Apple kind of messed things up for openmp by forcing creating a symlink called clang to gcc... and broke some functionality. This stackoverflow has more information. If you get the proper version it will work. In the mean time I may need to rewrite without openmp.

Have you tried RcppParallel?

BTW, from my reading of WRE I would think you have to add suitable compiler flags to enable OpenMP.

For people using MacPorts instead of homebrew - use +top_level variant to add "omp.h" to /libs/

sudo port install libomp +top_level
