Installing gfortran
Hi G?ran ``` curl -O https://mac.r-project.org/libs-arm64/gfortran-f51f1da0-darwin20.0-arm64.tar.gz sudo tar fvxz gfortran-f51f1da0-darwin20.0-arm64.tar.gz -C / ``` should do it. See also https://pat-s.me/transitioning-from-x86-to-arm64-on-macos-experiences-of-an-r-user/#gfortran or https://cynkra.com/blog/2021-03-16-gfortran-macos/ for more information. Cheers Patrick

Trying gfortran-f51f1da0-darwin20.0-arm64.tar.gz from https://mac.r-project.org/libs-arm64/ (following instructions), download and unpack, but no sight of gfortran in /opt/R/arm64/bin so the building of my package fails. clang -arch arm64 -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I/opt/R/arm64/include -fPIC -falign-functions=64 -Wall -g -O2 -c c2f.c -o c2f.o /opt/R/arm64/bin/gfortran -mtune=native -fno-optimize-sibling-calls -fPIC -Wall -g -O2 -c chek.f -o chek.o make: /opt/R/arm64/bin/gfortran: No such file or directory make: *** [chek.o] Error 1 Of course, there is a warning on that web page (so why the link to it?) saying that IMPORTANT: All binaries are moving to a unified repository under /bin/darwin<ver>/<arch> with manifest file to simplify automated installataion. Go to /bin/darwin20/arm64 for latest Big Sur arm64 binaries. The following is only kept for legacy access. but there I cannot identify (by name) any file that could contain a fortran compiler. To summarize: I need help. Thanks, G?ran
