title: How to run project with Gdata library
body: <p>I use gdata framework and I want to create youtube app with GDataYoutube library. I make project with cross-references project Gdata, but now I have a problem with option in xcode 4 -> product -> archive. When I build my app I get this error: 'The service placeholder compiler flag should be replaced by actual service specifications'</p>
  
  <pre><code>#if !DEBUG
    #if GDATA_INCLUDE_nameServiceHere_SERVICE &amp;&amp; !GDATA_SUPPRESS_INCLUDE_WARNING
      #error The service placeholder compiler flag should be replaced by actual service specifications
    #endif
  #endif
  </code></pre>
  
  <p>Thanks for any help!</p>
