警告 C4003：宏“min”的实际参数不足

Question

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

这个头文件中的内联宏定义为：

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

无论如何，我在这里阅读了许多讨论这个问题并表明我可以使用的帖子

#define NOMINMAX before #include "windows.h"

但是这不起作用，我仍然得到错误。我不想修改库，因为它很大，我不想让我的项目依赖于自定义库，所以我更喜欢我可以在我的 dll 代码中处理的某种解决方案。我还能做什么？

也许您在直接包含“windows.h”之前放置了#define NOMINMAX，而不是在包含它的其他标题之前？尝试将它移动到源文件的同一开头（如果没有）。
