python/c++ with microsoft visual c++

finally got a 64 bit pyd python extension working, compiled with ms visual c++ and visual studio for epd on windows. figured out that the version string in python (MSC v.1500 64 bit (AMD64)) was for visual c++ 2008 == v9.0, and the express edition only builds 32 bit. so i had to get the sdk (version 7 works with 2008) and make sure the amd64 stuff got installed with it. some notes say to install the service pack before the 64 bit stuff, but i didn't find this necessary. i ran the 'Windows SDK Configuration Tool' from the start menu, since it sounded logical, and ticked the box to link the sdk with VC 2008. not sure if that was necessary or not. one change i had to kludge manually was changing the references in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat under the amd64 label. originally they were pointing to "%~dp0bin\amd64\vcvarsamd64.bat"; they need to be "%~dp0bin\vcvars64.bat". at that point, running vcvarsall.bat amd64 should work and a simple use of weave passes: import scipy.weave as w c = w.inline(r'printf("hi.");',verbose=2) now that the compiler, etc., are set up i can use swig and distutils to build bigger extensions (like in the swig docs), and it Just Works!
