The output should look like this * installing *source* package ‘cluster’. Test the changes by calling install.packages("cluster", type = "source") It is likely that one will not need the workaround presented below in the future since it will probably be fixed in the R installer at some point (hopefully).Ĭreate a file ~/.R/Makevars (if it does not exist yet)Īdd the following to ~/.R/Makevars FC = usr/local/opt/gcc/bin/gfortran So how does one now install gfortran on macOS these days? There was a discussion about these changes in the homebrew PR, but the comments that highlighted potential issues seem to have gone unnoticed.Īlso, some workarounds posted in the thread do not work.

This was fulfilled by the old gfortran cask but is not by the new gcc integration. The issue after the integration of gfortran into the gcc formula is that the official R binary installer for macOS expects the gfortran installation at /usr/local/gfortran. However, in some cases, when calling install.packages(), a working gfortran installation is needed.Īnd if type = "source" is used, it needs to be there. These do not require a working gfortran installation. This requirement does not occur very often, as most users install R package binaries on macOS. Unfortunately, this change did not result in a smooth experience for R users who want to compile packages from source that require a functional gfortran compiler. However, this is not a long-term approach, and usually, one would like to do this via brew, the most popular package manager for macOS. Now, one could go to and manually install the respective. The cask was removed in December 2020 and merged into the gcc formula (which can be installed via brew install gcc). Only new users who want to install gfortran this way, will get the message that the cask is “not available”. Users who have installed this cask already, will not notice since things will continue to work as normal.
