Getting the Developer Tools

Developer Tools on OS X 10.7 (Lion)

Fixing opendiff / FileMerge

How can I resolve “Error: No developer directory found at /Developer”?

$ opendiff path/to/file1 path/to/file2
Error: No developer directory found at /Developer. Run /usr/bin/xcode-select to update the developer directory path.

$ xcode-select -print-path
/Developer

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

$ xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
