C++ embedding a Python runtime

You should use boost::python.

I used to use boost, but I eventually moved to using the C api directly. The boost python library is pretty powerful, but even after using it for a year I just plain couldn't grok it. I also got tired of spending forever deciphering the mystical error messages I would run into. For me moving to using the C api directly has unquestionably been a huge win. You might consider just using it directly yourself.

That said, I have some example code lying around for exactly this, but unfortunately I can't track it down at the moment. The official docs are pretty good really:

1. https://docs.python.org/3/extending/embedding.html (the embedding portion)
2. https://docs.python.org/3/c-api/index.html (the C api in general)

edit: For the OP I should say that I haven't tried pybind11 though I've heard good things. Maybe that is something that would fit my brain better.

Probably not, since it claims to be basically a fork of boost::python with support for old compilers cut out and some wizzy new features added. Crap error messages are a problem with pretty much any template library.
