Hello,
As I’m usinsing an iMAC M (arch64) machine, the  env string is: 
LIBRARY_PATH=/opt/homebrew/Cellar/gcc/11.2.0/lib/gcc/11:/opt/homebrew/Cellar/libgccjit/11.2.0/lib/gcc/11:/opt/homebrew/Cellar/gcc/11.2.0/lib/gcc/11/gcc/aarch64-apple-darwin20/11.1.0

Actually the compiler session succeeded, and I’m running the build from today right now. The module “comp.cc <http://comp.cc/>” came out with 4 warnings, that all.

Med venlig hilsen
Niels
