任何想法可能會導致此？
編輯：
main_display.h：
#pragma once
#include <allegro5/allegro.h>
#include <stdio.h>
#define SCREEN_W 640
#define SCREEN_H 480
extern ALLEGRO_DISPLAY *main_display = NULL;
void display_init();
void destroy_display();
event_queue.h
#pragma once
#include <stdio.h>
#include <allegro5/allegro.h>
#include "main_timer.h"
#include "main_display.h"
extern ALLEGRO_EVENT_QUEUE *event_queue = NULL;
void event_queue_init();
void event_queue_destroy();
