I have an OOT module that uses Protobuf. Normally I link this against libprotobuf.so, however when I do this and attempt to import my module in python, I get errors about undefined symbols. If I link against libptorobuf.a instead I don't have this problem (although I have yet to check that the code will actually work).
I haven't made a toy case for this yet that I can post. Before I did I figured I'd ask if this was something simple and known.
