README
This directory contains the -liberty library of free software. It is a collection of subroutines used by various GNU programs. Current members include: getopt -- get options from command line obstack -- stacks of arbitrarily-sized objects strerror -- error message strings corresponding to errno strtol -- string-to-long conversion strtoul -- string-to-unsigned-long conversion We expect many of the GNU subroutines that are floating around to eventually arrive here. The library must be configured from the top source directory. Don't try to run configure in this directory. Follow the configuration instructions in ../README. Please report bugs to "gcc-bugs@gcc.gnu.org" and send fixes to "gcc-patches@gcc.gnu.org". Thank you. ADDING A NEW FILE ================= There are two sets of files: Those that are "required" will be included in the library for all configurations, while those that are "optional" will be included in the library only if "needed." To add a new required file, edit Makefile.in to add the source file name to CFILES and the object file to REQUIRED_OFILES. To add a new optional file, it must provide a single function, and the name of the function must be the same as the name of the file. * Add the source file name to CFILES in Makefile.in and the object file to CONFIGURED_OFILES. * Add the function to name to the funcs shell variable in configure.ac. * Add the function to the AC_CHECK_FUNCS lists just after the setting of the funcs shell variable. These AC_CHECK_FUNCS calls are never executed; they are there to make autoheader work better. * Consider the special cases of building libiberty; as of this writing, the special cases are newlib and VxWorks. If a particular special case provides the function, you do not need to do anything. If it does not provide the function, add the object file to LIBOBJS, and add the function name to the case controlling whether to define HAVE_func. Finally, in the build directory of libiberty, configure with "--enable-maintainer-mode", run "make maint-deps" to update Makefile.in, and run 'make stamp-functions' to regenerate functions.texi. The optional file you've added (e.g. getcwd.c) should compile and work on all hosts where it is needed. It does not have to work or even compile on hosts where it is not needed. ADDING A NEW CONFIGURATION ========================== On most hosts you should be able to use the scheme for automatically figuring out which files are needed. In that case, you probably don't need a special Makefile stub for that configuration. If the fully automatic scheme doesn't work, you may be able to get by with defining EXTRA_OFILES in your Makefile stub. This is a list of object file names that should be treated as required for this configuration - they will be included in libiberty.a, regardless of whatever might be in the C library.
