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?

Bump. I've tried uninstalling the command line tools with the script provided in this article: cocoanetics.com/2012/07/… and I'm still having the same problems. I reinstalled the command line tools using the separate download. Still have the same problem. – Smallish

Answer 1

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

OSX 10.8 xcrun (No such file or directory)

Just made a clean reinstall of my Mac. Mountain Lion, command-line tools, homebrew, rvm. And I came across this issue. The xcrun hack, though quite ugly, works well. Thanks a lot for pointing this out, I wouldn't have found the other discussion otherwise. – Yellowgreen

Answer 2

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.

Worked for me, but I had to replace Xcode.app with Xcode_4.4.1.app because I renamed my Xcode.app file. – Hoxie

Unfortunately, this won't work for OP's situation (mine too) where the standalone Command Line Tools are installed in /usr/bin. – Fertilizer

After struggling for days with this issue I found in this post my answer. Thanks a lot!. It should be marked as accepted. – Ceratoid

This fixed an issue I was having with the TestFlight desktop app failing to build the IPA to upload, thanks! – Katzman

If you are using Xcode5 preleases, you'll have to explcitly point to them, sudo xcode-select -switch /Applications/Xcode5-DP5.app/Contents/Developer/ – Contempt
