[LLVMdev] LLVM-clang with opennp

Greetings,

so I tried to use opennp with one of the latest version of clang, clang
version 3.4.2 (tags/RELEASE_34/dot2-final). Followed the procedure to
compilre and export the library PATHs, Compiling my hello.c using :

clang -fopenmp hello.c

and then running it, still it can't use more than 1 thread:

Bash-4.1$ ./a.out Hello from thread 0, nthreads 1

I tried to manually export export OMP_NUM_THREADS=8 but that didn't solve
anything as well.

Any suggestions would be appreciated.


-Amir


p.sl: This is the hello.c:

#include <omp.h>#include <stdio.h>int main() {#pragma omp parallel
printf("Hello from thread %d, nthreads %d\n", omp_get_thread_num(),
omp_get_num_threads
