So I'm having some difficulty getting one of the boost.python tutorial examples working. In particular the class with a string constuctor.

http://www.boost.org/doc/libs/1370/libs/python/doc/tutorial/doc/html/python/exposing.html#python.constructors This exact example crashes for me in Visual Studio with an exception at line 75 in <boost/python/detail/invoke.hpp>. I've read a few other forum posts and I can only assume there was something wrong with my build / config seeing as this seems like a trivial example. I am using the free boost download (http://www.boostpro.com/products/free) for VC9 and Python 2.5. I'm wondering if this is the right version of Python for that build? I couldn't find in the download any indication of what python version it's expecting, or if it evens matters.

Depends on your python binary. IIUC, python and its extensions needs to be built with the same compiler. (I recall getting complaints on that from setuptools.)

I think Python 2.5 (as released on python.org) was built with VC71. Python 2.6 uses VC90, so going there might help.

P.S. I'd wish Python would use something like JNI to avoid this. Would make it much eaiser to distribute and use extension binaries. IIRC there was a PEP for PNI, but that got voted down. :-/
