Hi,
I am interested in parallel programming and I am using Code::Blocks for the same purpose.
I am using C programming language with OpenMp Directive. I am using Code::Blocks 8.02 with GCC compiler on windows XP platform. While compiling my program given below...
____________________________________________________________________
#include<omp.h>
#include<stdio.h>
int main (int argc, char *argv[]) {
int th_id, nthreads;
#pragma omp parallel private(th_id)
{
th_id = omp_get_thread_num();
printf("Hello World from thread %d\n", th_id);
#pragma omp barrier
if ( th_id == 0 ) {
nthreads = omp_get_num_threads();
printf("There are %d threads\n",nthreads);
}
}
return 0;
}
___________________________________________________________________
i am getting these errors..
C:\Documents and Settings\admin\My Documents\test\hi.c|1|omp.h: No such file or directory|
C:\Documents and Settings\admin\My Documents\test\hi.c||In function `int main(int, char**)':|
C:\Documents and Settings\admin\My Documents\test\hi.c|9|error: `omp_get_thread_num' was not declared in this scope|
C:\Documents and Settings\admin\My Documents\test\hi.c|13|error: `omp_get_num_threads' was not declared in this scope|
||=== Build finished: 3 errors, 0 warnings ===|

can anyone suggest me a solution in this regard...
I think the GCC version doesn't support the openmp directives. It would be better if someone suggest me to which version of GCC compatible with OpenMp commends to use with Code::Blocks
thanks in advance...
