Dear Mac users,
<snip>
Package developers, please check the CRAN result pages for your
package to make sure it passes checks. Also please note that we are
now using a universal GNU Fortran compiler that works both on Intel
and arm64 Macs - you can download an Apple Installer from
https://mac.r-project.org/tools/
I have GNU Fortran (GCC) 12.0.1 20220312 (experimental)
in /opt/R/arm64/gfortran/bin/gfortran
Should it be uninstalled/removed in some way before installing
gfortran-12.2-universal.pkg, and if so, how?
Not necessary, as the newer compiler installs into /opt/gfortran. You
may need to change FC and FLIBS in a ~/.R/Makevars if you use one, and
you may need to adjust your path if you use Fortran other than for R
packages.
To remove the older version, delete /opt/R/arm64/gfortran/ .
