Summary: OS X framework build for python 2.5 fails, configure is odd

Initial Comment:
The OS X framework build for python 2.5 does not install a dynamic 
library at /Library/Frameworks/Python.framework/Versions/2.5/Python 
where it should. The python2.5 executible does not run because it is 
trying to load this dynamic library.

This is on an intel mac with darwin-8.6.1 and gcc4 and python2.5a2.

Also all of the extra modules (_CG extension, IDLE extra) fail to link 
because their link command is -lpython2.5 which is not what it should be 
for a framework build and even if it was correct for linking agianst a 
framework it would fil because the framework doesn't have its library 
anyway.

Finally, the configure script behaves oddly in that it works fine, but if you 
change the parameters and rerun it it will fail unless you run 'make 
distclean'

This is where it fails.

checking whether mmap with MAP_ANON(YMOUS) works... yes
configure: error: "libffi has not been ported to i686-apple-darwin8.6.1."
Failed to configure _ctypes module

I've checked in a fix in revision 46103. Could you please test if this solves the 
problems for you?

I'm currently building the trunk and I'm seeing the same issue as you. The 
problem is caused by the checkin at revision 45232 by Martin van Loewis. This 
forces '-lpython2.5' onto the commandline for the linker when building 
extensions.

I'm working on a patch that disables this feature for framework builds.

The configure failure in the orginal message is not a problem, that's libffi failing. 
Libffi is used by ctypes and not supported on darwin/x86. I have a patch and I 
know of another one, but neither have been merged into the copy that's used by 
ctypes. The only effect of this is that you won't get ctypes.

Could you test  again without --enable-profiling? That's one flag I've never used 
and didn't test yet. BTW. the attached build log contains lots of NUL bytes, 
should it or has it been corrupted along the way?

Hi Neal,

I checked out rev 46003 (the HEAD at the time) in a clean directory and used: 

./configure --enable-profiling --enable-shared --enable-framework --
enable-universalsdk

Unfortunately it failed in the same way it has the same problems in that it is 
linking with the flag -lpython2.5 when it should be a framework linking. I 
have attached the build log from after having built it once so you only see the 
linking.

However, it does appear that the issue raised in bug # 1487105 is solved. It 
compiled fine on an intel mac it just has linking problems.

Also I get exactly the same problem on a G5

Chris

Christopher can you try with a current checkout?  Ronald
checked in lots of changes which I think include x86 support
at svn rev 45997.
