xcode-select cannot locate clang, even after installing command line tools

Question

When I try to run the clang command, I get the following error:

xcode-select: Failed to locate 'clang', requesting installation of command line developer tools.

And then I receive this pop-up:

However, no matter how many times I click "Install" - going through a 15-minute install process - I continue to get the same error.

I have also tried running xcode-select --install however that gives the following error:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

I have also tried manually installing from here.

I'm on an M1 mac running macOS Monterey Version 12.5.

It also yields a core dump:

How can I install clang?

This cured the situation for me! Started happening since updating to Monterey 12.6 — taiyodayo, Oct 03 '22 at 04:34

Please ensure Xcode packages are up-to-date — try running xcodebuild -runFirstLaunch.

This worked for me.

FWIW, this solved my problem for git (for Android Studio) git integration – Tash Pemhiwa Oct 14 '22 at 16:19

Thank you so much. Then, what means this command? – JinYeong Kim Oct 20 '22 at 05:35

For those who are wondering where the command came from, actually it is mentioned in the error message. Check and see line #10 of the original poster's "core dump" message. – untidyhair Oct 22 '22 at 23:17

I had the same problem and updated Xcode, relinked paths etc, which didn't help.

What worked was opening Xcode after the update and accepting the prompt to load essential development tools (for macOS and iOS).

A bit hidden in the error message is also the CLI solution: "Please ensure Xcode packages are up-to-date — try running 'xcodebuild -runFirstLaunch'."

After installing XCode 14.1 on MacOS Ventura 13.0.1, my clang didn't work with an error very similar to this, and repeatedly tried to install the XCode command line tools. It turns out that xcode-select was pointing to the command line tools that are part of the full XCode package, and failing to find clang in there. clang is included in the command line tools package, but not in some versions of the full XCode package.

What I did to fix it was:

sudo xcode-select -switch /Library/Developer/CommandLineTools

This switches the location that clang and other tools are run from. If you want to switch back to running them from the XCode package, you can use:

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

This solved it for me at first, but I had to use `xcrul altool` and the error occurred again. Searching better, I remembered that I had changed the SDKROOT value in my `.zshrc` (it could also be in `.bash`). Before: `export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.3.sdk` After: `export SDKROOT=//MacOSX13.1.sdk` To confirm the version, just follow the same path. I also needed to run it back from the XCode package `sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer` — João Felipe Santana, Mar 25 '23 at 02:04

You can also open Xcode, select the default runtime tools (MacOS and iOS in my case), then clang should run as normal.

I believe this is the same as doing @LanderTome's answer, but not able to verify.
