How to use glutBitmapCharacter - opengl

Question

I'm trying to write fonts on my SDL's window and glutBitmapCharacter.
But I'm failling to compile it.
My compilator error message is :
undefine reference to « glutBitmap9By15 »
undefine reference to « glutBitmapCharacter »
This code :
#include <SDL/SDL.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>
#include <cstdlib>
#include <cmath>
#include <string>
#include <iostream>
int main()
{
SDL_Init(SDL_INIT_VIDEO);
atexit(SDL_Quit);
SDL_SetVideoMode(WIDTH, HEIGHT, 32, SDL_OPENGL);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(0,WIDTH,0,HEIGHT);
SDL_EnableKeyRepeat(100,100);
glMatrixMode(GL_PROJECTION);
glPushMatrix();
glLoadIdentity();
gluOrtho2D(0.0, WIDTH, 0.0, HEIGHT);
glMatrixMode(GL_MODELVIEW);
glPushMatrix();
glLoadIdentity();
glColor3f(0.0, 1.0, 0.0); // Green
glRasterPos2i(10, 10);
std::string s = "Respect mah authoritah!";
void * font = GLUT_BITMAP_9_BY_15;
for (std::string::iterator i = s.begin(); i != s.end(); ++i)
{
char c = *i;
glutBitmapCharacter(font, c);
}
glMatrixMode(GL_MODELVIEW);
glPopMatrix();
glMatrixMode(GL_PROJECTION);
glPopMatrix();
}
Does someone know what I have to do to make it work ?
Thanks
