Thank you,
now I got one step further.
The only issue that remains is when i import myextension
the libboost_python-1_33_1.dylib on which it depends is not found.
Also i set up the DYLD_LIBRARY_PATH accordingly or is this the
wrong place? sorry, if i might miss some OS X special again.
ImportError: Failure linking new module: myextension.so: Library not
loaded: libboost_python-1_33_1.dylib
Referenced from: myextension.so
Reason: image not found
echo $DYLD_LIBRARY_PATH
:/Users/nies/src/boost_1_33_1/bin/boost/libs/python/build/libboost_python.dylib/darwin/debug/shared-linkable-true/
otool -L myextension.so
myextension.so:
/Library/Frameworks/Python.framework/Versions/2.4/Python
(compatibility version 2.4.0, current version 2.4.0)
/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL
(compatibility version 1.0.0, current version 1.0.0)
/System/Library/Frameworks/GLUT.framework/Versions/A/GLUT
(compatibility version 1.0.0, current version 1.0.0)
libboost_python-1_33_1.dylib (compatibility version 0.0.0,
current version 0.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0,
current version 7.4.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.1.7)
But many Thanks Thorsten,
Vielen Dank,
Stephan
