Hi,

I am trying to build tot python from https://github.com/python/cpython using
clang tot from: https://github.com/llvm/llvm-project

I am seeing the following error:

How I built clang:
Attached script (get_llvm_os_all.sh) that i used to build clang for different
versions
I am using XCode 12.4 to build clang from source

How I built python:
Attached script (get_python.sh). I build openssl from source, if you already
have it, remove configure flag for openssl
