title: Getting 0 gcov coverage for a mac app
body: <p>I have done the following but I am still getting 0% gcov coverage for my .app.  Here is what I am doing:</p>
  
  <ol>
  <li>I am using Xcode 3.2.6, GCC 4.2 and am on Mac OSX 10.6.</li>
  <li>I duplicated the Debug config and call it Gcov.  In the Gcov config and the app target I set the following build configuration:
  <ul>
  <li>Check "Generate Test Coverage Files"</li>
  <li>Check "Instrument Program Flow"</li>
  <li>Add "-lgcov" to "Other Linker Flags"</li>
  </ul></li>
  <li>I did a 'Clean All' then I did a 'Build and Run'.</li>
  <li>Once the build successfully built it launched the app.  I did some quick things in the app and exited.</li>
  <li>When I go view the .gcda/.gcno I see that they have been generated and in fact every time I launch the app and do additional things in the app I see the .gcda/.gcno files are indeed updating.  However, using gcov/gcovr to view the .gcda/.gcno I keep getting 0 coverage.</li>
  </ol>
  
  <p>Any ideas as to what I am doing wrong?  Thanks for any help. </p>
