I am running into problems with FLUKA on a MacBook Pro with M1 Max chip running Sequoia 15.0.1.

Here are my steps:

  * Via brew, I installed GNU Fortran (Homebrew GCC 14.2.0_1) 14.2.0. (confirmation via gfortran --version)
  * I downloaded fluka2024.1-macm123-gfor64bit-14.2-AA.tar.gz, which should work for Mac Silicon M1 chips and gfortran 14.2.
  * I also downloaded fluka2024.1-data.tar.gz.
  * FLUPRO is pointing to the directory where I untarred the fluka2024... tar.gz file.
  * FLUFOR is pointing to the above-mentioned gfortran.
  * The command "make" worked and created flukahp.
  * However, when I ran, I got the following crash:
================================ Running FLUKA for cycle # 1 =============================================
/Users/bauerj/fluka/fluka2024.1-macm123-gfor64bit-14.2-AA/flutil/rfluka: line 381: 45460 Illegal instruction: 4 ${EXE} 2> $LOGF > $LOGF

Any suggestion how to proceed? Thanks!
