编译出错，急寻帮助

[straywithsmile]

由于情况复杂，我也只能大概说一下

我有Building和Controller两个类，然后我再Building的h里已经包含了Controller的h文件，然后在Building类里申明一个Controller型的成员变量，可是编译的时候编译器老是提醒我Controller未定义，请问一下这到底是怎么回事！！！

来点代码看看。

原来是坐电梯模拟的。

把class Controller也贴一下。

注意笔误，大小写等
文件是否insert到工程中

[level1979]

在 controller中添加Biulding 申明 class Biulding;

[straywithsmile]

肯定没有笔误，检查过很多次了，而且肯定insert到工程中了

[straywithsmile]

我试过，声明为友元，申明为友元的地方不会报错，可是用的地方却会

[kelinwang19]

用extern试试

[straywithsmile]

我用的不是全局变量，extern好像不行吧
