title: Code Coverage GCov not working with XCode 4.2 and iOS SDK 5
body: <p>I've been trying to get GCov working with Xcode 4.2Build 4D199 on Lion with iOS SDK 5.0 to no avail. Has anyone had any luck with this? I'm using Google Tools For Mac for my unit tests and I've linked in libprofile_rt.dylib and added:</p>
  
  <pre><code>"OTHER_CFLAGS[arch=*]" = (
      "-ftest-coverage",
      "-fprofile-arcs",
      "-falign-loops=16",
  );
  </code></pre>
  
  <p>as indicated on the Coverstory page here <a href="http://code.google.com/p/coverstory/wiki/UsingCoverstory" rel="nofollow">http://code.google.com/p/coverstory/wiki/UsingCoverstory</a>
  But when I find . -name *.gcda" I come up empty. What am I missing?</p>
