It is distributed with other "binary -utilities" which should be in ../binutils. See ../binutils/README for -more general notes, including where to send bug reports. - -There are many features of the linker: - -* The linker uses a Binary File Descriptor library (../bfd) - that it uses to read and write object files. This helps - insulate the linker itself from the format of object files. - -* The linker supports a number of different object file - formats. It can even handle multiple formats at once: - Read two input formats and write a third. - -* The linker can be configured for cross-linking. - -* The linker supports a control language. - -* There is a user manual (ld.texinfo), as well as the - beginnings of an internals manual (ldint.texinfo). - -Installation -============ - -See ../binutils/README. - -If you want to make a cross-linker, you may want to specify -a different search path of -lfoo libraries than the default. -You can do this by setting the LIB_PATH variable in ./Makefile. - -To build just the linker, make the target all-ld from the top level -directory (one directory above this one). - -Porting to a new target -======================= - -See the ldint.texinfo manual. - -Reporting bugs etc -=========================== - -See ../binutils/README. - -Known problems -============== - -The Solaris linker normally exports all dynamic symbols from an -executable. The GNU linker does not do this by default. This is -because the GNU linker tries to present the same interface for all -similar targets (in this case, all native ELF targets). This does not -matter for normal programs, but it can make a difference for programs -which try to dlopen an executable, such as PERL or Tcl. You can make -the GNU linker export all dynamic symbols with the -E or ---export-dynamic command line option. - -HP/UX 9.01 has a shell bug that causes the linker scripts to be -generated incorrectly. The symptom of this appears to be "fatal error -- scanner input buffer overflow" error messages. There are various -workarounds to this: - * Build and install bash, and build with "make SHELL=bash". - * Update to a version of HP/UX with a working shell (e.g., 9.05). - * Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in - genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the - emulparams script used exports any shell variables it sets. |
