Following those steps, my app started just fine on Snow Leopard. Thank you
Emanuele!
I would, however, like to understand this problem a bit more so I can fix
the build. I'd like this app to run out of the box.
Looking at ft2font.so:
otool -L Resources/lib/python2.5/matplotlib/ft2font.so
Resources/lib/python2.5/matplotlib/ft2font.so:
@executable_path/../Frameworks/libfreetype.6.dylib (compatibility
version 10.0.0, current version 10.12.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version
1.2.3)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current
version 7.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.3)
@executable_path/../Frameworks/libgcc_s.1.dylib (compatibility
version 1.0.0, current version 1.0.0)
For matplotlib to load successfully, which libgcc should be loaded?
Thanks again,
BZ
