• Installing gfortran in mac osx Big Sur

    From Pfesesani van Zyl@21:1/5 to Ev. Drikos on Fri Jul 30 06:46:15 2021
    Good day all,

    I'm a newbie also trying to install gfortran on MacOS BigSur with M1 chip. However, I'm
    coming across a lot of "This release does not yet support macOS 11 (Big Sur)" comments on various post e.g. Fink (suggested here). Is there anyone who
    has successfully managed to load and run gfortran on an M1 chip Macbook pro?

    Best,
    Pfesi

    Does anyone know if the newer ones are supposed to work on older OS X?

    GNU Fortran Version Tests
    7.4.0 on OS X 10.10
    ...

    But I might also try Spice 2g6 which is from 1983.



    For what it's worth, the gfortran-4.8.5 testsuite ie on a certain
    machine lasts one hour in 10.10 or 10.11, two in 10.13, and on a
    slightly newer MBPR running 10.14 lasts four hours. So, older
    OS X versions remain useful for certain tasks.

    I was able to install a native gfortran version with homebrew and as part of a conda-forge (miniforge) installation of M1 Python. FWIW, I saw runtimes of ~60% on a 2021 M1 laptop compared to a 2020 Intel laptop from our hybrid Python/Fortran code.
