Roy, For R 4.0.0, there is no need to keep Makevars or Renviron's PATH configuration as everything should just "work." The R 4.0.0 binary will look at the default installation location for OS-specific gfortran8.2 or gfortran6.3 version.
Having said this, there is also the OpenMP opt-in possibility for developers (avoid users) detailed here: http://mac.r-project.org/openmp/ Best, JJB On 5/26/20, 2:00 PM, "R-SIG-Mac on behalf of Roy Mendelssohn - NOAA Federal via R-SIG-Mac" <r-sig-mac-boun...@r-project.org on behalf of r-sig-mac@r-project.org> wrote: Hi All: Awhile back Simon posted what if anything should be in your Makevars for R4.0.0 if you needed to compile packages from source. I thought I had saved that email but i can't find it, and I just looked at the archives and can't find it either. If anyone has that info I would appreciate it. I know you remove all the clang references that might have been there, I have kept the gfortran to gfortran8.2, is there anything else.
