I am trying a basic openmp program on mac osx. I am on Mavericks and have the latest Xcode.

#include <cmath>
int main()
{
        const int size = 256;
        double sinTable[size];

        #pragma omp parallel for
        for(int n=0; n<size; ++n)
                sinTable[n] = std::sin(2 * M_PI * n / size);

        // the table is now initialized
}

When I compile the code from terminal as g++ Test.cpp -fopenmp, I get the following error:

ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)

How should I fix this?

Thanks

The latest Xcode does not include gcc. g++ is a file that runs clang, which does not include OpenMP – mmmmmm Feb 12 '14 at 22:50
@Mark Thanks. So how should I fix this? – John Smith Feb 12 '14 at 22:50
See the duplicate but you need to install another compiler – mmmmmm Feb 12 '14 at 22:52
