Find out the path location to Command Line Tools for Xcode

Question

I didn't want to install the whole Xcode, so I just downloaded the command line tools for Xcode. I am trying to install ruby 1.9.3 via rvm. However, rvm complains that no xcode is selected:

xcode-select: Error: No Xcode is selected. Use xcode-select -switch , or see the xcode-select manpage (man xcode-select) for further information.

I read the xcode-select manpage and I know how to set the path to the Xcode Command Line Tools, but I don't know where they are installed. How do I find this out?

I am using OS X Mountain Lion.

Answer 1

This worked for me: sudo xcode-select --reset

Answer 2

The entries in /usr/bin are just a front for whatever you choose with xcode-select:

$> /usr/bin/clang --version
Apple LLVM version 8.0.0 (clang-800.0.38)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

The standalone command line tools are installed in /Library/Developer/CommandLineTools:

$> sudo xcode-select -s /Library/Developer/CommandLineTools
$> /usr/bin/clang --version
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
