Issue 1447587: Mac Framework build fails on intel (original) (raw)

hardware: intel duo imac 20" os x: 10.4.6

steps:

./configure --enable-framework=/Library/Frameworks/Python.framework --enable-shared make ... c++ -u _PyMac_Error Python.framework/Versions/2.4/Python -o python.exe
Modules/python.o
-ldl
/usr/bin/ld: warning Python.framework/Versions/2.4/Python cputype (18, architecture ppc) does not match cputype (7) for specified -arch flag: i386 (file not loaded) /usr/bin/ld: Undefined symbols: _PyMac_Error _Py_Main collect2: ld returned 1 exit status make: *** [python.exe] Error 1

analysis:

The arch flag for the Python shared library in the framework is incorrect.

file shows Python.framework/Versions/2.4/Python to be a PPC binary.

scroll up in terminal to find link statement for Python:

libtool -o Python.framework/Versions/2.4/Python -dynamic libpython2.4.a
-lSystem -lSystemStubs -arch_only ppc -install_name /Library/Frameworks/Python.framework/Python.framework/Versions/2.4/Python -compatibility_version 2.4 -current_version 2.4

The '-arch_only ppc' flag is the problem.

workaround:

After running configure, open makefile and so a s/arch_only ppc/arch_only i386/g

what needs to be fixed:

Around line 10218 in configure: Darwin/[01234567].) LIBTOOL_CRUFT="-framework System -lcc_dynamic -arch_only ppc"
