The Mac OS M1 pre-built binary arrives with a /Library/Frameworks/R.framework/Resources/etc/Makevars containing
FLIBS = -L/Volumes/Builds/opt/R/arm64/gfortran/lib/gcc/aarch64-apple-darwin20.2.0/11.0.0 -L/Volumes/Builds/opt/R/arm64/gfortran/lib/gcc -L/Volumes/Builds/opt/R/arm64/gfortran/lib -lgfortran -lemutls_w -lm This is inconsistent with what is at said at the top of https://mac.r-project.org/libs-arm64/: that all binaries live in /opt/R/arm64, not /Volumes/Builds/opt/R/arm64. So no one would be able to build a source package containing Fortran without either modifying Makevars or creating symbolic links. -Naras [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
