c++ - 警告 C4003 : not enough actual parameters for macro 'min'

Question

我正在使用 C++ 编写 ATL COM dll，当我尝试使用一个库时，我遇到了一些与最小值/最大值相关的错误，例如这个。它似乎也导致了许多其他错误，尽管我认为它们与此有关。

此 header 中的内联宏定义为:

    /// smallest positive
    inline static const DPosition
    min()
    {
      return DPosition(std::numeric_limits<typename DPosition::CoordinateType>::min());
    }

无论如何，我已经阅读了这里的许多讨论这个问题的帖子并表明我可以使用

#define NOMINMAX before #include "windows.h"

但是这不起作用，我仍然收到错误。我不想修改库，因为它很大，我宁愿不必让我的项目依赖于自定义库，所以我更喜欢某种我可以在我的 dll 代码中处理的解决方案。我还能做什么？

也许您将#define NOMINMAX 放在直接包含“windows.h”之前，而不是放在其他包含它的头文件之前？尝试将其移动到源文件的同一开头(如果没有)。
