Hi, Im running Gentoo over here and I installed boost from gentoo's portage tree. I then tried to compile a program that included boost/python.hpp. It completely failed: /usr/include/boost/python/detail/wrap_python.hpp:41:24: patchlevel.h: No such file or directory /usr/include/boost/python/detail/wrap_python.hpp:121:21: Python.h: No such file or directory Looks like I don't have some local variables set to tell things im trying to build where to find these files. Im compiling this absurdly simple program (pretty much just an #include <boost/python.hpp> and a main that returns 0) using a Makefile. Do I need to export some paths? If so, which vars? Do I need to add something to my g++ line? I've never used python's interpreter in c++ and so im not sure what I need to add to my Makefile. Sorry if im not being clear...its kind of late. thanks, Noah
