I am using Mac OS X Sierra, and I found that clang (LLVM version 8.1.0 (clang-802.0.38)) does not support OpenMP: when I run
clang -fopenmp program_name.c, I got the following error:
clang: error: unsupported option '-fopenmp'
It seems that clang does not support
I could not find any openmp library in homebrew. According to LLVM website, LLVM already supports OpenMP. But I could not find a way to enable it during compiling.
Does this mean that the default clang in Mac does not support OpenMP? Could you provide any suggestions?
(When I switch to GCC to compile the same program (gcc is installed using
brew install gcc --without-multilib), and the compilation is successful.)
