Re: Supporting --enable-version-specific-runtime-libs

[Benjamin Kosnik <bkoz at redhat dot com>]

err. I put a modified version of your patch in CVS on Saturday.

2000-10-13  Benjamin Kosnik  <bkoz@purist.soma.redhat.com>
            Mark Harig  <markh@landmark.com>

        * src/Makefile.am (toolexeclibdir): Add support fo
        VERSION_SPECIFIC_LIBS and --with-gxx-include-dir.
        * src/Makefile.in: Regenerate.
        * libsupc++/Makefile.am: Same.
        (glibcppinstalldir): Adjust.
        * libsupc++/Makefile.in: Regenerate.
        * Makefile.am: Remove gxx_include_dir. Remove INCLUDE. 
        * Makefile.in: Regenerate.
        * docs/configopts.html: Add descriptions of flags.

You might want to check out current CVS.

I already fixed this bit with the installation routines:

In addition, I kept USE_LIBDIR just because I didn't want libstdc++ 
divergence with what is apparently a common idiom in makefile/configure 
scripts across the development toolchain (ie gcc/java/c++).

The resulting bits in src/Makefile.am look like:

# Cross compiler and multilib support.
# Install a library built with a cross compiler in tooldir, not libdir.
if USE_LIBDIR
toolexeclibdir = $(libdir)$(MULTISUBDIR)
else
if VERSION_SPECIFIC_LIBS
gcc_version = @gcc_version@
toolexecdir = $(libdir)/gcc-lib/$(target_alias)
toolexeclibdir = $(toolexecdir)/$(gcc_version)
else
toolexecdir = $(exec_prefix)/$(target_alias)
toolexeclibdir = $(toolexecdir)/lib$(MULTISUBDIR)
endif
endif


I will check in your version of the docs though.

Thanks again for all your hard work
