That said, the binary target for CRAN has been announced on this list as part of the big-sur build announcement: https://stat.ethz.ch/pipermail/r-sig-mac/2023-April/014731.html > For reference the R-on-macOS FAQ I consulted still talks about 10.13 at > https://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#Installation-of-source-packages > > CC = clang -mmacosx-version-min=10.13 > CXX = clang++ -mmacosx-version-min=10.13 -std=gnu++14 > FC = gfortran -mmacosx-version-min=10.13 > OBJC = clang -mmacosx-version-min=10.13 > OBJCXX = clang++ -mmacosx-version-min=10.13 > > so someone may want to refresh this. It is what I consulted as relevant info. > It says "Look at file /Library/Frameworks/R.framework/Resources/etc/Makeconf" so it is just an example that will vary by build. For example big-sur-arm64 will give you $ grep -E '^(CC|CXX|FC|OBJC|OBJCXX) ' /Library/Frameworks/R.framework/Resources/etc/Makeconf CC = clang -arch arm64 CXX = clang++ -arch arm64 -std=gnu++14 FC = /opt/R/arm64/bin/gfortran -mtune=native OBJC = clang -arch arm64 OBJCXX = clang++ -arch arm64 Again, this is just an example, no one should be entering such flags by hand - that's why they are in Makeconf so packages can use them without worrying about the values (see R-exts 1.2: https://cran.r-project.org/doc/manuals/R-exts.html#Configure-and-cleanup for details).
