Summary: ctypes extension does not compile on Mac OS 10.3.9
Initial Comment:
I compiled Python from CVS this morning. It silently failed to compile
ctypes. Here is the text surrounding the failure
gcc [deleted] -c /Users/dalke/cvses/python-svn/Modules/_ctypes/
libffi/src/powerpc/darwin_closure.S -o build/temp.darwin-7.9.0-
Power_Macintosh-2.5/darwin_closure.o
darwin_closure.S:249:unknown section attribute: live_support
darwin_closure.S:249:Rest of line ignored. 1st junk character valued 69
(E).
building 'itertools' extension
...
Python installed but when I tried to import ctypes I got
File "/usr/local/lib/python2.5/ctypes/__init__.py", line 8, in
<module>
from _ctypes import Union, Structure, Array
ImportError: No module named _ctypes
I tracked it down to the '+live_support' attribute from the
darwin_closure.S. My compiler does not understand that.
Thomas Heller (in private email) pointed out the text from the ctypes
README
On OS X, the segment attribute live_support must be
defined. If your compiler doesn't know about it, upgrade or
set the environment variable CCASFLAGS="-Dno_live_support".
Upgrading is out of the option. I set the environment variable but that
did not fix things when I tried to recompile Python. However, editing
the file to remove the "+live_support" works. All the self-tests passed,
and my experimentation this afternoon was successful.

As a temporary fix, I removed the '+live_support' attribute
in the source file. Andrew, can you please verify that this
works for you?
Thanks, Thomas
