Artificial libpython3.2.a soft links to libpython3.2m.a

Sorry, can you explain better what problem you are seeing including specific error messages?

Use the Mac OS 10.7 compiler uWSGI Makefile.Py32 (make-f), will report a compile error. Information in the annex.Artificially will the soft libpython3.2.a / Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/config-3.2m under connection to a libpython3.2m.a, the problem-solving.

Thank you for the additional information. It appears the problem is that, for OS X framework builds, the ABI suffix (added in PEP-3149) is not used to create the shared library dylib name in the framework lib directory. For example,

$ cd Library/Frameworks/Python.framework/Versions/3.2
$ ./bin/python3.2-config --libs
-ldl -framework CoreFoundation -lpython3.2m
$ ls -l ./lib
total 8
lrwxr-xr-x   1 root  wheel     9 Feb 24 09:44 libpython3.2.dylib@ -> ../Python
drwxrwxr-x   2 root  admin   170 Feb 24 08:49 pkgconfig/
drwxrwxr-x  32 root  admin  6290 Feb 24 08:49 python3.2/

But in an --enable-shared --with-pydebug build:

$ ./bin/python3.2-config --libs
-ldl -framework CoreFoundation -lpython3.2dm
$ ls -l ./lib
total 6920
-r-xr-xr-x   1 nad  pyd  3541320 Mar  4 23:40 libpython3.2dm.dylib*
drwxr-xr-x   2 nad  pyd      170 Mar  4 23:40 pkgconfig/
drwxr-xr-x  32 nad  pyd     6290 Mar  4 23:40 python3.2/

Looks like target frameworkinstallmaclib in Makefile.pre.in needs to be changed to include SOABI in the name for the lib symlink.

The attached patch ensures that additional SOABI-suffixed symlinks are created in the framework lib and lib/pythonx.x/config-yy directories and fixes pythons.x-config to not return garbage data for the --ldflags option.

Georg, I'd like to apply this for both 3.2.4 and 3.3.0b2. It's a low risk bug fix but does solve a real problem for users wanting to embed Python on OS X. bpo-15353 is also fixed by this.
