Visual Studio Code Debug C++ on Mac

 

When you try to debug C++ in Visual Studio Code on Mac, you might have the following error:

Errors exist after running preLaunchTask 'C/C++: clang++ build active file'.

It might because you don't use the correct version of the compiler, use the following launch.json and tasks.json files instead:

 

tasks.json:
