Delete Function error

I have been making a shooter game for fun, and it is not working. I have made few libraries that is of my own. However, it is giving me problemes with the delete function, and if I take them out, I start to have bunch of linker errors that confirms me that delete function is needed...

#include <cstdlib>
#include <time.h>
#include "Character.h"
#include "Ship.h"
#include "Laser.h"
