undefined symbols when embedding python

Hey Martin,

Yes, the extension module is in a shared library.

Most of this is all pretty new to me, so for whatever reason, the approach of
extension library + separate embedded executable seemed more natural to me.

I'll give both ways a shot (extended module + embedded, and embedded with the
wrapper directly in it).  Now that I think of it, I cannot think of any reason
not to have the wrapped classes directly in the embedded app.

Thanks for the tips!
