title: Import, use and compile a single c++ header file in an ios objective-c project
body: <p>I'm sure the answer is simple but I am facing the following problem ...</p>
  
  <p>I want to use this c++ header file <a href="http://www.f2dd.info/Developer/Examples/CoreAudio/PublicUtility/CAAudioUnitOutputCapturer.h" rel="nofollow">CAAudioUnitOutputCapturer.h</a> (there is only a .h file) inside an ios objective-c xcode project.</p>
  
  <p>Could someone tell me how to eliminate compilation errors and give me an example of how to use in Objective-C context?</p>
  
  <p><strong>Edit</strong>, i got this error :</p>
  
  <pre><code>CAAudioUnitOutputCapturer.h:64: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'CAAudioUnitOutputCapturer'
  </code></pre>
