How to remove cling?

Question

After run clang --version on my MAC OS 10.15 Catalina, I got this result:

clang version 5.0.0 (http://root.cern.ch/git/clang.git 7fd3024be56d751958d68ea3abeca4ab2f89dd91) (http://root.cern.ch/git/llvm.git e0b472e46eb5861570497c2b9efabf96f2d4a485)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Users/user/cling/bin

When I use cmake, it keeps using the clang installed by cling. Now I get errors when compile c++ code with header file cmath.h included. How to uninstall cling and use Apple clang?

Answer 1

Assuming the install was self-contained as shown, you can get rid of it with:

rm -r  /Users/user/cling

Then you'll want to remove whatever got into PATH to point you to cling.
