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 am receiving the error "5 duplicate symbols for architecture x86_64" when attempting to launch my React Native project in Xcode. I am using a MacBook Pro, chip Apple M1 and macOS Monterey v 12.2.1. Has anyone had this issue before and managed to resolve it? Can you please help? I have tried other fixes but these failed to work. Below is my podFile:
Error log:

ld: 5 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I receive the below error if I uninstall rn-fetch-blob, run pod install and then run the app in Xcode:
I need the RNFetchBlob package since I am using it in my code or is there something else I can use as the equivalent? Is react-native-blob-util the equivalent? Can someone help please?
Go to xcode select pods under Targets click on react-native-fetch-blob and
select no common block from yes to no
repeat this process for react-native-blob-utils

I've downloaded the older version of Xcode 9.4 that supposed to be compatible with Matlab R2017.b and set the path to it:

/Applications/Xcode.9.4.1.app/Contents/Developer
any suggestions would be grand!
It is a test-drive example "https://flutter.io/get-started/test-drive/#terminal"
I have got the following error, please comment how to resolve this issue.

Error launching application on iPhone 7 Plus.
I have resolved the issue as the following:
If you look at the question carefully, it triggered an outdated version of clang 3.5, I uninstalled an outdated version and installed a new one.
remove clang-omp from os x
$ brew uninstall clang-omp
After uninstall clang-omp, flutter installer required to update to the latest version. Actually, I did the update before but I did it again.
$ flutter upgrade
I try to run flutter again but it cannot be compiled. It was missing clang-omp
$ flutter run

Because it required an updated version of clang during compilation. I installed llvm
$ brew install llvm
and update the PATH accordingly.
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile
Compile the application again, it was compiled successfully.

I rarely build anything from source, so I really have no idea what's going on here, but have done good few hours of googling and still can't solve it...
