How to install numpy 1.8 dev on Windows?

Question:

I'm trying to install numpy 1.8 dev on Windows. I cannot find any binaries, only 1.7.1. Does anyone know where to download it?

Alternatively, I also tried to build numpy myself. I donwloaded the latest source from Github and ran python setup.py install, but I get an error RuntimeError: Broken toolchain: cannot link a simple C program. Here's some of the output. I have VS 2008 installed with both 32x and 64x compilers as well as MinGW 32x.

Answer1:

I've solved it.

First make sure you have Visual Studio 2008 installed and possibly MinGW. Then you need to install <a href="http://software.intel.com/en-us/intel-mkl" rel="nofollow">http://software.intel.com/en-us/intel-mkl</a> then need to create a site.cfg file under your numpy/distutils/ in your source. add this to it

[mkl] include_dirs = C:\Program Files (x86)\Intel\Composer XE 2013\mkl\include library_dirs = C:\Program Files (x86)\Intel\Composer XE 2013\mkl\lib\ia32 mkl_libs = mkl_ia32, mkl_c_dll, libguide40 lapack_libs = mkl_lapack

Then go to your python installation to C:\Python27\Lib\distutils\distutils.cfg Make sure it's empty! and has no such things as

[build] compiler=mingw32

This will throw off your installer. You can add C:\MinGW\bin to the Path, not sure if this is needed though. Finally, go back to your numpy source directory and run python setup.py install. Should compile without errors.
