However, I would like my R package on github to be used by more users, and since it relies on openMP, I am losing that audience.Ĭan someone provide the necessary steps to set up R on mac in a way that it can compile Rcpp code with openMP? I'd like to turn that into a quick tutorial.ĮDIT: I should have added - on Apple Silicon, because there are some extra confusions where things go - /usr/local vs /opt
I am not a mac user, but it seems to me that setting up a mac to compile Rcpp packages or code snippets with openMP seems to be too difficult for most mac users. I came across other ideas, including compiling llvm yourself, using homebrew or macports to install R and/or llvm and/or gcc, and then figuring out how to use the right compiler and/or flags with (R)cpp.
The ability to use OpenMP without a custom setup. Unfortunately, with R 4.0.0 the CRAN distributed version of R loses There's probably a gazillion threads on OSX+Rcpp+openMP, but the bottom line right now appears to be this (per coatless):
