Default gcc on Snow Leopard is 4.2, which does not work with the 10.4 SDK.
When we discussed this before you thought that my SDK was broken, but that
is not the case. It is linked to http://bugs.python.org/issue6957. That
issue was closed but not actually resolved - just ignored because python
itself is still built on OS X 10.5. There are bug reports and threads for
many python extensions about this issue.
The "$ export CC=/usr/bin/gcc-4.0" is unnecessary by the way (gcc-4.0 is
picked up by default cause that's what python is built with), but "$ export
CXX=/usr/bin/c++-4.0" is needed. c++-4.2 and 10.4SDK are not compatible.
Unless I'm misunderstanding the problem, we can either:
- decide the N_GSYM thing is not an issue
- build against 10.5 or 10.6 SDK, which requires changes to distutils.
- build the binaries on 10.5 (Leopard). But I don't have that available.
