错误C2065：&＃39; mClock&＃39;：未声明的标识符 [英] error C2065: 'mClock': undeclared identifier
问题描述
我知道我已经在renderer.h文件中声明了'mClock'。为什么现在说它在我的renderer.cpp文件中链接到头文件时未定义。这可能是因为我需要在范围内声明它。有人可以给我一个
的例子吗？
I understand that I have already declared 'mClock' in my renderer.h file. Why is it now saying it is undefined in my renderer.cpp file when it is linked to the header file. Could this be because I need to declare it in the scope.. Could someone give me an example of this?

推荐答案
似乎
渲染构造函数，析构函数等在
wWinMain 函数中显示不正确。将它们放在此功能之外。
Seems that the Rendering constructor, destructor, etc., appear incorrectly inside the wWinMain function. Place them outside this function.
