Trying to load a shared lib out of the current ‘.’ dir in a unit test on osx.

What works on Linux and Netbsd there is a symlink _mymodule.so --> ../.libs/libmymodule.so

but on osx, python’s import mymodule won’t find

_mymodule.dylib --> ../.libs/libmymodule.dylib

I’ve tried adding

export DYLD_LIBRARY_PATH=.:$DYLD_LIBRARY_PATH

to the script env, nogo. Any help appreciated.

update 4/6/10:

Solved with the info from krunk below. But just copying or ln -s’ing the dylib to a .so name didn’t solve it completely. Still wouldn’t load. But telling libtool to link the lib with the -module flag created a .so lib that would load. Python version of the lib works now.

Now if I could just get the perl lib working. I’m building swig perl, python, ruby, and lua libs and this fix only got python and lua working.

    Just use *.so as your module extensions in OS X too. I have a vague memory of not being able to load .dylib’s and it turning out to be an issue with python itself. . . but I can’t find the mailing list post now.

    However, rest assured you’re following standard practice by using *.so’s even on OS X. The only *.dylib’s in the entire framework are the libsvn_swig ones.
