Additional information:
I have compiled this program with gcc -fopenmp topenmp.c
(in 32 and 64 bit mode).
#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());
}
and it runs without error (2 threads).
