compilers are not detected and found

Hello!

Do you have Xcode command line developer tools installed (https://www.jetbrains.com/help/clion/quick-tutorial-on-configuring-clion-on-macos.html#reqtools)? What output do you get if you execute xcode-select --install in Terminal?

Thanks for your answer. I already installed xcode and running xcode-select --install gives xcode-select: note: Command line tools are already installed….

What does your toolchain in CLion look like? Please provide a screenshot of it from Preferences | Build, Execution, Deployment | Toolchains.

Please empty the “C Compiler” and “C++ Compiler” fields. Do you still see the “Test CMake run finished with errors” message after that?

No I don't.

Is it suitable for you? In this case, CLion will use compilers which it auto-detected. Most probably those are from Xcode command line developer tools. You can check that by hovering over the “C Compiler” and “C++ Compiler” fields.

I appended a screenshot but for some reason it is not shown. Thanks for your answer.

I get this error now

 CMake will not be able to correctly generate this project.
 

Ensure the paths to clang and clang++ are in your PATH variable. Set Xcode command line tools with xcode-select --install. Verify by running clang --version. 

David Schuldes, do you still face the issue, or was it resolved?
