title: No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=armv7 armv7s)
body: <p>Running in Xcode is correctly, but when I want to use command line with 
     $ /usr/bin/xcodebuild -scheme projectA -workspace projectA.xcworkspace -configuration Debug clean build </p>
  
  <p>And come up with the following.</p>
  
  <pre><code>=== BUILD NATIVE TARGET projectA OF PROJECT projectA WITH CONFIGURATION Debug ===
  Check dependencies
  No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=armv7 armv7s).
  </code></pre>
  
  <p>In Build Settings are:</p>
  
  <ul>
  <li>Architectures: Starndard (armv7, armv7s)</li>
  <li>Base SDK: Latest iOS (iOS 6.0)</li>
  <li>Build Active Architecture Only: Debug Yes, Release No</li>
  <li>Valid Architectures: armv7 armv7s</li>
  </ul>
  
  <p>After I change <code>Build Active Architecture Only = No</code>, then the build was BUILD SUCCEEDED.</p>
  
  <p>What is the suggestion setting for this situation, to build success under commend line mode? Thanks.</p>
