• Titanium Developer is running a python script in the background to determine which SDK versions you have installed. In order for our python script to detect the presence of Xcode, you must have the xcodebuild command on your system path. Typcially, a link is automatically created at /usr/bin/xcodebuild by the Xcode installer. You can check to see what Titanium is seeing by running python ~/Library/Application\ Support/Titanium/mobilesdk/osx/(SDK version)/iphone/prereq.py project.

  If this fails (and xcodebuild is not on your path), you will need to manually add /Developer/usr/bin to your path, or reinstall Xcode to have it properly configure your system path for you (the latter option might be better if possible, since I'm not 100% sure what else the Xcode installer does).

• I executed the script and got the success response back . So I am not sure about the problem.

  Purushothaman-Loganathans-Mac-mini:iphone purush$ ./prereq.py project
  [DEBUG] executing command: xcodebuild -showsdks
  {"success":true, "sdks":["3.2","4.0"],"ipad":true}

• @Kevin: Slight error in your response which may confuse people:

  Please remove the "~" or tilde in this path which means relative to the user's root.
  ~/Library/Application\ Support/Titanium/…

  You really want the absolute path I think:

  /Library/Application\ Support/Titanium/…

• I am having the same problem. Running Snow Leopard and iTunes 10, just downloaded the latest iOS SDK 4.1 and Titanium 1.2.1, have tried the default 1.4.0 SDK and even the more recent 1.4.2, tried all the tricks from all the articles I could find on this subject (replacing the prereq.py script file, adding /Developer/usr/bin so xcodebuild could be found, updated all my certificates, deleting contents of my build directory, etc.), nothing seems to help. If I create a new project, it gives me the error the SDK can't be found, if I try to compile KitchenSink, it hangs on One moment, building.

  prereq.py seems to return a successful result:

  $ ./prereq.py 'KitchenSink'
  {"wwdr":true,"iphone_dist_name":["ABC, Inc."],"sdks":["4.1","3.2"],"iphone_dev_name":["Eric Alderman (JF9FHC69VG)"],"iphone_dist_message":null,"wwdr_message":null,"itunes_message":null,"itunes":true,"iphone_dev_message":null,"iphone_dev":true,"iphone_dist":true,"ipad":true,"itunes_version":"10.0"}

  This is pretty darn frustrating.

• Got it to work by adding the Xcode unix tool directories to the $PATH. Just in case, here is a script that does it for you (instructions below)

  #!/bin/sh
  # based on git-osx-installer
  append_path () {
    input="$1"
    value="$2"
    if ! echo $input | /usr/bin/egrep -q "(^|:)$value($|:)" ; then
       if [ "$3" = "after" ] ; then
          echo $input:$value
       else
          echo $value:$input
       fi
    else
      echo $input
    fi
  }
  
  append_plist_var() {
    name="$1"
    append_value="$2"
    default_value="$3"
    current_value="`defaults read $HOME/.MacOSX/environment ${name}`"
    [ ! "$current_value" ] && current_value="$default_value"
    new_value="`append_path "$current_value" "$append_value" after`"
    defaults write $HOME/.MacOSX/environment "$name" "$new_value"
    if [ "$current_value" == "$new_value" ]; then
      echo "No change to $name in ~/.MacOSX/environment.plist"
    else
      echo "Variable $name in ~/.MacOSX/environment.plist changed from '$current_value' to '$new_value'"
    fi
  }
  
  append_plist_var PATH "/Developer/usr/bin" "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin"
  append_plist_var PATH "/Developer/usr/sbin" "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin"
  
  pushd "$HOME"
  
  popd
  

  1. Copy the code to a plaintext document.
  2. Save it as "add-xcode-path.sh" (for example).
  3. Open up Terminal and execute the script file: sh add-xcode-path.sh
  4. Log out from OSX, log in again and restart Titanium.

  Note: YOU MUST LOG OUT FROM OSX AND LOG IN AGAIN FOR THE PATH CHANGE TO TAKE EFFECT.

  It blows that Titanium Developer doesn't simply allow you to select an Xcode directory manually (like "/Developer").
