[Numpy-discussion] mingw-w64 tutorial ?
Sun Aug 22 07:58:25 CDT 2010
Remember that you will need the Win 7 SDK for .NET 3.5. The version
for .NET 4 links with the wrong CRT. It's 1 GB download so Pick the
correct. Remember that Python distutils needs the environment
variables DISTUTILS_USE_SDK and MSSdk set to use it. The first we must
set manually, the latter comes from running setenv.
VS2008 Express has a 64 bit compiler. It's not available from the
IDE, but we don't need that for Python extensions.
