Sorry, but with this tiny program i have the same error : Operation not 
permitted. What is wrong ?

  err = rt_cond_signal(&cond);
  if(err != 0){
    printf("\nrt_cond_signal : %s",strerror(-err));
  }
         

}

int main (int argc, char **argv)
{

  mlockall(MCL_CURRENT | MCL_FUTURE);
   
  rt_timer_set_mode(TM_ONESHOT);

  err = rt_cond_create(&cond,"condition");
  if(err != 0){
    printf("\nrt_cond_create : %s",strerror(-err));
  }
  err = rt_mutex_create(&mutextest,"mut");
  if(err != 0){
    printf("\nrt_mutex_create : %s",strerror(-err));
  }
 
  err = rt_task_create(&task,"SecondTask",0,99,0);
  if(err != 0){
    printf("\nrt_task_create : %s",strerror(-err));
  }
  err = rt_task_start(&task,&mytask,NULL);
  if(err != 0){
    printf("\nrt_task_start : %s",strerror(-err));
  }
 
 
  err = rt_cond_wait(&cond,&mutextest,TM_INFINITE);
  if(err != 0){
    printf("\nrt_cond_wait : %s",strerror(-err));
  }
  printf("\nend \n");
 
  retrurn(0);

}
