Hi Watchapon, I just wanted to provide an additional workaround for OS X users. There is an active clang-omp compiler that is available outside of the Apple provided clang compiler. I believe work on clang-omp is being spearheaded by a couple of developers at Intel. You can grab clang-omp from https://clang-omp.github.io/ or if you have the homebrew package manager <https://brew.sh/> installed, you can install it simply via brew install clang-omp. Then under [backend-openmp] set cc = clang-omp.
