Sorry for the long time in replying...

Do you want to call python code from C++?

Create a Py::Callable object and use its apply() method to call
the python code.

The pysvn project uses pycxx and uses a lot of its features.
Its project page is http://pysvn.tigris.org. It may have examples
that an useful to you.
