I\'ve updated XCode to 4.5 (with iOS 6) and installed latest command line tools. Before that i always had the latest Clang version in
/Applications/XCode.ap
If you installed the "command line tools for Xcode" you would have clang in a nice, intuitive location like "/usr/bin
".
To get at them, you can go in via Xcode's preferences like this:
or you can click the "Looking for additional developer tools" link at http://developer.apple.com/xcode, where there's a disk image and an installer you can download.
Both of these options install the exact same components.
