title: How to install numpy 1.8 dev on Windows?
body: <p>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?</p>
  
  <p>Alternatively, I also tried to build numpy myself. I donwloaded the latest source from Github and ran <code>python setup.py install</code>, but I get an error <code>RuntimeError: Broken toolchain: cannot link a simple C program</code>. Here's some of the output. I have VS 2008 installed with both 32x and 64x compilers as well as MinGW 32x.</p>
