 2.5.2 or later
- installed. This is an obsolete configuration.
-
-`i386-*-linux*aout'
- Use this configuration to generate `a.out' binaries on Linux-based
- GNU systems. This configuration is being superseded. You must use
- gas/binutils version 2.5.2 or later.
-
-`i386-*-linux'
-`i386-*-linux-gnu'
- Use this configuration to generate ELF binaries on Linux-based GNU
- systems. You must use gas/binutils version 2.5.2 or later.
-
-`i386-*-sco'
- Compilation with RCC is recommended. Also, it may be a good idea
- to link with GNU malloc instead of the malloc that comes with the
- system.
-
-`i386-*-sco3.2v4'
- Use this configuration for SCO release 3.2 version 4.
-
-`i386-*-sco3.2v5*'
- Use this for the SCO OpenServer Release family including 5.0.0,
- 5.0.2, 5.0.4, 5.0.5, Internet FastStart 1.0, and Internet
- FastStart 1.1.
-
- GNU CC can generate COFF binaries if you specify `-mcoff' or ELF
- binaries, the default. A full `make bootstrap' is recommended
- so that an ELF compiler that builds ELF is generated.
-
- You must have TLS597 from `ftp://ftp.sco.com/TLS' installed for ELF
- C++ binaries to work correctly on releases before 5.0.4.
-
- The native SCO assembler that is provided with the OS at no charge
- is normally required. If, however, you must be able to use the GNU
- assembler (perhaps you have complex asms) you must configure this
- package `--with-gnu-as'. To do this, install (cp or symlink)
- gcc/as to your copy of the GNU assembler. You must use a recent
- version of GNU binutils; version 2.9.1 seems to work well. If you
- select this option, you will be unable to build COFF images.
- Trying to do so will result in non-obvious failures. In general,
- the "-with-gnu-as" option isn't as well tested as the native
- assembler.
-
- *NOTE:* If you are building C++, you must follow the instructions
- about invoking `make bootstrap' because the native OpenServer
- compiler may build a `cc1plus' that will not correctly parse many
- valid C++ programs. You must do a `make bootstrap' if you are
- building with the native compiler.
-
-`i386-*-isc'
- It may be a good idea to link with GNU malloc instead of the
- malloc that comes with the system.
-
- In ISC version 4.1, `sed' core dumps when building `deduced.h'.
- Use the version of `sed' from version 4.0.
-
-`i386-*-esix'
- It may be good idea to link with GNU malloc instead of the malloc
- that comes with the system.
-
-`i386-ibm-aix'
- You need to use GAS version 2.1 or later, and LD from GNU binutils
- version 2.2 or later.
-
-`i386-sequent-bsd'
- Go to the Berkeley universe before compiling.
-
-`i386-sequent-ptx1*'
-`i386-sequent-ptx2*'
- You must install GNU `sed' before running `configure'.
-
-`i386-sun-sunos4'
- You may find that you need another version of GNU CC to begin
- bootstrapping with, since the current version when built with the
- system's own compiler seems to get an infinite loop compiling part
- of `libgcc2.c'. GNU CC version 2 compiled with GNU CC (any
- version) seems not to have this problem.
-
- See *Note Sun Install::, for information on installing GNU CC on
- Sun systems.
-
-`i[345]86-*-winnt3.5'
- This version requires a GAS that has not yet been released. Until
- it is, you can get a prebuilt binary version via anonymous ftp from
- `ftp://cs.washington.edu/pub/gnat' or `ftp://cs.nyu.edu/pub/gnat'.
- You must also use the Microsoft header files from the Windows NT
- 3.5 SDK. Find these on the CDROM in the `/mstools/h' directory
- dated 9/4/94. You must use a fixed version of Microsoft linker
- made especially for NT 3.5, which is also is available on the NT
- 3.5 SDK CDROM. If you do not have this linker, can you also use
- the linker from Visual C/C++ 1.0 or 2.0.
-
- Installing GNU CC for NT builds a wrapper linker, called `ld.exe',
- which mimics the behaviour of Unix `ld' in the specification of
- libraries (`-L' and `-l'). `ld.exe' looks for both Unix and
- Microsoft named libraries. For example, if you specify `-lfoo',
- `ld.exe' will look first for `libfoo.a' and then for `foo.lib'.
-
- You may install GNU CC for Windows NT in one of two ways,
- depending on whether or not you have a Unix-like shell and various
- Unix-like utilities.
-
- 1. If you do not have a Unix-like shell and few Unix-like
- utilities, you will use a DOS style batch script called
- `configure.bat'. Invoke it as `configure winnt' from an
- MSDOS console window or from the program manager dialog box.
- `configure.bat' assumes you have already installed and have
- in your path a Unix-like `sed' program which is used to
- create a working `Makefile' from `Makefile.in'.
-
- `Makefile' uses the Microsoft Nmake program maintenance
- utility and the Visual C/C++ V8.00 compiler to build GNU CC.
- You need only have the utilities `sed' and `touch' to use
- this installation method, which only automatically builds the
- compiler itself. You must then examine what `fixinc.winnt'
- does, edit the header files by hand and build `libgcc.a'
- manually.
-
- 2. The second type of installation assumes you are running a
- Unix-like shell, have a complete suite of Unix-like utilities
- in your path, and have a previous version of GNU CC already
- installed, either through building it via the above
- installation method or acquiring a pre-built binary. In this
- case, use the `configure' script in the normal fashion.
-
-`i860-intel-osf1'
- This is the Paragon. If you have version 1.0 of the operating
- system, you need to take special steps to build GNU CC due to
- peculiarities of the system. Newer system versions have no
- problem. See the section `Installation Problems' in the GNU CC
- Manual.
-
-`*-lynx-lynxos'
- LynxOS 2.2 and earlier comes with GNU CC 1.x already installed as
- `/bin/gcc'. You should compile with this instead of `/bin/cc'.
- You can tell GNU CC to use the GNU assembler and linker, by
- specifying `--with-gnu-as --with-gnu-ld' when configuring. These
- will produce COFF format object files and executables; otherwise
- GNU CC will use the installed tools, which produce `a.out' format
- executables.
-
-`m32r-*-elf'
- Mitsubishi M32R processor. This configuration is intended for
- embedded systems.
-
-`m68000-hp-bsd'
- HP 9000 series 200 running BSD. Note that the C compiler that
- comes with this system cannot compile GNU CC; contact
- <law@cygnus.com> to get binaries of GNU CC for bootstrapping.
-
-`m68k-altos'
- Altos 3068. You must use the GNU assembler, linker and debugger.
- Also, you must fix a kernel bug. Details in the file
- `README.ALTOS'.
-
-`m68k-apple-aux'
- Apple Macintosh running A/UX. You may configure GCC to use
- either the system assembler and linker or the GNU assembler and
- linker. You should use the GNU configuration if you can,
- especially if you also want to use GNU C++. You enabled that
- configuration with + the `--with-gnu-as' and `--with-gnu-ld'
- options to `configure'.
-
- Note the C compiler that comes with this system cannot compile GNU
- CC. You can find binaries of GNU CC for bootstrapping on
- `jagubox.gsfc.nasa.gov'. You will also a patched version of
- `/bin/ld' there that raises some of the arbitrary limits found in
- the original.
-
-`m68k-att-sysv'
- AT&T 3b1, a.k.a. 7300 PC. This version of GNU CC cannot be
- compiled with the system C compiler, which is too buggy. You will
- need to get a previous version of GCC and use it to bootstrap.
- Binaries are available from the OSU-CIS archive, at
- `ftp://archive.cis.ohio-state.edu/pub/att7300/'.
-
-`m68k-bull-sysv'
- Bull DPX/2 series 200 and 300 with BOS-2.00.45 up to BOS-2.01. GNU
- CC works either with native assembler or GNU assembler. You can use
- GNU assembler with native coff generation by providing
- `--with-gnu-as' to the configure script or use GNU assembler with
- dbx-in-coff encapsulation by providing `--with-gnu-as --stabs'.
- For any problem with native assembler or for availability of the
- DPX/2 port of GAS, contact <F.Pierresteguy@frcl.bull.fr>.
-
-`m68k-crds-unox'
- Use `configure unos' for building on Unos.
-
- The Unos assembler is named `casm' instead of `as'. For some
- strange reason linking `/bin/as' to `/bin/casm' changes the
- behavior, and does not work. So, when installing GNU CC, you
- should install the following script as `as' in the subdirectory
- where the passes of GCC are installed:
-
- #!/bin/sh
- casm $*
-
- The default Unos library is named `libunos.a' instead of `libc.a'.
- To allow GNU CC to function, either change all references to
- `-lc' in `gcc.c' to `-lunos' or link `/lib/libc.a' to
- `/lib/libunos.a'.
-
- When compiling GNU CC with the standard compiler, to overcome bugs
- in the support of `alloca', do not use `-O' when making stage 2.
- Then use the stage 2 compiler with `-O' to make the stage 3
- compiler. This compiler will have the same characteristics as the
- usual stage 2 compiler on other systems. Use it to make a stage 4
- compiler and compare that with stage 3 to verify proper
- compilation.
-
- (Perhaps simply defining `ALLOCA' in `x-crds' as described in the
- comments there will make the above paragraph superfluous. Please
- inform us of whether this works.)
-
- Unos uses memory segmentation instead of demand paging, so you
- will need a lot of memory. 5 Mb is barely enough if no other
- tasks are running. If linking `cc1' fails, try putting the object
- files into a library and linking from that library.
-
-`m68k-hp-hpux'
- HP 9000 series 300 or 400 running HP-UX. HP-UX version 8.0 has a
- bug in the assembler that prevents compilation of GNU CC. To fix
- it, get patch PHCO_4484 from HP.
-
- In addition, if you wish to use gas `--with-gnu-as' you must use
- gas version 2.1 or later, and you must use the GNU linker version
- 2.1 or later. Earlier versions of gas relied upon a program which
- converted the gas output into the native HP-UX format, but that
- program has not been kept up to date. gdb does not understand
- that native HP-UX format, so you must use gas if you wish to use
- gdb.
-
-`m68k-sun'
- Sun 3. We do not provide a configuration file to use the Sun FPA
- by default, because programs that establish signal handlers for
- floating point traps inherently cannot work with the FPA.
-
- See *Note Sun Install::, for information on installing GNU CC on
- Sun systems.
-
-`m6811-elf'
- Motorola 68HC11 family micro controllers. These are used in
- embedded applications. There are no standard Unix configurations.
-
-`m6812-elf'
- Motorola 68HC12 family micro controllers. These are used in
- embedded applications. There are no standard Unix configurations.
-
-`m88k-*-svr3'
- Motorola m88k running the AT&T/Unisoft/Motorola V.3 reference port.
- These systems tend to use the Green Hills C, revision 1.8.5, as the
- standard C compiler. There are apparently bugs in this compiler
- that result in object files differences between stage 2 and stage
- 3. If this happens, make the stage 4 compiler and compare it to
- the stage 3 compiler. If the stage 3 and stage 4 object files are
- identical, this suggests you encountered a problem with the
- standard C compiler; the stage 3 and 4 compilers may be usable.
-
- It is best, however, to use an older version of GNU CC for
- bootstrapping if you have one.
-
-`m88k-*-dgux'
- Motorola m88k running DG/UX. To build 88open BCS native or cross
- compilers on DG/UX, specify the configuration name as
- `m88k-*-dguxbcs' and build in the 88open BCS software development
- environment. To build ELF native or cross compilers on DG/UX,
- specify `m88k-*-dgux' and build in the DG/UX ELF development
- environment. You set the software development environment by
- issuing `sde-target' command and specifying either `m88kbcs' or
- `m88kdguxelf' as the operand.
-
- If you do not specify a configuration name, `configure' guesses the
- configuration based on the current software development
- environment.
-
-`m88k-tektronix-sysv3'
- Tektronix XD88 running UTekV 3.2e. Do not turn on optimization
- while building stage1 if you bootstrap with the buggy Green Hills
- compiler. Also, The bundled LAI System V NFS is buggy so if you
- build in an NFS mounted directory, start from a fresh reboot, or
- avoid NFS all together. Otherwise you may have trouble getting
- clean comparisons between stages.
-
-`mips-mips-bsd'
- MIPS machines running the MIPS operating system in BSD mode. It's
- possible that some old versions of the system lack the functions
- `memcpy', `memcmp', and `memset'. If your system lacks these, you
- must remove or undo the definition of `TARGET_MEM_FUNCTIONS' in
- `mips-bsd.h'.
-
- The MIPS C compiler needs to be told to increase its table size
- for switch statements with the `-Wf,-XNg1500' option in order to
- compile `cp/parse.c'. If you use the `-O2' optimization option,
- you also need to use `-Olimit 3000'. Both of these options are
- automatically generated in the `Makefile' that the shell script
- `configure' builds. If you override the `CC' make variable and
- use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
- 3000'.
-
-`mips-mips-riscos*'
- The MIPS C compiler needs to be told to increase its table size
- for switch statements with the `-Wf,-XNg1500' option in order to
- compile `cp/parse.c'. If you use the `-O2' optimization option,
- you also need to use `-Olimit 3000'. Both of these options are
- automatically generated in the `Makefile' that the shell script
- `configure' builds. If you override the `CC' make variable and
- use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
- 3000'.
-
- MIPS computers running RISC-OS can support four different
- personalities: default, BSD 4.3, System V.3, and System V.4 (older
- versions of RISC-OS don't support V.4). To configure GCC for
- these platforms use the following configurations:
-
- `mips-mips-riscos`rev''
- Default configuration for RISC-OS, revision `rev'.
-
- `mips-mips-riscos`rev'bsd'
- BSD 4.3 configuration for RISC-OS, revision `rev'.
-
- `mips-mips-riscos`rev'sysv4'
- System V.4 configuration for RISC-OS, revision `rev'.
-
- `mips-mips-riscos`rev'sysv'
- System V.3 configuration for RISC-OS, revision `rev'.
-
- The revision `rev' mentioned above is the revision of RISC-OS to
- use. You must reconfigure GCC when going from a RISC-OS revision
- 4 to RISC-OS revision 5. This has the effect of avoiding a linker
- bug.
-
-`mips-sgi-*'
- In order to compile GCC on an SGI running IRIX 4, the "c.hdr.lib"
- option must be installed from the CD-ROM supplied from Silicon
- Graphics. This is found on the 2nd CD in release 4.0.1.
-
- In order to compile GCC on an SGI running IRIX 5, the
- "compiler_dev.hdr" subsystem must be installed from the IDO CD-ROM
- supplied by Silicon Graphics.
-
- `make compare' may fail on version 5 of IRIX unless you add
- `-save-temps' to `CFLAGS'. On these systems, the name of the
- assembler input file is stored in the object file, and that makes
- comparison fail if it differs between the `stage1' and `stage2'
- compilations. The option `-save-temps' forces a fixed name to be
- used for the assembler input file, instead of a randomly chosen
- name in `/tmp'. Do not add `-save-temps' unless the comparisons
- fail without that option. If you do you `-save-temps', you will
- have to manually delete the `.i' and `.s' files after each series
- of compilations.
-
- The MIPS C compiler needs to be told to increase its table size
- for switch statements with the `-Wf,-XNg1500' option in order to
- compile `cp/parse.c'. If you use the `-O2' optimization option,
- you also need to use `-Olimit 3000'. Both of these options are
- automatically generated in the `Makefile' that the shell script
- `configure' builds. If you override the `CC' make variable and
- use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
- 3000'.
-
- On Irix version 4.0.5F, and perhaps on some other versions as well,
- there is an assembler bug that reorders instructions incorrectly.
- To work around it, specify the target configuration
- `mips-sgi-irix4loser'. This configuration inhibits assembler
- optimization.
-
- In a compiler configured with target `mips-sgi-irix4', you can turn
- off assembler optimization by using the `-noasmopt' option. This
- compiler option passes the option `-O0' to the assembler, to
- inhibit reordering.
-
- The `-noasmopt' option can be useful for testing whether a problem
- is due to erroneous assembler reordering. Even if a problem does
- not go away with `-noasmopt', it may still be due to assembler
- reordering--perhaps GNU CC itself was miscompiled as a result.
-
- To enable debugging under Irix 5, you must use GNU as 2.5 or later,
- and use the `--with-gnu-as' configure option when configuring gcc.
- GNU as is distributed as part of the binutils package.
-
-`mips-sony-sysv'
- Sony MIPS NEWS. This works in NEWSOS 5.0.1, but not in 5.0.2
- (which uses ELF instead of COFF). Support for 5.0.2 will probably
- be provided soon by volunteers. In particular, the linker does
- not like the code generated by GCC when shared libraries are
- linked in.
-
-`ns32k-encore'
- Encore ns32000 system. Encore systems are supported only under
- BSD.
-
-`ns32k-*-genix'
- National Semiconductor ns32000 system. Genix has bugs in `alloca'
- and `malloc'; you must get the compiled versions of these from GNU
- Emacs.
-
-`ns32k-sequent'
- Go to the Berkeley universe before compiling.
-
-`ns32k-utek'
- UTEK ns32000 system ("merlin"). The C compiler that comes with
- this system cannot compile GNU CC; contact `tektronix!reed!mason'
- to get binaries of GNU CC for bootstrapping.
-
-`romp-*-aos'
-`romp-*-mach'
- The only operating systems supported for the IBM RT PC are AOS and
- MACH. GNU CC does not support AIX running on the RT. We
- recommend you compile GNU CC with an earlier version of itself; if
- you compile GNU CC with `hc', the Metaware compiler, it will work,
- but you will get mismatches between the stage 2 and stage 3
- compilers in various files. These errors are minor differences in
- some floating-point constants and can be safely ignored; the stage
- 3 compiler is correct.
-
-`rs6000-*-aix'
-`powerpc-*-aix'
- Various early versions of each release of the IBM XLC compiler
- will not bootstrap GNU CC. Symptoms include differences between
- the stage2 and stage3 object files, and errors when compiling
- `libgcc.a' or `enquire'. Known problematic releases include:
- xlc-1.2.1.8, xlc-1.3.0.0 (distributed with AIX 3.2.5), and
- xlc-1.3.0.19. Both xlc-1.2.1.28 and xlc-1.3.0.24 (PTF 432238) are
- known to produce working versions of GNU CC, but most other recent
- releases correctly bootstrap GNU CC.
-
- Release 4.3.0 of AIX and ones prior to AIX 3.2.4 include a version
- of the IBM assembler which does not accept debugging directives:
- assembler updates are available as PTFs. Also, if you are using
- AIX 3.2.5 or greater and the GNU assembler, you must have a
- version modified after October 16th, 1995 in order for the GNU C
- compiler to build. See the file `README.RS6000' for more details
- on any of these problems.
-
- GNU CC does not yet support the 64-bit PowerPC instructions.
-
- Objective C does not work on this architecture because it makes
- assumptions that are incompatible with the calling conventions.
-
- AIX on the RS/6000 provides support (NLS) for environments outside
- of the United States. Compilers and assemblers use NLS to support
- locale-specific representations of various objects including
- floating-point numbers ("." vs "," for separating decimal
- fractions). There have been problems reported where the library
- linked with GNU CC does not produce the same floating-point
- formats that the assembler accepts. If you have this problem, set
- the LANG environment variable to "C" or "En_US".
-
- Due to changes in the way that GNU CC invokes the binder (linker)
- for AIX 4.1, you may now receive warnings of duplicate symbols
- from the link step that were not reported before. The assembly
- files generated by GNU CC for AIX have always included multiple
- symbol definitions for certain global variable and function
- declarations in the original program. The warnings should not
- prevent the linker from producing a correct library or runnable
- executable.
-
- By default, AIX 4.1 produces code that can be used on either Power
- or PowerPC processors.
-

-
- You can specify a default version for the `-mcpu='CPU_TYPE switch

-
-`vax-dec-ultrix'
- Don't try compiling with Vax C (`vcc'). It produces incorrect code
- in some cases (for example, when `alloca' is used).
-
- Meanwhile, compiling `cp/parse.c' with pcc does not work because of
- an internal table size limitation in that compiler. To avoid this
- problem, compile just the GNU C compiler first, and use it to
- recompile building all the languages that you want to run.
-
-`sparc-sun-*'
- See *Note Sun Install::, for information on installing GNU CC on
- Sun systems.
-
-`vax-dec-vms'
- See *Note VMS Install::, for details on how to install GNU CC on

-
-`we32k-*-*'
- These computers are also known as the 3b2, 3b5, 3b20 and other
- similar names. (However, the 3b1 is actually a 68000; see *Note
- Configurations::.)
-
- Don't use `-g' when compiling with the system's compiler. The
- system's linker seems to be unable to handle such a large program
- with debugging information.
-
- The system's compiler runs out of capacity when compiling `stmt.c'
- in GNU CC. You can work around this by building `cpp' in GNU CC
- first, then use that instead of the system's preprocessor with the
- system's C compiler to compile `stmt.c'. Here is how:
-
- mv /lib/cpp /lib/cpp.att
- cp cpp /lib/cpp.gnu
- echo '/lib/cpp.gnu -traditional ${1+"$@"}' > /lib/cpp
- chmod +x /lib/cpp
-
- The system's compiler produces bad code for some of the GNU CC
- optimization files. So you must build the stage 2 compiler without
- optimization. Then build a stage 3 compiler with optimization.
- That executable should work. Here are the necessary commands:
-
- make LANGUAGES=c CC=stage1/xgcc CFLAGS="-Bstage1/ -g"
- make stage2
- make CC=stage2/xgcc CFLAGS="-Bstage2/ -g -O"
-
- You may need to raise the ULIMIT setting to build a C++ compiler,
- as the file `cc1plus' is larger than one megabyte.
-
-Compilation in a Separate Directory
-===================================
-
- If you wish to build the object files and executables in a directory
-other than the one containing the source files, here is what you must
-do differently:
-
- 1. Make sure you have a version of Make that supports the `VPATH'
- feature. (GNU Make supports it, as do Make versions on most BSD
- systems.)
-
- 2. If you have ever run `configure' in the source directory, you must
- undo the configuration. Do this by running:
-
- make distclean
-
- 3. Go to the directory in which you want to build the compiler before
- running `configure':
-
- mkdir gcc-sun3
- cd gcc-sun3
-
- On systems that do not support symbolic links, this directory must
- be on the same file system as the source code directory.
-
- 4. Specify where to find `configure' when you run it:
-
- ../gcc/configure ...
-
- This also tells `configure' where to find the compiler sources;
- `configure' takes the directory from the file name that was used to
- invoke it. But if you want to be sure, you can specify the source
- directory with the `--srcdir' option, like this:
-
- ../gcc/configure --srcdir=../gcc OTHER OPTIONS
-
- The directory you specify with `--srcdir' need not be the same as
- the one that `configure' is found in.
-
- Now, you can run `make' in that directory. You need not repeat the
-configuration steps shown above, when ordinary source files change. You
-must, however, run `configure' again when the configuration files
-change, if your system does not support symbolic links.
-
-Building and Installing a Cross-Compiler
-========================================
-
- GNU CC can function as a cross-compiler for many machines, but not
-all.
-
- * Cross-compilers for the Mips as target using the Mips assembler
- currently do not work, because the auxiliary programs
- `mips-tdump.c' and `mips-tfile.c' can't be compiled on anything
- but a Mips. It does work to cross compile for a Mips if you use
- the GNU assembler and linker.
-
- * Cross-compilers between machines with different floating point
- formats have not all been made to work. GNU CC now has a floating
- point emulator with which these can work, but each target machine
- description needs to be updated to take advantage of it.
-
- * Cross-compilation between machines of different word sizes is
- somewhat problematic and sometimes does not work.
-
- Since GNU CC generates assembler code, you probably need a
-cross-assembler that GNU CC can run, in order to produce object files.
-If you want to link on other than the target machine, you need a
-cross-linker as well. You also need header files and libraries suitable
-for the target machine that you can install on the host machine.
-
-Steps of Cross-Compilation
---------------------------
-
- To compile and run a program using a cross-compiler involves several
-steps:
-
- * Run the cross-compiler on the host machine to produce assembler
- files for the target machine. This requires header files for the
- target machine.
-
- * Assemble the files produced by the cross-compiler. You can do this
- either with an assembler on the target machine, or with a
- cross-assembler on the host machine.
-
- * Link those files to make an executable. You can do this either
- with a linker on the target machine, or with a cross-linker on the
- host machine. Whichever machine you use, you need libraries and
- certain startup files (typically `crt....o') for the target
- machine.
-
- It is most convenient to do all of these steps on the same host
-machine, since then you can do it all with a single invocation of GNU
-CC. This requires a suitable cross-assembler and cross-linker. For
-some targets, the GNU assembler and linker are available.
-
-Configuring a Cross-Compiler
-----------------------------
-
- To build GNU CC as a cross-compiler, you start out by running
-`configure'. Use the `--target=TARGET' to specify the target type. If
-`configure' was unable to correctly identify the system you are running
-on, also specify the `--build=BUILD' option. For example, here is how
-to configure for a cross-compiler that produces code for an HP 68030
-system running BSD on a system that `configure' can correctly identify:
-
- ./configure --target=m68k-hp-bsd4.3
-
-Tools and Libraries for a Cross-Compiler
-----------------------------------------
-
- If you have a cross-assembler and cross-linker available, you should
-install them now. Put them in the directory `/usr/local/TARGET/bin'.
-Here is a table of the tools you should put in this directory:
-
-`as'
- This should be the cross-assembler.
-
-`ld'
- This should be the cross-linker.
-
-`ar'
- This should be the cross-archiver: a program which can manipulate
- archive files (linker libraries) in the target machine's format.
-
-`ranlib'
- This should be a program to construct a symbol table in an archive
- file.
-
- The installation of GNU CC will find these programs in that
-directory, and copy or link them to the proper place to for the
-cross-compiler to find them when run later.
-
- The easiest way to provide these files is to build the Binutils
-package and GAS. Configure them with the same `--host' and `--target'
-options that you use for configuring GNU CC, then build and install
-them. They install their executables automatically into the proper
-directory. Alas, they do not support all the targets that GNU CC
-supports.
-
- If you want to install libraries to use with the cross-compiler,
-such as a standard C library, put them in the directory
-`/usr/local/TARGET/lib'; installation of GNU CC copies all the files in
-that subdirectory into the proper place for GNU CC to find them and
-link with them. Here's an example of copying some libraries from a
-target machine:
-
- ftp TARGET-MACHINE
- lcd /usr/local/TARGET/lib
- cd /lib
- get libc.a
- cd /usr/lib
- get libg.a
- get libm.a
- quit
-
-The precise set of libraries you'll need, and their locations on the
-target machine, vary depending on its operating system.
-
- Many targets require "start files" such as `crt0.o' and `crtn.o'
-which are linked into each executable; these too should be placed in
-`/usr/local/TARGET/lib'. There may be several alternatives for
-`crt0.o', for use with profiling or other compilation options. Check
-your target's definition of `STARTFILE_SPEC' to find out what start
-files it uses. Here's an example of copying these files from a target
-machine:
-
- ftp TARGET-MACHINE
- lcd /usr/local/TARGET/lib
- prompt
- cd /lib
- mget *crt*.o
- cd /usr/lib
- mget *crt*.o
- quit
-
-`libgcc.a' and Cross-Compilers
-------------------------------
-
- Code compiled by GNU CC uses certain runtime support functions
-implicitly. Some of these functions can be compiled successfully with
-GNU CC itself, but a few cannot be. These problem functions are in the
-source file `libgcc1.c'; the library made from them is called
-`libgcc1.a'.
-
- When you build a native compiler, these functions are compiled with
-some other compiler-the one that you use for bootstrapping GNU CC.
-Presumably it knows how to open code these operations, or else knows how
-to call the run-time emulation facilities that the machine comes with.
-But this approach doesn't work for building a cross-compiler. The
-compiler that you use for building knows about the host system, not the
-target system.
-
- So, when you build a cross-compiler you have to supply a suitable
-library `libgcc1.a' that does the job it is expected to do.
-
- To compile `libgcc1.c' with the cross-compiler itself does not work.
-The functions in this file are supposed to implement arithmetic
-operations that GNU CC does not know how to open code for your target
-machine. If these functions are compiled with GNU CC itself, they will
-compile into infinite recursion.
-
- On any given target, most of these functions are not needed. If GNU
-CC can open code an arithmetic operation, it will not call these
-functions to perform the operation. It is possible that on your target
-machine, none of these functions is needed. If so, you can supply an
-empty library as `libgcc1.a'.
-
- Many targets need library support only for multiplication and
-division. If you are linking with a library that contains functions for
-multiplication and division, you can tell GNU CC to call them directly
-by defining the macros `MULSI3_LIBCALL', and the like. These macros
-need to be defined in the target description macro file. For some
-targets, they are defined already. This may be sufficient to avoid the
-need for libgcc1.a; if so, you can supply an empty library.
-
- Some targets do not have floating point instructions; they need other
-functions in `libgcc1.a', which do floating arithmetic. Recent
-versions of GNU CC have a file which emulates floating point. With a
-certain amount of work, you should be able to construct a floating
-point emulator that can be used as `libgcc1.a'. Perhaps future
-versions will contain code to do this automatically and conveniently.
-That depends on whether someone wants to implement it.
-
- Some embedded targets come with all the necessary `libgcc1.a'
-routines written in C or assembler. These targets build `libgcc1.a'
-automatically and you do not need to do anything special for them.
-Other embedded targets do not need any `libgcc1.a' routines since all
-the necessary operations are supported by the hardware.
-
- If your target system has another C compiler, you can configure GNU
-CC as a native compiler on that machine, build just `libgcc1.a' with
-`make libgcc1.a' on that machine, and use the resulting file with the
-cross-compiler. To do this, execute the following on the target
-machine:
-
- cd TARGET-BUILD-DIR
- ./configure --host=sparc --target=sun3
- make libgcc1.a
-
-And then this on the host machine:
-
- ftp TARGET-MACHINE
- binary
- cd TARGET-BUILD-DIR
- get libgcc1.a
- quit
-
- Another way to provide the functions you need in `libgcc1.a' is to
-define the appropriate `perform_...' macros for those functions. If
-these definitions do not use the C arithmetic operators that they are
-meant to implement, you should be able to compile them with the
-cross-compiler you are building. (If these definitions already exist
-for your target file, then you are all set.)
-
- To build `libgcc1.a' using the perform macros, use
-`LIBGCC1=libgcc1.a OLDCC=./xgcc' when building the compiler.
-Otherwise, you should place your replacement library under the name
-`libgcc1.a' in the directory in which you will build the
-cross-compiler, before you run `make'.
-
-Cross-Compilers and Header Files
---------------------------------
-
- If you are cross-compiling a standalone program or a program for an
-embedded system, then you may not need any header files except the few
-that are part of GNU CC (and those of your program). However, if you
-intend to link your program with a standard C library such as `libc.a',
-then you probably need to compile with the header files that go with
-the library you use.
-
- The GNU C compiler does not come with these files, because (1) they
-are system-specific, and (2) they belong in a C library, not in a
-compiler.
-
- If the GNU C library supports your target machine, then you can get
-the header files from there (assuming you actually use the GNU library
-when you link your program).
-
- If your target machine comes with a C compiler, it probably comes
-with suitable header files also. If you make these files accessible
-from the host machine, the cross-compiler can use them also.
-
- Otherwise, you're on your own in finding header files to use when
-cross-compiling.
-
- When you have found suitable header files, put them in the directory
-`/usr/local/TARGET/include', before building the cross compiler. Then
-installation will run fixincludes properly and install the corrected
-versions of the header files where the compiler will use them.
-
- Provide the header files before you build the cross-compiler, because
-the build stage actually runs the cross-compiler to produce parts of
-`libgcc.a'. (These are the parts that *can* be compiled with GNU CC.)
-Some of them need suitable header files.
-
- Here's an example showing how to copy the header files from a target
-machine. On the target machine, do this:
-
- (cd /usr/include; tar cf - .) > tarfile
-
- Then, on the host machine, do this:
-
- ftp TARGET-MACHINE
- lcd /usr/local/TARGET/include
- get tarfile
- quit
- tar xf tarfile
-
-Actually Building the Cross-Compiler
-------------------------------------
-
- Now you can proceed just as for compiling a single-machine compiler
-through the step of building stage 1. If you have not provided some
-sort of `libgcc1.a', then compilation will give up at the point where
-it needs that file, printing a suitable error message. If you do
-provide `libgcc1.a', then building the compiler will automatically
-compile and link a test program called `libgcc1-test'; if you get
-errors in the linking, it means that not all of the necessary routines
-in `libgcc1.a' are available.
-
- You must provide the header file `float.h'. One way to do this is
-to compile `enquire' and run it on your target machine. The job of
-`enquire' is to run on the target machine and figure out by experiment
-the nature of its floating point representation. `enquire' records its
-findings in the header file `float.h'. If you can't produce this file
-by running `enquire' on the target machine, then you will need to come
-up with a suitable `float.h' in some other way (or else, avoid using it
-in your programs).
-
- Do not try to build stage 2 for a cross-compiler. It doesn't work to
-rebuild GNU CC as a cross-compiler using the cross-compiler, because
-that would produce a program that runs on the target machine, not on the
-host. For example, if you compile a 386-to-68030 cross-compiler with
-itself, the result will not be right either for the 386 (because it was
-compiled into 68030 code) or for the 68030 (because it was configured
-for a 386 as the host). If you want to compile GNU CC into 68030 code,
-whether you compile it on a 68030 or with a cross-compiler on a 386, you
-must specify a 68030 as the host when you configure it.
-
- To install the cross-compiler, use `make install', as usual.
-
-Installing GNU CC on the Sun
-============================
-
- On Solaris, do not use the linker or other tools in `/usr/ucb' to
-build GNU CC. Use `/usr/ccs/bin'.
-
- If the assembler reports `Error: misaligned data' when bootstrapping,
-you are probably using an obsolete version of the GNU assembler.
-Upgrade to the latest version of GNU `binutils', or use the Solaris
-assembler.
-
- Make sure the environment variable `FLOAT_OPTION' is not set when
-you compile `libgcc.a'. If this option were set to `f68881' when
-`libgcc.a' is compiled, the resulting code would demand to be linked
-with a special startup file and would not link properly without special
-pains.
-
- There is a bug in `alloca' in certain versions of the Sun library.
-To avoid this bug, install the binaries of GNU CC that were compiled by
-GNU CC. They use `alloca' as a built-in function and never the one in
-the library.
-
- Some versions of the Sun compiler crash when compiling GNU CC. The
-problem is a segmentation fault in cpp. This problem seems to be due to
-the bulk of data in the environment variables. You may be able to avoid
-it by using the following command to compile GNU CC with Sun CC:
-
- make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc"
-
- SunOS 4.1.3 and 4.1.3_U1 have bugs that can cause intermittent core
-dumps when compiling GNU CC. A common symptom is an internal compiler
-error which does not recur if you run it again. To fix the problem,
-install Sun recommended patch 100726 (for SunOS 4.1.3) or 101508 (for
-SunOS 4.1.3_U1), or upgrade to a later SunOS release.
-
-Installing GNU CC on VMS
-========================
-
- The VMS version of GNU CC is distributed in a backup saveset
-containing both source code and precompiled binaries.
-
- To install the `gcc' command so you can use the compiler easily, in
-the same manner as you use the VMS C compiler, you must install the VMS
-CLD file for GNU CC as follows:
-
- 1. Define the VMS logical names `GNU_CC' and `GNU_CC_INCLUDE' to
- point to the directories where the GNU CC executables
- (`gcc-cpp.exe', `gcc-cc1.exe', etc.) and the C include files are
- kept respectively. This should be done with the commands:
-
- $ assign /system /translation=concealed -
- disk:[gcc.] gnu_cc
- $ assign /system /translation=concealed -
- disk:[gcc.include.] gnu_cc_include
-
- with the appropriate disk and directory names. These commands can
- be placed in your system startup file so they will be executed
- whenever the machine is rebooted. You may, if you choose, do this
- via the `GCC_INSTALL.COM' script in the `[GCC]' directory.
-
- 2. Install the `GCC' command with the command line:
-
- $ set command /table=sys$common:[syslib]dcltables -
- /output=sys$common:[syslib]dcltables gnu_cc:[000000]gcc
- $ install replace sys$common:[syslib]dcltables
-
- 3. To install the help file, do the following:
-
- $ library/help sys$library:helplib.hlb gcc.hlp
-
- Now you can invoke the compiler with a command like `gcc /verbose
- file.c', which is equivalent to the command `gcc -v -c file.c' in
- Unix.
-
- If you wish to use GNU C++ you must first install GNU CC, and then
-perform the following steps:
-
- 1. Define the VMS logical name `GNU_GXX_INCLUDE' to point to the
- directory where the preprocessor will search for the C++ header
- files. This can be done with the command:
-
- $ assign /system /translation=concealed -
- disk:[gcc.gxx_include.] gnu_gxx_include
-
- with the appropriate disk and directory name. If you are going to
- be using a C++ runtime library, this is where its install
- procedure will install its header files.
-
- 2. Obtain the file `gcc-cc1plus.exe', and place this in the same
- directory that `gcc-cc1.exe' is kept.
-
- The GNU C++ compiler can be invoked with a command like `gcc /plus
- /verbose file.cc', which is equivalent to the command `g++ -v -c
- file.cc' in Unix.
-
- We try to put corresponding binaries and sources on the VMS
-distribution tape. But sometimes the binaries will be from an older
-version than the sources, because we don't always have time to update
-them. (Use the `/version' option to determine the version number of
-the binaries and compare it with the source file `version.c' to tell
-whether this is so.) In this case, you should use the binaries you get
-to recompile the sources. If you must recompile, here is how:
-
- 1. Execute the command procedure `vmsconfig.com' to set up the files
- `tm.h', `config.h', `aux-output.c', and `md.', and to create files
- `tconfig.h' and `hconfig.h'. This procedure also creates several
- linker option files used by `make-cc1.com' and a data file used by
- `make-l2.com'.
-
- $ @vmsconfig.com
-
- 2. Setup the logical names and command tables as defined above. In
- addition, define the VMS logical name `GNU_BISON' to point at the
- to the directories where the Bison executable is kept. This
- should be done with the command:
-
- $ assign /system /translation=concealed -
- disk:[bison.] gnu_bison
-
- You may, if you choose, use the `INSTALL_BISON.COM' script in the
- `[BISON]' directory.
-
- 3. Install the `BISON' command with the command line:
-
- $ set command /table=sys$common:[syslib]dcltables -
- /output=sys$common:[syslib]dcltables -
- gnu_bison:[000000]bison
- $ install replace sys$common:[syslib]dcltables
-
- 4. Type `@make-gcc' to recompile everything (alternatively, submit
- the file `make-gcc.com' to a batch queue). If you wish to build
- the GNU C++ compiler as well as the GNU CC compiler, you must
- first edit `make-gcc.com' and follow the instructions that appear
- in the comments.
-
- 5. In order to use GCC, you need a library of functions which GCC
- compiled code will call to perform certain tasks, and these
- functions are defined in the file `libgcc2.c'. To compile this
- you should use the command procedure `make-l2.com', which will
- generate the library `libgcc2.olb'. `libgcc2.olb' should be built
- using the compiler built from the same distribution that
- `libgcc2.c' came from, and `make-gcc.com' will automatically do
- all of this for you.
-
- To install the library, use the following commands:
-
- $ library gnu_cc:[000000]gcclib/delete=(new,eprintf)
- $ library gnu_cc:[000000]gcclib/delete=L_*
- $ library libgcc2/extract=*/output=libgcc2.obj
- $ library gnu_cc:[000000]gcclib libgcc2.obj
-
- The first command simply removes old modules that will be replaced
- with modules from `libgcc2' under different module names. The
- modules `new' and `eprintf' may not actually be present in your
- `gcclib.olb'--if the VMS librarian complains about those modules
- not being present, simply ignore the message and continue on with
- the next command. The second command removes the modules that
- came from the previous version of the library `libgcc2.c'.
-
- Whenever you update the compiler on your system, you should also
- update the library with the above procedure.
-
- 6. You may wish to build GCC in such a way that no files are written
- to the directory where the source files reside. An example would
- be the when the source files are on a read-only disk. In these
- cases, execute the following DCL commands (substituting your
- actual path names):
-
- $ assign dua0:[gcc.build_dir.]/translation=concealed, -
- dua1:[gcc.source_dir.]/translation=concealed gcc_build
- $ set default gcc_build:[000000]
-
- where the directory `dua1:[gcc.source_dir]' contains the source
- code, and the directory `dua0:[gcc.build_dir]' is meant to contain
- all of the generated object files and executables. Once you have
- done this, you can proceed building GCC as described above. (Keep
- in mind that `gcc_build' is a rooted logical name, and thus the
- device names in each element of the search list must be an actual
- physical device name rather than another rooted logical name).
-
- 7. *If you are building GNU CC with a previous version of GNU CC, you
- also should check to see that you have the newest version of the
- assembler*. In particular, GNU CC version 2 treats global constant
- variables slightly differently from GNU CC version 1, and GAS
- version 1.38.1 does not have the patches required to work with GCC
- version 2. If you use GAS 1.38.1, then `extern const' variables
- will not have the read-only bit set, and the linker will generate
- warning messages about mismatched psect attributes for these
- variables. These warning messages are merely a nuisance, and can
- safely be ignored.
-
- If you are compiling with a version of GNU CC older than 1.33,
- specify `/DEFINE=("inline=")' as an option in all the
- compilations. This requires editing all the `gcc' commands in
- `make-cc1.com'. (The older versions had problems supporting
- `inline'.) Once you have a working 1.33 or newer GNU CC, you can
- change this file back.
-
- 8. If you want to build GNU CC with the VAX C compiler, you will need
- to make minor changes in `make-cccp.com' and `make-cc1.com' to
- choose alternate definitions of `CC', `CFLAGS', and `LIBS'. See
- comments in those files. However, you must also have a working
- version of the GNU assembler (GNU as, aka GAS) as it is used as
- the back-end for GNU CC to produce binary object modules and is
- not included in the GNU CC sources. GAS is also needed to compile
- `libgcc2' in order to build `gcclib' (see above); `make-l2.com'
- expects to be able to find it operational in
- `gnu_cc:[000000]gnu-as.exe'.
-
- To use GNU CC on VMS, you need the VMS driver programs `gcc.exe',
- `gcc.com', and `gcc.cld'. They are distributed with the VMS
- binaries (`gcc-vms') rather than the GNU CC sources. GAS is also
- included in `gcc-vms', as is Bison.
-
- Once you have successfully built GNU CC with VAX C, you should use
- the resulting compiler to rebuild itself. Before doing this, be
- sure to restore the `CC', `CFLAGS', and `LIBS' definitions in
- `make-cccp.com' and `make-cc1.com'. The second generation
- compiler will be able to take advantage of many optimizations that
- must be suppressed when building with other compilers.
-
- Under previous versions of GNU CC, the generated code would
-occasionally give strange results when linked with the sharable
-`VAXCRTL' library. Now this should work.
-
- Even with this version, however, GNU CC itself should not be linked
-with the sharable `VAXCRTL'. The version of `qsort' in `VAXCRTL' has a
-bug (known to be present in VMS versions V4.6 through V5.5) which
-causes the compiler to fail.
-
- The executables are generated by `make-cc1.com' and `make-cccp.com'
-use the object library version of `VAXCRTL' in order to make use of the
-`qsort' routine in `gcclib.olb'. If you wish to link the compiler
-executables with the shareable image version of `VAXCRTL', you should
-edit the file `tm.h' (created by `vmsconfig.com') to define the macro
-`QSORT_WORKAROUND'.
-
- `QSORT_WORKAROUND' is always defined when GNU CC is compiled with
-VAX C, to avoid a problem in case `gcclib.olb' is not yet available.
-
-`collect2'
-==========
-
- GNU CC uses a utility called `collect2' on nearly all systems to
-arrange to call various initialization functions at start time.
-
- The program `collect2' works by linking the program once and looking
-through the linker output file for symbols with particular names
-indicating they are constructor functions. If it finds any, it creates
-a new temporary `.c' file containing a table of them, compiles it, and
-links the program a second time including that file.
-
- The actual calls to the constructors are carried out by a subroutine
-called `__main', which is called (automatically) at the beginning of
-the body of `main' (provided `main' was compiled with GNU CC). Calling
-`__main' is necessary, even when compiling C code, to allow linking C
-and C++ object code together. (If you use `-nostdlib', you get an
-unresolved reference to `__main', since it's defined in the standard
-GCC library. Include `-lgcc' at the end of your compiler command line
-to resolve this reference.)
-
- The program `collect2' is installed as `ld' in the directory where
-the passes of the compiler are installed. When `collect2' needs to
-find the *real* `ld', it tries the following file names:
-
- * `real-ld' in the directories listed in the compiler's search
- directories.
-
- * `real-ld' in the directories listed in the environment variable
- `PATH'.
-
- * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
- if specified.
-
- * `ld' in the compiler's search directories, except that `collect2'
- will not execute itself recursively.
-
- * `ld' in `PATH'.
-
- "The compiler's search directories" means all the directories where
-`gcc' searches for passes of the compiler. This includes directories
-that you specify with `-B'.
-
- Cross-compilers search a little differently:
-
- * `real-ld' in the compiler's search directories.
-
- * `TARGET-real-ld' in `PATH'.
-
- * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
- if specified.
-
- * `ld' in the compiler's search directories.
-
- * `TARGET-ld' in `PATH'.
-
- `collect2' explicitly avoids running `ld' using the file name under
-which `collect2' itself was invoked. In fact, it remembers up a list
-of such names--in case one copy of `collect2' finds another copy (or
-version) of `collect2' installed as `ld' in a second place in the
-search path.
-
- `collect2' searches for the utilities `nm' and `strip' using the
-same algorithm as above for `ld'.
-
-Standard Header File Directories
-================================
-
- `GCC_INCLUDE_DIR' means the same thing for native and cross. It is
-where GNU CC stores its private include files, and also where GNU CC
-stores the fixed include files. A cross compiled GNU CC runs
-`fixincludes' on the header files in `$(tooldir)/include'. (If the
-cross compilation header files need to be fixed, they must be installed
-before GNU CC is built. If the cross compilation header files are
-already suitable for ANSI C and GNU CC, nothing special need be done).
-
- `GPLUSPLUS_INCLUDE_DIR' means the same thing for native and cross.
-It is where `g++' looks first for header files. The C++ library
-installs only target independent header files in that directory.
-
- `LOCAL_INCLUDE_DIR' is used only for a native compiler. It is
-normally `/usr/local/include'. GNU CC searches this directory so that
-users can install header files in `/usr/local/include'.
-
- `CROSS_INCLUDE_DIR' is used only for a cross compiler. GNU CC
-doesn't install anything there.
-
- `TOOL_INCLUDE_DIR' is used for both native and cross compilers. It
-is the place for other packages to install header files that GNU CC will
-use. For a cross-compiler, this is the equivalent of `/usr/include'.
-When you build a cross-compiler, `fixincludes' processes any header
-files in this directory.

-Installing GNU Fortran
-**********************
-
- The following information describes how to install `g77'.
-
- Note that, for users of the GCC-2.95 version of `g77', much of the
-information is obsolete, and is superceded by the GCC installation
-procedures. Such information is accordingly omitted and flagged as
-such.
-
- *Warning:* The information below is still under development, and
-might not accurately reflect the `g77' code base of which it is a part.
-Efforts are made to keep it somewhat up-to-date, but they are
-particularly concentrated on any version of this information that is
-distributed as part of a *released* `g77'.
-
- In particular, while this information is intended to apply to the
-GCC-2.95 version of `g77', only an official *release* of that version
-is expected to contain documentation that is most consistent with the
-`g77' product in that version.
-
- The following information was last updated on 1999-07-17:
-
-Prerequisites
-=============
-
- For users of the GCC-2.95 version of `g77', this information is
-superceded by the GCC installation instructions.
-
-Problems Installing
-===================
-
- This is a list of problems (and some apparent problems which don't
-really mean anything is wrong) that show up when configuring, building,
-installing, or porting GNU Fortran.
-
- *Note Installation Problems: (gcc)Installation Problems, for more
-information on installation problems that can afflict either `gcc' or
-`g77'.
-
-General Problems
-----------------
-
- These problems can occur on most or all systems.
-
-GNU C Required
-..............
-
- Compiling `g77' requires GNU C, not just ANSI C. Fixing this
-wouldn't be very hard (just tedious), but the code using GNU extensions
-to the C language is expected to be rewritten for 0.6 anyway, so there
-are no plans for an interim fix.
-
- This requirement does not mean you must already have `gcc' installed
-to build `g77'. As long as you have a working C compiler, you can use a
-"bootstrap" build to automate the process of first building `gcc' using
-the working C compiler you have, then building `g77' and rebuilding
-`gcc' using that just-built `gcc', and so on.
-
-Patching GNU CC
-...............
-
- `g77' no longer requires application of a patch file to the `gcc'
-compiler tree. In fact, no such patch file is distributed with `g77'.
-This is as of version 0.5.23 and `egcs' version 1.0.
-
-Building GNU CC Necessary
-.........................
-
- It should be possible to build the runtime without building `cc1'
-and other non-Fortran items, but, for now, an easy way to do that is
-not yet established.
-
-Missing strtoul or bsearch
-..........................
-
- This information does not apply to the GCC-2.95 version of `g77',
-
-Cleanup Kills Stage Directories
-...............................
-
- It'd be helpful if `g77''s `Makefile.in' or `Make-lang.in' would
-create the various `stageN' directories and their subdirectories, so
-developers and expert installers wouldn't have to reconfigure after
-cleaning up.
-
- That help has arrived as of version 0.5.23 of `g77' and version 1.1
-of `egcs'. Configuration itself no longer creates any particular
-directories that are unique to `g77'. The build procedures in
-`Make-lang.in' take care of that, on demand.
-
-LANGUAGES Macro Ignored
-.......................
-
- Prior to version 0.5.23 of `g77' and version 1.1 of `egcs', `g77'
-would sometimes ignore the absence of `f77' and `F77' in the
-`LANGUAGES' macro definition used for the `make' command being
-processed.
-
- As of `g77' version 0.5.23 and `egcs' version 1.1, `g77' now obeys
-this macro in all relevant situations.
-
- However, in versions of `gcc' through 2.8.1, non-`g77' portions of
-`gcc', such as `g++', are known to go ahead and perform various
-language-specific activities when their respective language strings do
-not appear in the `LANGUAGES' macro in effect during that invocation of
-`make'.
-
- It is expected that these remaining problems will be fixed in a
-future version of `gcc'.
-
-System-specific Problems
-------------------------
-
- A linker bug on some versions of AIX 4.1 might prevent building when
-`g77' is built within `gcc'. It might also occur when building within
-`egcs'.
-
-Cross-compiler Problems
------------------------
-
- `g77' has been in alpha testing since September of 1992, and in
-public beta testing since February of 1995. Alpha testing was done by
-a small number of people worldwide on a fairly wide variety of
-machines, involving self-compilation in most or all cases. Beta
-testing has been done primarily via self-compilation, but in more and
-more cases, cross-compilation (and "criss-cross compilation", where a
-version of a compiler is built on one machine to run on a second and
-generate code that runs on a third) has been tried and has succeeded,
-to varying extents.
-
- Generally, `g77' can be ported to any configuration to which `gcc',
-`f2c', and `libf2c' can be ported and made to work together, aside from
-the known problems described in this manual. If you want to port `g77'
-to a particular configuration, you should first make sure `gcc' and
-`libf2c' can be ported to that configuration before focusing on `g77',
-because `g77' is so dependent on them.
-
- Even for cases where `gcc' and `libf2c' work, you might run into
-problems with cross-compilation on certain machines, for several
-reasons.
-
- * There is one known bug (a design bug to be fixed in 0.6) that
- prevents configuration of `g77' as a cross-compiler in some cases,
- though there are assumptions made during configuration that
- probably make doing non-self-hosting builds a hassle, requiring
- manual intervention.
-
- * `gcc' might still have some trouble being configured for certain
- combinations of machines. For example, it might not know how to
- handle floating-point constants.
-
- * Improvements to the way `libg2c' is built could make building
- `g77' as a cross-compiler easier--for example, passing and using
- `$(LD)' and `$(AR)' in the appropriate ways. (This is improved in
- the `egcs' version of `g77', especially as of version 1.1.)
-
- * There are still some challenges putting together the right
- run-time libraries (needed by `libg2c') for a target system,
- depending on the systems involved in the configuration. (This is
- a general problem with cross-compilation, and with `gcc' in
- particular.)
-
-Changing Settings Before Building
-=================================
-
- Here are some internal `g77' settings that can be changed by editing
-source files in `egcs/gcc/f/' before building.
-
- This information, and perhaps even these settings, represent
-stop-gap solutions to problems people doing various ports of `g77' have
-encountered. As such, none of the following information is expected to
-be pertinent in future versions of `g77'.
-
-Larger File Unit Numbers
-------------------------
-
- As distributed, whether as part of `f2c' or `g77', `libf2c' accepts
-file unit numbers only in the range 0 through 99. For example, a
-statement such as `WRITE (UNIT=100)' causes a run-time crash in
-`libf2c', because the unit number, 100, is out of range.
-
- If you know that Fortran programs at your installation require the
-use of unit numbers higher than 99, you can change the value of the
-`MXUNIT' macro, which represents the maximum unit number, to an
-appropriately higher value.
-
- To do this, edit the file `egcs/libf2c/libI77/fio.h' in your `g77'
-source tree, changing the following line:
-
- #define MXUNIT 100
-
- Change the line so that the value of `MXUNIT' is defined to be at
-least one *greater* than the maximum unit number used by the Fortran
-programs on your system.
-
- (For example, a program that does `WRITE (UNIT=255)' would require
-`MXUNIT' set to at least 256 to avoid crashing.)
-
- Then build or rebuild `g77' as appropriate.
-
- *Note:* Changing this macro has *no* effect on other limits your
-system might place on the number of files open at the same time. That
-is, the macro might allow a program to do `WRITE (UNIT=100)', but the
-library and operating system underlying `libf2c' might disallow it if
-many other files have already been opened (via `OPEN' or implicitly via
-`READ', `WRITE', and so on). Information on how to increase these
-other limits should be found in your system's documentation.
-
-Always Flush Output
--------------------
-
- Some Fortran programs require output (writes) to be flushed to the
-operating system (under UNIX, via the `fflush()' library call) so that
-errors, such as disk full, are immediately flagged via the relevant
-`ERR=' and `IOSTAT=' mechanism, instead of such errors being flagged
-later as subsequent writes occur, forcing the previously written data
-to disk, or when the file is closed.
-
- Essentially, the difference can be viewed as synchronous error
-reporting (immediate flagging of errors during writes) versus
-asynchronous, or, more precisely, buffered error reporting (detection
-of errors might be delayed).
-
- `libg2c' supports flagging write errors immediately when it is built
-with the `ALWAYS_FLUSH' macro defined. This results in a `libg2c' that
-runs slower, sometimes quite a bit slower, under certain
-circumstances--for example, accessing files via the networked file
-system NFS--but the effect can be more reliable, robust file I/O.
-
- If you know that Fortran programs requiring this level of precision
-of error reporting are to be compiled using the version of `g77' you
-are building, you might wish to modify the `g77' source tree so that
-the version of `libg2c' is built with the `ALWAYS_FLUSH' macro defined,
-enabling this behavior.
-
- To do this, find this line in `egcs/libf2c/f2c.h' in your `g77'
-source tree:
-
- /* #define ALWAYS_FLUSH */
-
- Remove the leading `/* ', so the line begins with `#define', and the
-trailing ` */'.
-
- Then build or rebuild `g77' as appropriate.
-
-Maximum Stackable Size
-----------------------
-
- `g77', on most machines, puts many variables and arrays on the stack
-where possible, and can be configured (by changing
-`FFECOM_sizeMAXSTACKITEM' in `egcs/gcc/f/com.c') to force smaller-sized
-entities into static storage (saving on stack space) or permit
-larger-sized entities to be put on the stack (which can improve
-run-time performance, as it presents more opportunities for the GBE to
-optimize the generated code).
-
- *Note:* Putting more variables and arrays on the stack might cause
-problems due to system-dependent limits on stack size. Also, the value
-of `FFECOM_sizeMAXSTACKITEM' has no effect on automatic variables and
-arrays. *Note But-bugs::, for more information.
-
-Floating-point Bit Patterns
----------------------------
-
- The `g77' build will crash if an attempt is made to build it as a
-cross-compiler for a target when `g77' cannot reliably determine the
-bit pattern of floating-point constants for the target. Planned
-improvements for version 0.6 of `g77' will give it the capabilities it
-needs to not have to crash the build but rather generate correct code
-for the target. (Currently, `g77' would generate bad code under such
-circumstances if it didn't crash during the build, e.g. when compiling
-a source file that does something like `EQUIVALENCE (I,R)' and `DATA
-R/9.43578/'.)
-
-Initialization of Large Aggregate Areas
----------------------------------------
-
- A warning message is issued when `g77' sees code that provides
-initial values (e.g. via `DATA') to an aggregate area (`COMMON' or
-`EQUIVALENCE', or even a large enough array or `CHARACTER' variable)
-that is large enough to increase `g77''s compile time by roughly a
-factor of 10.
-
- This size currently is quite small, since `g77' currently has a
-known bug requiring too much memory and time to handle such cases. In
-`egcs/gcc/f/data.c', the macro `FFEDATA_sizeTOO_BIG_INIT_' is defined
-to the minimum size for the warning to appear. The size is specified
-in storage units, which can be bytes, words, or whatever, on a
-case-by-case basis.
-
- After changing this macro definition, you must (of course) rebuild
-and reinstall `g77' for the change to take effect.
-
- Note that, as of version 0.5.18, improvements have reduced the scope
-of the problem for *sparse* initialization of large arrays, especially
-those with large, contiguous uninitialized areas. However, the warning
-is issued at a point prior to when `g77' knows whether the
-initialization is sparse, and delaying the warning could mean it is
-produced too late to be helpful.
-
- Therefore, the macro definition should not be adjusted to reflect
-sparse cases. Instead, adjust it to generate the warning when densely
-initialized arrays begin to cause responses noticeably slower than
-linear performance would suggest.
-
-Alpha Problems Fixed
---------------------
-
- `g77' used to warn when it was used to compile Fortran code for a
-target configuration that is not basically a 32-bit machine (such as an
-Alpha, which is a 64-bit machine, especially if it has a 64-bit
-operating system running on it). That was because `g77' was known to
-not work properly on such configurations.
-
- As of version 0.5.20, `g77' is believed to work well enough on such
-systems. So, the warning is no longer needed or provided.
-
- However, support for 64-bit systems, especially in areas such as
-cross-compilation and handling of intrinsics, is still incomplete. The
-symptoms are believed to be compile-time diagnostics rather than the
-generation of bad code. It is hoped that version 0.6 will completely
-support 64-bit systems.
