title: Installing NumPy and SciPy on 64-bit Windows (with Pip)
body: <p>I found out that it's impossible to install NumPy/SciPy via installers on Windows 64-bit, that's only possible on 32-bit. Because I need more memory than a 32-bit installation gives me, I need the 64-bit version of everything.</p>
  
  <p>I tried to install everything via <code>Pip</code> and most things worked. But when I came to SciPy, it complained about missing a Fortran compiler. So I installed Fortran via MinGW/MSYS. But you can't install SciPy right away after that, you need to reinstall NumPy. So I tried that, but now it doesn't work anymore via <code>Pip</code> nor via <code>easy_install</code>. Both give these errors:</p>
  
  <ul>
  <li>There are a lot of errors about <code>LNK2019</code> and <code>LNK1120</code>,.</li>
  <li>I get a lot of errors in the range of <code>C</code>: <code>C2065,</code>C2054<code>,</code>C2085<code>,</code>C2143`, etc. They belong together I believe.</li>
  <li>There is no Fortran linker found, but I have no idea how to install that, can't find anything on it.</li>
  <li>And many more errors which are already out of the visible part of my cmd-windows...</li>
  <li><p>The fatal error is about <code>LNK1120</code>:</p>

  </blockquote></li>
  </ul>
  
  <p>What is the correct way to install the 64-bit versions NumPy and SciPy on a 64-bit Windows machine? Did I miss anything? Do I need to specify something somewhere? There is no information for Windows on these problems that I can find, only for Linux or Mac OS X, but they don't help me as I can't use their commands.</p>
