为什么包含Windows.h时std :: min失败？ [英] Why is std::min failing when windows.h is included?

问题描述

#include <algorithm>
#include <Windows.h>

int main()
{
    int k = std::min(3, 4);
    return 0;
}

如果包含Windows.h，Windows在做什么？我无法在Visual Studio 2005中使用 std :: min 。错误消息是：

What is windows doing if I include Windows.h? I can't use std::min in visual studio 2005. The error message is:

error C2589: '(' : illegal token on right side of '::'
error C2059: syntax error : '::'

推荐答案

windows.h 头文件（或更正确地说，依次包含的 windef.h ）具有 min 和 max

The windows.h header file (or more correctly, windef.h that it includes in turn) has macros for min and max which are interfering.

在包含它之前，您应该 #define NOMINMAX 。

You should #define NOMINMAX before including it.
