title: Redirecting debug output from XCode 4 console to a log file
body: <p>I'm working on automated testing for iPhone, and I need to redirect output from gdb to a log file. Some searching online turned up the following two lines to run at the command line before beginning debugging:</p>
  
  <pre><code>defaults write com.apple.Xcode PBXGDBDebuggerLogToFile YES
  defaults write com.apple.Xcode PBXGDBDebuggerLogFileName &lt;filepath&gt;
  </code></pre>
  
  <p>...but they don't seem to work for me. I've had problems in the past with functionality from previous versions of Xcode disappearing in newer versions (I'm using XCode 4.0.2).  Is that the case here, or is it more likely that I'm just doing something wrong?</p>
  
  <p>Is there another way to tell XCode to send output to a log file? Note that I need to be able to do this from the command line or AppleScript; I can't add anything to the code of the program being run.</p>
