AFAICT, Spencer followed the implied instructions and it still didn't work.

There may also be a PATH issue when upgrading to 4.3.x, /usr/local -> 
/opt/R/<arch> Does gfortran 12.2 install to /opt/R/.../bin ?


          The default install went to "/opt/gfortran", and gcc is in "/usr/bin".


          What should I do to fix this?


I downloaded and reinstalled "gfortran-12.2-universal.pkg". I did NOT see an option to install it anyplace else.


          Thanks,

Already answered to you and on R-pkg-devel [9 mins after you posted there - now

To quote from the page you downloaded R from:

This release uses Xcode 14.2/14.3 and GNU Fortran 12.2. If you wish to compile R 
packages which contain Fortran code, you may need to download the corresponding GNU 
Fortran compiler from https://mac.R-project.org/tools 
<https://mac.r-project.org/tools>.

Hello, All:


          "R CMD check KFAS" under macOS 11.7.8 (the latest version that will run on my 
aging Mac) complains "gfortran: command not found".


          I just upgraded to R 4.3.1 and installed "gfortran-12.2-universal.pkg" per 
"https://cran.r-project.org/bin/macosx/tools/";.  I expected this to solve the problem.  
It didn't.


          Suggestions?
          Thanks,

p.s.  This is my fork of KFAS, available at "https://github.com/sbgraves237/KFAS";.
