title: Unresolved References in Sphinx
body: <p>Let's say I have a project, where (somewhere) the following function is documented:</p>
  
  <pre><code>.. exmpl:cfunction:: ExMpl* ExMplSet( int flags, int size, ExStorage* storage )
  </code></pre>
  
  <p>Somewhere else in that project's documentation we have a reference, that looks like this:</p>
  
  <pre><code>:exmpl:cfunc:`ExMplSet`
  </code></pre>
  
  <p>Everything seems legit and there are other examples of this use in documentation, but as the output Sphinx gives a warning:</p>
  
  <pre><code>~/some_folder/some_file:320: WARNING: unresolved reference: u'ExMplSet' - u'cfunc'
  </code></pre>
  
  <p>There is no link as there should be and 100+ warnings (for the whole project) aren't really that good.</p>
  
  <p>These exact examples are of course made-up. What I'm asking for is some kind of a hint, where to look for the answers.</p>
