初次用RT-GUI调用rtgui_win_create()时不成功,不知道是那里出问题了

用了RT-GUI的v0.6.2
执行了下面的代码，

```static void led_thread_entry(void* parameter)
{
	  struct rtgui_app* app;
	  struct rtgui_win *win;
	  struct rtgui_label *label;
		struct rtgui_box *box;
	
	  struct rtgui_rect rect = {10, 50, 200, 250};
	
	  app = rtgui_app_create("MyApp");
	  RT_ASSERT(app != RT_NULL);
	
	  win = rtgui_win_create(RT_NULL, "MyWindow", &rect, RTGUI_WIN_STYLE_DEFAULT);
	
	  box = rtgui_box_create(RTGUI_ORIENTATION_BOTH, 10);
	  rtgui_container_set_box(RTGUI_CONTAINER(win), box);
	
	  label = rtgui_label_create("Hello World");
	  rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(label));
	
	  rtgui_container_layout(RTGUI_CONTAINER(win));
	
	  rtgui_win_show(win, RT_FALSE);
	
	  rtgui_app_run(app);
	
	  rtgui_win_destroy(win);
	  rtgui_app_destroy(app);
	  rt_kprintf("MyApp Quit.
");

}```

RTGUI: creating the server app 200017bc.

create win: MRTGUI: creating the server app 200022d4.
RTGUI: create server: 200022d4 server: 200022(container != RT_NULL) assert failed at rtgui_container_add_child:212

到了 rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(label));
这里就被failed 了
查了下发现是 win = rtgui_win_create(RT_NULL, "MyWindow", &rect, RTGUI_WIN_STYLE_DEFAULT);这里win返回了RT_NULL,引起的。
请问，还需要做什么设置，才可以正常执行它
