I think I can help you with design of code generator. I created code
generator for
Boost.Python library and I am very pleased with it's design. It is
very powerful and simple.
So if you want, we can discuss it.

It seems to me that the problem is that you did not build Boost.Python
right( == using bjam ). Or may be you forgot to add it to link line?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
See one of the recent threads. Py_Finalize could not be used with Boost.Python
library.
