Embedding Pythonwin - Python reports Fatal Error

[rfisher at iee.org.uk]

I'm trying to embed Python in an application to add scripting to it.
To add an interactive window I'd like to use Pythonwin.

I have been following the documentation at
http://www.python.org/windows/pythonwin/EmbeddingWin32ui.html

Everything compiles nicely, but when I call
Win32uiHostGlue::DynamicApplicationInit() the application crashes with
the message "Fatal Python error: Can not setup interpreter state, as
current state is invalid" in the trace window.

Further investigation reveals that this error occurs on the line in
Win32uiHostGlue.h that reads:

rc = (*pfnInit)(this, (char *)cmd, additionalPaths);

I've looked at what this does but there are no clues as to what the
problem might be.  The error seems to be generated by Python rather
than Pythonwin, so perhaps I am missing something during
initialisation.  Anyone have any ideas?

Are there any examples of Pythonwin embedded in an application floating
around?  Failing that, can anyone suggest a good way of implementing an
interactive Python window under VC++/MFC ?  I think that Python is an
excellent way to add scripting to an application, and an interactive
window would make it so much more fun for the user!

thanks,
Rob.
