Restoring PPC, SDK 10.4/10.5 and GCC 4.0 Support to Xcode4

This still works with Xcode 4.3.2 from the AppStore - the version where everything is self-contained in an App bundle. As in the original hint, install Xcode 3.2.6 first* and then download Xcode 4 from the AppStore.
Then do the following symlink magic:
  • cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
  • ln -s /Developer/Xcode3.2.6/SDKs/MacOSX10.5.sdk .
  • cd /Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2/bin/
  • ln -s /Developer/Xcode3.2.5/usr/llvm-gcc-4.2/bin/powerpc-apple-darwin10-llvm-g* .
  • mv powerpc-apple-darwin10-llvm-gcc-4.2 powerpc-apple-darwin11-llvm-gcc-4.2
  • mv powerpc-apple-darwin10-llvm-g++-4.2 powerpc-apple-darwin11-llvm-g++-4.2

The last two lines rename darwin10 to darwin11 in the symlink - I'm guessing future versions of OS X will require this to be updated as appropriate.

* To install Xcode 3.2.x on Lion, mount the Xcode disk image, open Terminal, enter the commands (using bash, or the equivalent commands if you've changed your default shell):
  • export COMMAND_LINE_INSTALL=1
  • open "/Volumes/Xcode and iOS SDK/Xcode and iOS SDK.mpkg"
You'll also need to set the clock back to a date prior to 31st March 2012 otherwise security certificates will fail validation during installation. You can safely change the date back again after installation obviously!
