We added an extra sanity check that was intended to guard against someone using a Python built with MSVC 6, say, and a DLL built with MSVC 7. The sanity check is that distutils finds out what compiler was used to build Python, and won't compile extensions with anything else. (I think I added this code.)
Er... I can build extensions quite happily with the mingw32 compiler, against a stock Python 2.3 for Windows. [...] Don't "fix" this, please! It would be a real problem if users couldn't build C extensions with free tools, without having to build the whole Python interpreter as well.
Looks like (from other postings) that the check is in MSVCCompiler, and so doesn't apply to mingw builds (the original problem seems to have been an issue with the particular setup.py). So it looks like everything's OK for now, otherwise. As I said, once a MSVC7 compiled Python is available for me to test with, I'll look at getting mingw builds working appropriately. I guess I'll be able to steal the version test from msvccompiler.py to help me set the appropriate compiler flags... Cheers, Paul.
