Python runtime_library_dirs doesn't work on Mac

Question

I have a Python extension module that needs to link against some dynamic libraries at runtime, so I need to tell it where to look for them. I\'m doing this by specifying ru

Answer 1

You can tell what libraries an extension links against with

otool -L pyext.so

I had a problem where an extension was linking to the wrong version of a library on my system. In that case I used install_name_tool to change the path to the library directly. For example,

install_name_tool -change /wrong/libfoo.dylib /right/libfoo.dylib pyext.so
