Instructions for using clang-omp with XCode 9

[alk3ovation]

I've updated the instructions for using clang-omp with XCode 9.

Using OpenMP with XCode 9

1. Install clang-omp using homebrew: brew install llvm.
2. Add llvm binaries to your path using : echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile.
3. Create a new Xcode project.
4. Create a symlink - /usr/local/bin/clang-omp -> /usr/local/Cellar/llvm/5.0.0/bin/clang
5. Create a symlink in the same directory - clang++-omp -> /usr/local/Cellar/llvm/5.0.0/bin/clang++
6. Under Build Settings
   A. Add a new user-defined setting CC with the value /usr/local/bin/clang-omp ->
   B. Add -fopenmp to Other C Flags
   C. Add /usr/local/include to Header Search Paths
   D. Set Enable Modules (C and Objective-C) to No.
   E. Set Enable Index-While-Building Functionality to No
7. Under Build Phases
   A. Add /usr/local/lib/libiomp5.dylib to Link Binary With Libraries

Hi, I don't think we need to update the instructions. clang-omp is discontinued, you'd better to use official clang/llvm. Moreover, you an use Apple's clang to compile OpenMP programs. Though they disabled driver's -fopenmp option, you can use the frontend option this way: clang -Xclang -fopenmp <your_program> -L <path to libomp> -lomp

Where can one find a compiled version of OpenMP to link with your command:

clang -Xclang -fopenmp <your_program> -L <path to libomp> -lomp
