My source build was working, prior to my vacation (around 5 weeks ago). I am on an M1 mac

I notice that that the mac build instructions have changed. I have brew installed llvm. I run the setup command that is in the latest docs.

export CMAKE_PREFIX_PATH=${CONDA_PREFIX:-"$(dirname $(which conda))/../"}

MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python build --cmake-only
ccmake build

I get an output :slight_smile: ARMIE_COMMAND                    ARMIE_COMMAND-NOTFOUND

I think the issue os that cmakecache.txt contains line
This file is generated from the cmake command - so I cannot just comment this line out.
I do not have an armclang++ to run here - I am running clang++.

any thoughts?

I force reinstalled conda and this went away.
