xcrun: Error: failed to exec real xcrun. (No such file or directory)

Question

I\'ve upgraded OSX Lion to Mountain Lion and reinstalled the Command Line Tools (as the upgrade deleted them). From then xcrun does not work anymore. The xcode-select is set

Answer 1

I had the same problem. Originally I was doing the following for my xcode-switch:

$ sudo xcode-select -switch /Applications/Xcode.app/

However what was really needed was:

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/

This fixed the problem for me. Not sure if sudo is needed.
