This probably means you haven't initialized Python correctly. A good
starting point might be this example:
https://github.com/boostorg/python/blob/develop/example/quickstart/embedding.cpp

(I'm the Boost.Python maintainer. While I'd be happy to help you using
Boost.Python, I think this is mostly orthogonal to your original
question about how to capture output generated by you embedded Python.)
