I did what you asked but its not giving the exact func names ..the
second command gprof -z -b b >file2 ,i think is creating problem ....I
also tried gprof for the follownig c program :
#include<stdio.h>

static void static_func()
        {
        printf(" inside static function ");
        }


void f_called()
        {
        printf(" in f_called ");
        }
void f_not_called()
        {
        printf(" in f_not_called ");
        }

void Func_calling_static()
        {
        printf("\n in Func_calling static");
        static_func();
        }



/*void extern_func()
        {
        printf("\nhello");
        }
*/


int main()
        {
        static_func();
//        extern_func();
        f_called();
        Func_calling_static();
        return 0;
        }

Flat profile:

Why f_called is not listed in the call graph ?
