title: Cython compiled C extension: ImportError: dynamic module does not define init function
body: <p>I have just compiled part of my C library as an extension using Cython, as a "proof of concept". I managed to hack the code (const correctnes problems etc aside), to finally get an extension built.</p>
  
  <p>However, when I attempted to import the newly created extension, I got the following error:</p>
  
  <pre><code>ImportError: dynamic module does not define init function 
  </code></pre>
  
  <p>What am I doing wrong and how do I fix this?</p>
  
  <p>I am using Cythn 0.11.2 and Python 2.6.5 on Ubuntu 10.0.4</p>
