hi friends,

i have a problem in using the OPENMP in Code::Blocks

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

int main (int argc, char *argv[])
int i;
int A[128], B[128],C[128] ;
for( i=0;i<128;i++)
{C[i]=0;A[i]=3;B[i]=2 ;}
omp_set_num_thread (4);
#pragma omp parallel
int id;
id = omp_get_thread_num();
for (i =id*8 ; i<(id+1)*8 ; i++)
C[i] = A[i]+ B[i] ;

the errors is : undefined reference to `omp_set_num_thread"
