Installing gfortran on macOS v12.2

Installing gfortran on macOS v12.2

[Harold Corwin]

Hi, folks,

I've recently bought a new iMac with Apple's M1 chip running macOS 
Monterey (v12.2).  I'd like to install gfortran on this machine, but so 
far have not had much luck beyond successfully (I hope!) installing Xcode.

There is a lot online that could help, but I've not yet been able to 
sift through it to the page(s) that I need.  So, is there a web page 
with step-by-step instructions for getting gfortran going on a machine 
like my new one?  I'm more or less familiar with UNIX and have used VAXs 
and Macs pretty happily for nearly 40 years -- but the system's guys 
have have always taken care of the gcc installation in the past!  Now 
that I'm my own "system's guy", I find that I need a little help with 
the details.

Thanks!
Harold Corwin

I think you should probably use Homebrew https://brew.sh/
