Hi Neil,

CMake is using whatever "python" is, which is Python2 for me so I get the same error.

You can specify the Python exe directly\[0\] by adding this:

\-DPYTHON\_EXECUTABLE=\`which python3\`

That gets you to:

CMake Error at /work/open\_source/llvm-project/llvm/cmake/modules/AddLLVM.cmake:1543 (add\_dependencies):
The dependency target "clang" of target "check-debuginfo" does not exist.

To fix that you can just add "clang" to LLVM\_ENABLE\_PROJECTS.

There is a specific FindPython3 module \[1\] that debuginfo-tests could use but I'm not sure if it's available in the minimum CMake version we require.

Thanks,

David Spickett.
