FWIW, all three python installations I have handy (2.7 on Fedora 14, 2.7 on OS X Lion, 2.5 on HPUX) produce the same result from either of python -c "from distutils.sysconfig import get_python_lib as f; import os; print(os.path.join(f(plat_specific=1,standard_lib=1),'config'))" python -c "import distutils.sysconfig,string; print(' '.join(filter(None,distutils.sysconfig.get_config_vars('LIBPL'))))" It's not immediately apparent to me why we should think that get_python_lib is less trustworthy than LIBPL; but if someone can make that case, I don't have any objection to this part of the patch. >> 2.

Yes. In particular, this appears to be doing the wrong thing on my Lion installation: it changes python_libspec = -L/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -lpython2.7 to just python_libspec = -L/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -lpython and there is no libpython.dylib in that directory. The build accidentally fails to fail because there is a libpython.dylib in /usr/lib and it happens to be symlinked to the right version of python, but I hardly think we want to trust that. I'm also wondering why a patch that's supposed to enable building against python 3.2 should need to touch the "old way" code path. If 3.2 isn't using the "new way", what exactly does? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
