I'm sure i'm doing something really basic and stupid here, but i can't
seem to use pow() from math.h ???
ben:1$ cat test_pow.c
#include <math.h>
int main()
{
double temp;
temp = pow( 2.0, 3.0 );
return 1;
}
ben:2$ cc test_pow.c
/tmp//ccy24322.o(.text+0x31): In function `main':
: undefined reference to `pow'
collect2: ld returned 1 exit status
