That is probably true for FreeBSD 10, since clang 3.4 in base doesn't support OpenMP. Even though <omp.h> and libgomp are present in FreeBSD 10, and using base clang to compile the test program here <http://openmp.org/wp/openmp-compilers/> succeeds, the resulting executable only runs one thread. There is probably more hope for FreeBSD 11 if the runtime is imported, since clang 3.6 in base there at least knows about the -fopenmp option. > I'm not fond of lang/gcc as openmp "provider": if a port use c++, it > will cause linkage headaches with libc++ (I never was able to have > graphics/darktable working, for example). You might want to try out lang/clang-devel with devel/libiomp5-devel.
