Dear GCC Team, I'm running Ubuntu 22 on my Mac virtually and my gfortran version is 11.4.0. When I try to install a certain software package, I encounter the following error: gfortran: error: unrecognized argument in option '-mcmodel=medium' gfortran: note: valid arguments to '-mcmodel=' are: large small tiny Is this due to attempting to run gfortran on arm64 architecture? Could you please let me know how I could resolve the issue?
