|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 "firstname.lastname@example.org" and send fixes to
|"email@example.com". 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
| * 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
| * 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
|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.
