By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes some time. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile readline and build the static readline - and history libraries. If supported, the shared readline and history - libraries will be built also. See below for instructions on compiling - the other parts of the distribution. Typing `make everything' will - cause the static and shared libraries (if supported) and the example - programs to be built. - - 3. Type `make install' to install the static readline and history - libraries, the readline include files, the documentation, and, if - supported, the shared readline and history libraries. - - 4. You can remove the created libraries and object files from the - build directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile readline for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the readline developers, and should be used with care. - -The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It -uses those values to create a `Makefile' in the build directory, -and Makefiles in the `doc', `shlib', and `examples' -subdirectories. It also creates a `config.h' file containing -system-dependent definitions. Finally, it creates a shell script -`config.status' that you can run in the future to recreate the -current configuration, a file `config.cache' that saves the -results of its tests to speed up reconfiguring, and a file -`config.log' containing compiler output (useful mainly for -debugging `configure'). - -If you need to do unusual things to compile readline, please try -to figure out how `configure' could check whether to do them, and -mail diffs or instructions to <bug-readline@gnu.org> so they can -be considered for the next release. If at some point -`config.cache' contains results you don't want to keep, you may -remove or edit it. - -The file `configure.in' is used to create `configure' by a -program called `autoconf'. You only need `configure.in' if you -want to change it or regenerate `configure' using a newer version -of `autoconf'. The readline `configure.in' requires autoconf -version 2.50 or newer. - -Compilers and Options -===================== - -Some systems require unusual options for compilation or linking that -the `configure' script does not know about. You can give `configure' -initial values for variables by setting them in the environment. Using -a Bourne-compatible shell, you can do that on the command line like -this: - - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure - -Or on systems that have the `env' program, you can do it like this: - - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure - -Compiling For Multiple Architectures -==================================== - -You can compile readline for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - -If you have to use a `make' that does not supports the `VPATH' -variable, you have to compile readline for one architecture at a -time in the source code directory. After you have installed -readline for one architecture, use `make distclean' before -reconfiguring for another architecture. - -Installation Names -================== - -By default, `make install' will install the readline libraries in -`/usr/local/lib', the include files in -`/usr/local/include/readline', the man pages in `/usr/local/man', -and the info files in `/usr/local/info'. You can specify an -installation prefix other than `/usr/local' by giving `configure' -the option `--prefix=PATH' or by supplying a value for the -DESTDIR variable when running `make install'. - -You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. -If you give `configure' the option `--exec-prefix=PATH', the -readline Makefiles will use PATH as the prefix for installing the -libraries. Documentation and other data files will still use the -regular prefix. - -Specifying the System Type -========================== - -There may be some features `configure' can not figure out -automatically, but need to determine by the type of host readline -will run on. Usually `configure' can figure that out, but if it -prints a message saying it can not guess the host type, give it -the `--host=TYPE' option. TYPE can either be a short name for -the system type, such as `sun4', or a canonical name with three -fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). - -See the file `config.sub' for the possible values of each field. - -Sharing Defaults -================ - -If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: the readline `configure' looks for a site script, but not -all `configure' scripts do. - -Operation Controls -================== - -`configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--version' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`configure' also accepts some other, not widely useful, options. - -Optional Features -================= - -The readline `configure' recognizes a single `--with-PACKAGE' option: - -`--with-curses' - This tells readline that it can find the termcap library functions - (tgetent, et al.) in the curses library, rather than a separate - termcap library. Readline uses the termcap functions, but does not - link with the termcap or curses library itself, allowing applications - which link with readline the to choose an appropriate library. - This option tells readline to link the example programs with the - curses library rather than libtermcap. - -`configure' also recognizes two `--enable-FEATURE' options: - -`--enable-shared' - Build the shared libraries by default on supported platforms. The - default is `yes'. - -`--enable-static' - Build the static libraries by default. The default is `yes'. - -Shared Libraries -================ - -There is support for building shared versions of the readline and -history libraries. The configure script creates a Makefile in -the `shlib' subdirectory, and typing `make shared' will cause -shared versions of the readline and history libraries to be built -on supported platforms. - -If `configure' is given the `--enable-shared' option, it will attempt -to build the shared libraries by default on supported platforms. - -Configure calls the script support/shobj-conf to test whether or -not shared library creation is supported and to generate the values -of variables that are substituted into shlib/Makefile. If you -try to build shared libraries on an unsupported platform, `make' -will display a message asking you to update support/shobj-conf for -your platform. - -If you need to update support/shobj-conf, you will need to create -a `stanza' for your operating system and compiler. The script uses -the value of host_os and ${CC} as determined by configure. For -instance, FreeBSD 4.2 with any version of gcc is identified as -`freebsd4.2-gcc*'. - -In the stanza for your operating system-compiler pair, you will need to -define several variables. They are: - -SHOBJ_CC The C compiler used to compile source files into shareable - object files. This is normally set to the value of ${CC} - by configure, and should not need to be changed. - -SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create - position-independent code. If you are using gcc, this - should probably be set to `-fpic'. - -SHOBJ_LD The link editor to be used to create the shared library from - the object files created by $SHOBJ_CC. If you are using - gcc, a value of `gcc' will probably work. - -SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. - If you are using gcc, `-shared' may be all that is necessary. - These should be the flags needed for generic shared object - creation. - -SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library - creation. Many systems use the -R option to the link - editor to embed a path within the library for run-time - library searches. A reasonable value for such systems would - be `-R$(libdir)'. - -SHLIB_LIBS Any additional libraries that shared libraries should be - linked against when they are created. - -SHLIB_LIBPREF The prefix to use when generating the filename of the shared - library. The default is `lib'; Cygwin uses `cyg'. - -SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when - generating the filename of the shared library. Many systems - use `so'; HP-UX uses `sl'. - -SHLIB_LIBVERSION The string to append to the filename to indicate the version - of the shared library. It should begin with $(SHLIB_LIBSUFF), - and possibly include version information that allows the - run-time loader to load the version of the shared library - appropriate for a particular program. Systems using shared - libraries similar to SunOS 4.x use major and minor library - version numbers; for those systems a value of - `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. - Systems based on System V Release 4 don't use minor version - numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. - Other Unix versions use different schemes. - -SHLIB_DLLVERSION The version number for shared libraries that determines API - compatibility between readline versions and the underlying - system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but - can be overridden at configuration time by defining DLLVERSION - in the environment. - -SHLIB_DOT The character used to separate the name of the shared library - from the suffix and version information. The default is `.'; - systems like Cygwin which don't separate version information - from the library name should set this to the empty string. - -SHLIB_STATUS Set this to `supported' when you have defined the other - necessary variables. Make uses this to determine whether - or not shared library creation should be attempted. If - shared libraries are not supported, this will be set to - `unsupported'. - -You should look at the existing stanzas in support/shobj-conf for ideas. - -Once you have updated support/shobj-conf, re-run configure and type -`make shared' or `make'. The shared libraries will be created in the -shlib subdirectory. - -If shared libraries are created, `make install' will install them. -You may install only the shared libraries by running `make -install-shared' from the top-level build directory. Running `make -install' in the shlib subdirectory will also work. If you don't want -to install any created shared libraries, run `make install-static'. diff --git a/cmd-line-utils/readline/README b/cmd-line-utils/readline/README deleted file mode 100644 index 8da99626aa1..00000000000 --- a/cmd-line-utils/readline/README +++ /dev/null @@ -1,186 +0,0 @@ -Introduction -============ - -This is the Gnu Readline library, version 5.2. - -The Readline library provides a set of functions for use by applications -that allow users to edit command lines as they are typed in.

If you are not, the following -may work: - - env CC=cc ./configure - -Read the file INSTALL in this directory for more information about how -to customize and control the build process. - -The file rlconf.h contains C preprocessor defines that enable and disable -certain Readline features. - -The special make target `everything' will build the static and shared -libraries (if the target platform supports them) and the examples. - -Examples -======== - -There are several example programs that use Readline features in the -examples directory. The `rl' program is of particular interest. It -is a command-line interface to Readline, suitable for use in shell -scripts in place of `read'. - -Shared Libraries -================ - -There is skeletal support for building shared versions of the -Readline and History libraries. The configure script creates -a Makefile in the `shlib' subdirectory, and typing `make shared' -will cause shared versions of the Readline and History libraries -to be built on supported platforms. - -If `configure' is given the `--enable-shared' option, it will attempt -to build the shared libraries by default on supported platforms. - -Configure calls the script support/shobj-conf to test whether or -not shared library creation is supported and to generate the values -of variables that are substituted into shlib/Makefile. If you -try to build shared libraries on an unsupported platform, `make' -will display a message asking you to update support/shobj-conf for -your platform. - -If you need to update support/shobj-conf, you will need to create -a `stanza' for your operating system and compiler. The script uses -the value of host_os and ${CC} as determined by configure. For -instance, FreeBSD 4.2 with any version of gcc is identified as -`freebsd4.2-gcc*'. - -In the stanza for your operating system-compiler pair, you will need to -define several variables. They are: - -SHOBJ_CC The C compiler used to compile source files into shareable - object files. This is normally set to the value of ${CC} - by configure, and should not need to be changed. - -SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create - position-independent code. If you are using gcc, this - should probably be set to `-fpic'. - -SHOBJ_LD The link editor to be used to create the shared library from - the object files created by $SHOBJ_CC. If you are using - gcc, a value of `gcc' will probably work. - -SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. - If you are using gcc, `-shared' may be all that is necessary. - These should be the flags needed for generic shared object - creation. - -SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library - creation. Many systems use the -R option to the link - editor to embed a path within the library for run-time - library searches. A reasonable value for such systems would - be `-R$(libdir)'. - -SHLIB_LIBS Any additional libraries that shared libraries should be - linked against when they are created. - -SHLIB_LIBPREF The prefix to use when generating the filename of the shared - library. The default is `lib'; Cygwin uses `cyg'. - -SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when - generating the filename of the shared library. Many systems - use `so'; HP-UX uses `sl'. - -SHLIB_LIBVERSION The string to append to the filename to indicate the version - of the shared library. It should begin with $(SHLIB_LIBSUFF), - and possibly include version information that allows the - run-time loader to load the version of the shared library - appropriate for a particular program. Systems using shared - libraries similar to SunOS 4.x use major and minor library - version numbers; for those systems a value of - `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. - Systems based on System V Release 4 don't use minor version - numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. - Other Unix versions use different schemes. - -SHLIB_DLLVERSION The version number for shared libraries that determines API - compatibility between readline versions and the underlying - system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but - can be overridden at configuration time by defining DLLVERSION - in the environment. - -SHLIB_DOT The character used to separate the name of the shared library - from the suffix and version information. The default is `.'; - systems like Cygwin which don't separate version information - from the library name should set this to the empty string. - -SHLIB_STATUS Set this to `supported' when you have defined the other - necessary variables. Make uses this to determine whether - or not shared library creation should be attempted. - -You should look at the existing stanzas in support/shobj-conf for ideas. - -Once you have updated support/shobj-conf, re-run configure and type -`make shared'. The shared libraries will be created in the shlib -subdirectory. - -If shared libraries are created, `make install' will install them. -You may install only the shared libraries by running `make -install-shared' from the top-level build directory. Running `make -install' in the shlib subdirectory will also work. If you don't want -to install any created shared libraries, run `make install-static'. - -Documentation -============= - -The documentation for the Readline and History libraries appears in -the `doc' subdirectory. There are three texinfo files and a -Unix-style manual page describing the facilities available in the -Readline library. The texinfo files include both user and -programmer's manuals. HTML versions of the manuals appear in the -`doc' subdirectory as well. - -Reporting Bugs -============== - -Bug reports for Readline should be sent to: - - bug-readline@gnu.org - -When reporting a bug, please include the following information: - - * the version number and release status of Readline (e.g., 4.2-release) - * the machine and OS that it is running on - * a list of the compilation flags or the contents of `config.h', if - appropriate - * a description of the bug - * a recipe for recreating the bug reliably - * a fix for the bug if you have one! - -If you would like to contact the Readline maintainer directly, send mail -to bash-maintainers@gnu.org. - -Since Readline is developed along with bash, the bug-bash@gnu.org mailing -list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains -Readline bug reports and fixes. - -Chet Ramey -chet.ramey@case.edu diff --git a/cmd-line-utils/readline/ansi_stdlib.h b/cmd-line-utils/readline/ansi_stdlib.h deleted file mode 100644 index 42ac66ebcc0..00000000000 --- a/cmd-line-utils/readline/ansi_stdlib.h +++ /dev/null @@ -1,54 +0,0 @@ -/* ansi_stdlib.h -- An ANSI Standard stdlib.h. */ -/* A minimal stdlib.h containing extern declarations for those functions - that bash uses. */ - -/* Copyright (C) 1993 Free Software Foundation, Inc. - - This file is part of GNU Bash, the Bourne Again SHell. - - Bash is free software; you can redistribute it and/or modify it under - the terms of the GNU General Public License as published by the Free - Software Foundation; either version 2, or (at your option) any later - version. - - Bash is distributed in the hope that it will be useful, but WITHOUT ANY - WARRANTY; without even the implied warranty of MERCHANTABILITY or - FITNESS FOR A PARTICULAR PURPOSE.
