Hi. I'm using Xcode 2.2.1 on a 12" Powerbook running OSX 10.4. I am trying to create a new cocoa project, and everything I build fails with the same error: Code: warning -L: directory name (/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/gcc/darwin/3.1) does not exist unknown flag: -syslibroot A google search for the error turns up nothing. I can see a /Developer/SDKs/Mac10.3.9.sdk/usr/lib/gcc/darwin/3.1 directory but apparently Xcode can not. I also tried downloading the Xcode Legacy Tools from http://developer.apple.com but that doesn't seem to have fixed it either. Any suggestions?
