Summary: --enable-shared links extensions to libpython statically

Initial Comment:
python 2.5 tries to link extension modules to libpython2.5 if python is compiled with --enable-shared (patch #1429775, bug #83279, svn r45232). To do this it adds -lpython2.5 and -L$PREFIX/lib/python2.5/config to the link command line. -lpython2.5 is fine, however the "config" directory it adds contains a static libpython2.5.a library. The libpython2.5.so I think it should be linking to is in $PREFIX/lib. The result is even a trivial extension pulls in (nearly) all of that library, so you get an extension that is over a megabyte in size where older pythons produce one of a few kilobytes.

There is a comment on the referenced bug saying

"""
You can probably rely on libpythonxy.so ending up in
$(DESTDIR)$(LIBDIR)/$(INSTSONAME), whose values you can
retrieve from the installed Makefile (i.e. through
distutils.config).
"""

so I think the patch that got applied does not do what was intended.

I can't reproduce the problem. Why do you think
-L$PREFIX/lib/python2.5/config is added to the link command line? AFAICT,
it never is.

What operating system are you using?
