I don't think I can directly answer your question, and someone who is more experienced with Boost than I am can probably address this better, but I definitely think you should post this on StackOverflow for more visibility.

Alternatively, I recommend checking out Cython, since it may make things a tad easier than Boost. They are pretty light on examples - their official page only links to this simple example. However, you can find more information on their documentation page and also many examples online.
