Hello.

I am trying to compile the following code

  1 #include <stdio.h>
  2 #include <math.h>
  3 int main (){
  4         double a = 0.0;
  5         double b = pow (10,a);
  6         return 1;
  7 }

while I was given the following error message

caojun@ubuntu:~/homework$ gcc -o test.out utility.c
/tmp/ccOQV3cx.o: In function `main':
utility.c:(.text+0x27): undefined reference to `pow'
collect2: ld returned 1 exit status

My gcc pakages
                gcc-4.1
                gcc-4.1-multilib
                gcc-4.2

Can anyone help me please?

Sincerely
Cao Jun
