Opendiff does not start anymore

Question

Today I tried to use opendiff on my MacBook Pro and I got this error.

xcode-select: Error: No Xcode folder is set. Run xcode-select -switch <xcode_folder_path> to set the path to the Xcode folder.
Error: /usr/bin/xcode-select returned unexpected error.

Do you have any idea why it suddenly start happening and how to fix it?

Answer 1

That is because with 4.3 /Developer/ moved to /Applications/Xcode.app/Contents/Developer/

The proper setting for the new path is:

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

Fixed with:

sudo xcode-select -switch /Developer/

I am still unsure why I stopped working though.

Answer 3

sudo xcode-select -switch /Developer/ 

worked for me

-- I use Versions with FileMerge and started seeing the same error code immediately after upgrading to OSX 10.7.3

Did not work for me (xCode 4.3.1), but this worked fine: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/ – Sickening
