I'm trying to get OpenMP programs to compile using CB.  I read previous OpenMP discussions on this forum, written about 7 years ago.  However, I did not understand what they were talking about, and i'm sure CB has changed since 2010.  Does anyone know what i need to click, what settings i need to change, so that my OpenMP programs will compile?  I get error messages when i try to compile simple five line programs.  Thanks,
Edward

Thanks, but just too complicated for me.

If using a project and posting a build log is too complex for you.
Then, using OpenMP is likely too complex for you, at least till you can do both of those items.

oh sorry, i didn't know you wanted to see the build log.  Here is the program, and build log.  I'm using Windows 7.

#include <stdio.h>
#include <stdlib.h>
#include <omp.h>

void hello();

int main()
{
   int threadCount = 4
   #pragma omp parallel num_threads(threadCount)
   hello();

   return 0;
}

void hello(){

   int myRank = omp_get_thread_num();
   int threadCount = omp_get_num_threads();
   printf("thread %d of %d\n", myRank, threadCount);
}
