AliRoot Installation Fails at Arrow due to LLVM

Hello,

I’m trying to install O2 on Mac M1 Monterey. The installation fails because of the LLVM package error during the arrow installation. I already have LLVM in /opt/homebrew/Cellar/llvm/14.0.6_1 directory, which came after the installation of prerequired packages.

Below is the error message. I also tried to locate the LLVM_DIR as follows but didn’t solve the problem.

export LLVM_DIR=“/opt/homebrew/Cellar/llvm/14.0.6_1/lib/cmake/llvm”

Any help would be appreciated.

Thank you,
Kind regards,
Ayben

Fixed the issue downgrading LLVM version to 13.
