title: Installing OpenMP on Mac OS X 10.11
body: <p>How can I get OpenMP to run on Mac OSX 10.11, so that I can execute scripts <strong>via terminal</strong>?</p>
  
  <p>I have installed OpenMP: <code>brew install clang-omp</code>.</p>
  
  <p>When I run, for example: <code>gcc -fopenmp -o Parallel.b Parallel.c</code> the following expression returns: <code>fatal error: 'omp.h' file not found</code></p>
  
  <p>I have also tried: <code>brew install gcc --without-multilib</code> but unfortunately this eventually returned the following (after first installing some dependencies): </p>
  
  <pre><code>The requested URL returned error: 404 Not Found
  Error: Failed to download resource "mpfr--patch"
  </code></pre>
  
  <p><strong>Any recommended work arounds?</strong></p>
