Those are binaries used by CRAN and are built using the recipes system, thus can be transparently re-built accordingly. bzip2 may need to be installed if the system version is too oldīinaries for the above libraries are available from the /bin directory for the builds we use.PCRE2 built with -disable-jit (JIT is buggy on macOS).This is no longer the case, the following libraries are not present in most recent macOS (or are too old) and have to be installed before R can be compiled: Old versions of R provided fall-back versions of dependend libraries. If you choose one of those package managers, make sure you compile everything using those tools including R and all packages and libraries you intend to use.Īdditional information on the OpenMP page is available for those interested in OpenMP support which is not supported by Apple, but still possible with additonal libraries. Although it is possible to compile R using tools from other package managers such as Homebrew, MacPorts or Fink, such binaries are by definition incompatible with macOS native libraries and applications. NOTE: In order to retain compatibility with native R we recommend using above tools. 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. In order to compile R for macOS, you will need the following tools:
