Use OpenMP with Windows SDK

I am aware that VC2010 Express Edition does not include OpenMP support and therefore would report omp.h file missing. Therefore, I have installed Windows SDK v7.1 64-bit version in Windows. However, even I ran:

set DISTUTIL_USE_SDK=1
setenv /x64 /release

And then try to compile the code, it would still report cannot find omp.h. Could anyone give me a hint on how to solve this?

Are you building from the command line or from VS? If you're building from VS, you'll need to add the Windows SDK headers & libs to the include paths (Tools/Options/Projects & Solutions/VC++ Directories). – Eric Brown
@EricBrown From the command line. I am actually using Cython in case you are familiar with it... It is essentially calling cl from the command line. – Yuxiang Wang
@EricBrown And also, I searched the SDK folder and did not find omp.h... OpenMP support seems to be not shipped with it, is that true? – Yuxiang Wang
The express edition of MSVC2012 and MSVC2013 both support OpenMP (It's what I use). I have not found any official documentation on this but if you download either of them you will discover this. – Z boson
@Zboson I thought that Python 3.3 will need MSC v1600, which is the version that compiled the CPython itself. I do have MSVC2012 installed but I do not know how to set Python to work with MSVC that is not VC2010 though... – Yuxiang Wang

Did some checking, and it appears that OpenMP is not part of the Windows SDK, and is only shipped with Visual C++ 2010 Professional or Ultimate editions.
