Re: [boost] Newbie question: how to compile python modules?

It looks like you may be missing the boost python library itself. If you are
using the latest released boost version, that's the one called libpycpp.a
(in the next release, it will be libboost_python.a).

Also, I'm nearly certain that the documentation is still out-of-date. You
might try building one of the examples in examples directory.

Ralf, have you any pointers for this gentleman?
