Is it possible to install and switch between multiple version of Command Line Tools in Mac OS X? I was wondering if it's possible use xcode-select
but the Command Line Tools installer doesn't have an option to choose the installation destination. I tried to create multiple installations by manually renaming Library/Developer/CommandLineTools
and then passing it to xcode-select
. The command succeeds but when I try to access gcc I get:
gcc: error: unable to find Xcode installation from active developer path "/Library/Developer/CommandLineTools_9.0.0", use xcode-select to change
It seems this is possible when installing the whole XCode but I have no need for XCode and prefer not to install it. All I need is the command line tools.

I tried to do the same and after some experiments found the next solution. Yes, it is possible but you need to copy/rename the whole /Library/Developer
folder. For example:
1) first, I just show my macOS version:
$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.13.6
BuildVersion: 17G65
2) download and install Command Line Tools for Xcode, e.g. 10b5 version
3) create folders to store different versions of tools:
$ mkdir ~/Project/tools
$ mkdir ~/Projects/tools/Developer10b5
$ mkdir ~/Projects/tools/Developer9.4.1
4) copy the whole Developer folder:
$ cp -R /Library/Developer/ ~/Project/tools/Developer10b5/
5) then, download and install Command Line Tools for Xcode, e.g. 9.4.1 version
6) copy the whole Developer folder:
$ cp -R /Library/Developer/ ~/Project/tools/Developer9.4.1/
7) switch to 9.4.1 version of tools and check the clang version:
$ sudo xcode-select -s ~/Project/tools/Developer9.4.1/
$ clang --version
Apple LLVM version 9.1.0 (clang-902.0.39.2)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Users/<username>/Projects/tools/Developer9.4.1/CommandLineTools/usr/bin
8) switch to 10b5 version of tools and check the clang version:
$ clang --version
Apple LLVM version 10.0.0 (clang-1000.10.40.1)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Users/<username>/Projects/tools/Developer10b5/CommandLineTools/usr/bin

For those who have a problem like as @PaulMasri-Stone, I found that after removing a previously installed Xcode (installing multiple versions of Xcode was not an option on my computer because of space), the method above also gave me the 'invalid developer directory' error.
I overcame this problem by typing sudo xcode-select -r
to reset to the default command-line tools (and reset whatever other underlying state that the system uses to track the SDK location -- and lack of Xcode), followed by sudo xcode-select -s /Library/Developer/CommandLineTools10.13_Xcode9.4.1
. Note that sudo xcode-select -s /Library/Developer
would not work for me, just like the problem that @PaulMasri-Stone had.
Otherwise, you will want to follow the instructions that @Ilirium specified, but you only need to copy/rename the CommandLineTools
directory.
