Hi,
I think it is time to fix libsoname for libstdc++ once for all. The
current scheme is not working. We should fix it for egcs 1.1. I
propose we do the following:
1. Like glibc 2, the real shared libstdc++ file has name,
libstdc++-ABI-version-reversion.so. Its soname is a symlink from
libstdc++-ABI-version-reversion.so to libstdc++-ABI.so.version.
They are installed in $(libdir)
2. The static libstc++.a is installed in $(libsubdir) along with
a symlink from $(libdir)/libstdc++-ABI.so.version to libstc++.so.
The reason we need libstdc++-ABI-version-reversion.so instead of
libstdc++-version-reversion.so is on some systems, like Linux,
you can have shared libstdc++ libraries with different ABIs, but
the same version of libstdc++, at the same time. We can have a
default ABI name, like egcs-1.0 or egcs-1.1. On Linux, we can use
egcs-1.1-libc5, egcs-1.1-glibc2.0 and egcs-1.1-glibc2.1.
3. The C++ header files should go into ${prefix}/include/g++-API.
Here I made a differennce between API and ABI. We may have multiple
ABIs, but only one API on Linux.
It will make everyone happy including gcc 2.8.1. I can supply a patch
for it.
Thanks.
