我在我的项目中使用了很多包含（但每个头文件都使用像

#ifndef _HEADER_H 
#define _HEADER_H
...
#endif

现在我从 ws2ipdef.h 得到这个错误（自动包含在 windows.h 中）：

c:\program files\microsoft sdks\windows\v7.0\include\ws2ipdef.h(336) : error C2146: syntax error : missing ';' before identifier 'IN6_ADDR_EQUAL'

在 Interface.h （包含在其他一些文件中）我使用：

#define WIN32_LEAN_AND_MEAN

// sockets
#include <winsock2.h>
#include "windows.h"
#include <ws2tcpip.h>

我该如何解决这个问题或任何提示？

谢谢

尝试使用#pragma once而不是 ifndef 保护，它指定编译器在编译源代码文件时只包含（打开）一次文件。http://msdn.microsoft.com/en-us/library/4141z1cx.aspx

在 Interface.h 中使用额外的 ifndef 保护解决了它

#ifndef _READERCOMMUNICATION_H
#define WIN32_LEAN_AND_MEAN // to exlude some unnecessary windows headers (see windows.h)

// sockets
//#include <winsock2.h> // winsock 1 is enough for my project
#include <windows.h>
#include <ws2tcpip.h>
#endif
