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?
Please ensure Xcode packages are up-to-date — try running xcodebuild -runFirstLaunch.
This worked for me.
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'."
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.
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
I'm using Macbook pro m1, after data migration or update to monterey（not sure which cause this）, golang seems can't debug or go list -compiled. I tried to reinstall/update golang and the result is same
go version: 1.17.3 darwin/arm64
Error msg when I start debug
Build Error: go build -o /var/folders/x8/s3w_s9rj0qj74hs68wvqs1740000gp/T/__debug_bin4251008076 -gcflags all=-N -l .

Error msg when go list -compiled
# runtime/cgo

confcenter
what can i do, any idea?
You need to reinstall the CommandLineTools. xcode-select says everything is up to date, but this information seems to be false.
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
I'm having problems getting a cmake project to compile with xcode on macOS Mojave. Here's the error message associated with the build problem.
-- [polly] Used toolchain: Xcode (OS X default) / clang / LLVM Standard C++ Library (libc++) / c++11 support
xcodebuild: error: SDK "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk" cannot be located.
xcrun: error: unable to lookup item 'SDKVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk'
'xcrun --show-sdk-version' failed
Additionally, I've stumbled on the following incoherence.
localhost:~ ram$ xcrun --show-sdk-path
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk
localhost:~ ram$ xcrun --show-sdk-version
xcodebuild: error: SDK "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk" cannot be located.
xcrun: error: unable to lookup item 'SDKVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk'
I've also noticed that xrun is able to find 'MacOSX10.13.sdk', but not in the same path:
localhost:~ ram$ xcrun --sdk macosx10.13 --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk
Does anyone know what might be the problem and, more importantly, how to fix this?
When I type pod init, i got this message:
sh: line 1: 4169 Bus error: 10 /usr/bin/xcrun clang 2>&1
I have also this error message when I type : brew doctor (sh: line 1: 4389 Bus error: 10 /usr/bin/xcrun clang 2>&1)
And when I type :pod repo update --verbose i got the same :
sh: line 1: 4405 Bus error: 10 /usr/bin/xcrun clang 2>&1
I think it comes from clang, because when I just type clang i got :
Bus error: 10
Anyone has a idea of what it is wrong ?
Thanks !
PS: I tried to remove all /Users/User_Name/Library/Developer/Xcode/DerivedData/. folders and it does nothing to solve my problem
All my apps are not compiling anymore, and then 2 Apple Mach-O errors appear.
this is what Xcode shows:
clang: error: unable to execute command: posix_spawn failed: Exec format error
clang: error: linker command failed due to signal (use -v to see invocation)
To solve it, just download the packs that are on:
Xcode -> Preferences -> Downloads
