我得到的错误是对statesavegamemenu()和stateloadgamemenu()的未定义引用。据我所知,像这样的链接器错误与程序无法找到相关函数的定义有关,但我非常清楚地实现了它们,所以我很困惑为什么会发生这种情况,以及任何帮助不胜感激。

在保存游戏和加载游戏中你忘记这样做,所以它与呼叫不匹配
state statesavegamemenu(string fname, string lname, string filename,
ofstream outFS)
{
到
state statesavegamemenu(string fname, string lname, string filename,
ofstream& outFS)
{
与其他功能相同,但ifstream而不是ifstream&amp;
