title: Restkit: expected ';' after top level declarator
body: <p>I am new to iOS development so apologies if my question is uninformed. I am trying to run my simple app in the simulator but the build is failing.  Specifically, it is choking on the first line of the following:</p>
  
  <pre><code>FILEMD5HASH_EXTERN CFStringRef FileMD5HashCreateWithPath(CFStringRef filePath; 
                                                       size_t chunkSizeForReadingData);
  </code></pre>
  
  <p>The error tag is as follows :</p>
  
  <pre><code>Expected ';' after top level declarator
  Unknown type name 'FILEMD5HASH_EXT...'
  </code></pre>
  
  <p>Is there an obvious (or not obvious) fix for this...? </p>
