CRAN High-Sierra builds currently use GNU Gortran 8.2 from that page (note that even though compiled for Mojave it is compatible with High Sierra). We recommend the official GNU Fortran binaries from F.X.Coudert.

Unfortunately Xcode doesn't contain a Fortran compiler, therefore you will have to install one.ĭepending on the type of your Mac (old Intel Macs vs new arm64-based Apple silicon Macs) we recommend the following options: R and some contributed package require a FORTRAN compiler.

Which installs Xcode command line tools which are sufficient to build R (however, if you want to also build the R.app GUI you do need the full Xcode installation).

On modern macOS versions you can simply use Older versions are available in the 'more' section of the Developer pages (Apple developer account necessary). Xcode can be obtained from Apple AppStore and the Xcode developer page. There might be another way, but this is how I did it.In order to compile R for macOS, you will need the following tools:

Once downloaded, install it as any other .dmg package.

Press the link on the right side and wait for download to complete.

Search for the command line package you want to download (I'm going to use the latest stable Command Line tools for Xcode 10 and macOS Mojave).

It is a small package of ~183Mb which I think it's enough to be downloaded via your browser. This just happened to me and I'm writing this as a note-to-self but also to share this with others who might be facing a similar situation. xip file while using a browser, regardless of which one it is, can be a pain when your connection is not as stable and fast as others' and when the download can be interrupted at any time and you're most likely going to have to restart the whole download. Downloading Xcode from the App Store, or even the.
