"Hi!
I'm trying use openmp with xcode 9 using c++. I did this steps.
- Install clang-omp using homebrew:
.brew install llvm - Add llvm binaries to your path using :
.echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile - Create a new Xcode project.
- Under Build Settings
- Add a new user-defined setting CC with the value
/usr/local/bin/clang-omp - Add
to Other C Flags-fopenmp - Add
to Header Search Paths/usr/local/include - Set Enable Modules (C and Objective-C) to
.No
- Add a new user-defined setting CC with the value
- Under Build Phases
Add
to Link Binary With Libraries/usr/local/lib/libiomp5.dylib
Done. You can now
#include <libiomp/omp.h>and start using
#pragma omp ...in your source code.
I checked all directories and files and all it exits, but when i try include the library <libiomp/omp.h> xcode say me " 'libiomp/omp.h' file not found ". And when i run the program i have this error. Apple LLVM 9 error: cannot specify -o when generating multiple output files:
