Wth?


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

int main()
{
    double phi = (1 + sqrt(5))/2;
    int n = 12;
    n = (pow(phi,(double)n) - pow((1 - phi),(double)n))/sqrt(5);
    printf("%d \n", n);
}

gcc --std=c99 name.c

undefined reference to 'pow'
undefined reference to 'pow'

gcc name.c

undefined reference to 'pow'
undefined reference to 'pow'

What am I doing wrong? The standard library is install and the man pages do have a description of double pow(double, double)

>>11
check 'em doubles

Ye Olde Devcpp and Code::Blocks compile it just fine...

RTFM, dumbass.
