[libcaca] undefined reference

[BlackCode <[[REDACTED]]@gmail.com>]

I've a stupid problems when compiling this simple code:

/*

 * authors                blackcode
 * email                  [[REDACTED]][at]gmail[dot]com

 * description:
 * a basic example about the use of libcaca
 */
#include <cucul.h>
#include <caca.h>
int main(void)
{
	int x,y;
	x=0; y=0;

	cucul_canvas_t *cv; caca_display_t *dp; caca_event_t *events;
	cv = cucul_create_canvas(80,24);

  if(!cv)
  {
  	printf("errore nella creazione di canvas!\n");
	return 1;
  }

  dp = caca_create_display(cv);
  if(!dp)
  {
  	printf("errore nella creazione del display!\n");
	return 1;
  }

  caca_set_display_title(dp, "example 1");
  cucul_set_color_ansi(cv, cucul_black, cucul_white);
  cucul_put_str(cv, 40, 12, "this is a message");
  caca_refresh_display(dp);
 while(1)
 {
 caca_event_t ev;
 int ret = caca_get_event(dp, caca_event_any, &ev, -1);
 if(!ret)
 	continue;

 if(caca_get_event_type(&ev) & caca_event_mouse_motion)
  {
	
	x=caca_get_event_mouse_x(ev);
	y=caca_get_event_mouse_y(ev);

  }

  caca_refresh_display(dp);
  cucul_put_str(cv, x,y, "lo0o00oo0ol");
}
 caca_free_display(dp);
  return 0;

}
