I recieve the following error message when configuring a project on macOS with Xcode 14.3.

Thanks for the report! I think this might be related to #3039. Can you try running clang -v and clang --version on the command line outside of VS Code and let me know what the output is?

[H-G-Hristov]

This is the output:

% clang -v Apple clang version 14.0.3 (clang-1403.0.22.14.1) Target: arm64-apple-darwin22.4.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

% clang --version Apple clang version 14.0.3 (clang-1403.0.22.14.1) Target: arm64-apple-darwin22.4.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I believe the error started occurring after Xcode 14.3 but I cannot confirm that. It's a very basic cmake test project. I have more complicated projects that do not exhibit this behaviour. Maybe they just set the correct compiler via CMakePresets.

Thanks. Given that a version number is reported for both the -v and --version flags, this is no longer related to #3039. We'll try to reproduce the issue and get back to you if we have any additional questions.
