Re: [C++-sig] Boost Python Question - Multiple Classes and Modules not appearing as attribute

Hi,

Thanks for the response.  However, this example doesn’t work for me either if I set the shared object file to zoo.so.  It doesn’t find the animal attribute:

http://pyengr.readthedocs.io/en/latest/inter/bpy

Can you explain why?

Thanks.

Jon
