Dear all, Lack of OpenMP support in Apple’s build of Clang is cited as one reason for not using it in CRAN builds, but this is only partly true: after installing libomp from Homebrew, I have been adding “-Wp,-fopenmp” to CXXFLAGS and CFLAGS (and “-lomp” to LIBS) to my builds for a while, and everything seems to work OK.
I’m not sure how far back this support goes (and I haven’t tried the Xcode 11 tools yet), but is there any known reason not to take this approach, and if not, would it make sense for R’s configure script to try “-Wp,-fopenmp” when testing for OpenMP support?
