I'm a big fan of Boost.Python, and I'd strongly recommend it over SWIG
if you have anything remotely complex in your C++ (though I don't know
much about Cython, and it may well be better in this case).
That said, it's also very true that Boost.Python hasn't seen much in the
way of active development aside from bug and compatibility fixes for
years. So the Numeric interface in the Boost.Python main library is
indeed way out of date, and not very useful.
But there is a very nice extension library in the Boost Sandbox:
or (equivalently) on GitHub:
Disclosure: I'm the main author. And while we've put a lot of effort
into making this work well and I use it quite a bit myself, it's not
nearly as battle-tested (especially on non-Unix platforms) as many of
