The current Arm64 port (aarch64 on macOS) only supports the “small” mcmodel “tiny” is not supported by macOS and we have not yet implemented “large”. Despite it’s name “small” should suffice as an approximate equivalent for the x86_64 “medium” (at least on macOS). So, either you need to change the flag depending on the architecture, or omit it (on macOS currently GCC only supports the default mcmodel). We plan to support the “large” model at some stage on Arm64 (but unlikely for GCC 14) HTH, Iain

gfortran: error: unrecognized argument in option '-mcmodel=medium'
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?
