title: How to configure environment to build python-embedded c code with LLVM Clang
body: <p>I'm trying to compile a program written in c that has python embedded in it.</p>
  
  <p>I ran <code>python3.3-config -cflags</code> to get the cflags I've used in this command.</p>

  </code></pre>
  
  <p>It seems as though clang is having trouble locating headers maybe? <code>&lt;Python.h&gt;</code> is included in the source I'm not sure what I'm doing wrong :/ </p>
  
  <p>Ive spent about 3 hours looking through the python documentation <a href="http://docs.python.org/3.3/c-api/index.html" rel="nofollow">http://docs.python.org/3.3/c-api/index.html</a> and googling around, but I cant seem to find any information that helps me.</p>
