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 to /usr/bin, the binaries are in that directory too, but if I run xcrun with an argument (ex. xcrun gcc) it displays this:

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

I've tried setting the path again with xcode-select and reinstalled the CLT. Nothing helped.

Any suggestions how to fix this?

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.

Answer 2

The only fix is hack apparently. I tried the script mentioned and it worked
