Hello

I'm trying to compile this simple program

#include <stdio.h>
#include <math.h>

int main(void)
{
  float r=2;

  printf("A raiz de %2.0f e' %.6f", r, sqrt(r));

  return 0;
}

but i get the following errors.

/tmp/cca110161.o: In function `main':
/tmp/cca110161.o(.text+0x17): undefined reference to `sqrt'

I belive it's easy to solve but i have no one nearby to help
me. Thanks in advance.
