[PySide] shiboken build issue with PythonLibs

[Amos Anderson]

Hello PySide list!

I'm trying to compile PySide on an OSX 10.6 machine, but I run into a problem where shiboken is linking to a python symbol __PyTrash_thread_deposit_object which doesn't exist in the local python it's supposed to be linking against (the symbol __PyTrash_deposit_object exists there instead, c.f. the text pasted below). That is, I'm storing a version of python in a project directory, and shiboken is supposed to link against that, but it appears to be linking against the python in /Library/Frameworks/Python.framework (which has extra symbols that my project python does not have). The environment.sh script is finding my python, and my python's libraries are on DYLD_LIBRARY_PATH, but shiboken and/or cmake seem to be ignoring them. The build works if I delete my python from /Library/Frameworks/Python.framework.

I even tried adding:
-DPYTHON_LIBRARY=/Users/amosa/triad/tools/python/lib/libpython2.7.dylib -DPYTHON_INCLUDE=/Users/amosa/triad/tools/python/include
to the cmake command in build_and_install, but that didn't help. it printed:
-- Found PythonLibs: /Users/amosa/triad/tools/python/lib/libpython2.7.dylib (found suitable version "2.7.5", minimum required is "2.6") 
-- Found PythonInterp: /Users/amosa/triad/tools/python/bin/python2.7 (found version "2.7.3")
I can't explain the version discrepancy (my Frameworks version is 2.7.5, my local version is 2.7.3)

I'm using cmake 2.8.10.1

So anyway, I have a solution available, but it's a hack... it would be nice to know if there's a way available that's less of a hack. Any suggestions?

Thanks!
Amos.
