As with a few others here, my French is enough to understand just not good enough to reply ;-)

You should definitely check out Boost.Python. It makes embedding relatively trivial obviating the need to create shared libraries for your Python wrappers (which really tend to get in the way when you're embedding only). IMHO, every other alternative is either cumbersome or unclear when it comes to object ownership issues <.5 wink>.

The latest documentation is available at http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/python/doc/index.html (the tutorial should get you up to speed quickly).

A complete embedding example (calling a Python class derived from a c++ class) is at: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/python/test/embedding.cpp (look ma' no reference counting! ;-)

To call Python objects, check: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/python/doc/v2/callbacks.html
