How to install numpy 1.8 dev on Windows?

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.

I've solved it.

First make sure you have Visual Studio 2008 installed and possibly MinGW. Then you need to install http://software.intel.com/en-us/intel-mkl 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.
