This list seems to have fallen out of date: http://boost.org/libs/python/doc/v2/platforms.html I am working on a GUI widget which uses embedded python. Under windows, the GUI system supports MSVC 6.0, 7.0, and 7.1. If I use Boost.Python will this restrict my widget to being MSVC 7.1 only? I have heard that the current Boost.Python only really works under 7.1, but I don't see anything about it in the documentation. Thanks. Clay
