Hi @aarondotter,

New user, and I have an installation issue I've hit on both MacOS (15.0.1) and Linux (Ubuntu 24.10) with MESA 24.08.1 and mesa SDK 24.7.1. After running the ./mk we see:

make: *** [iso_eep_color.o] Error 1

The MESA side appears to be installed fine. It might even be somehow related to this bug (going down the f951 error path):

https://gcc.gnu.org/bugzilla/buglist.cgi?quicksearch=gfc_check_init_expr

Any help and/or suggestions would be greatly appreciated!
