title: Undefined reference to `omp_get_max_threads_'
body: <p>I'm getting the following errors trying to compile a project:
  (fortran, using gfortran)</p>
  <blockquote>
  <p>undefined reference to `omp_get_max_threads_'</p>
  <p>undefined reference to `omp_get_thread_num_'</p>
  </blockquote>
  <p>Problem is, my GCC version is 4.4.3, which was suppose to support OpenMP.</p>
