Winsock重新定义错误 [英] Winsock redefinition errors

问题描述

我正在用Visual C ++ 2010编译一个项目，但是某些Winsock重新定义存在问题.

I am compiling a project in Visual C++ 2010, but I have problems with some Winsock redefinitions.

首先我得到:

syntax error : identifier 'SOCKADDR_STORAGE'

但是，如果我包含winsock或winsock2或ws2tcpip，则会出现许多类似以下错误:

But if I include winsock or winsock2 or ws2tcpip i get many errors like these:

error C2011: 'sockaddr' : 'struct' type redefinition 
error C2011: 'WSAData' : 'struct' type redefinition
error C2011: 'linger' : 'struct' type redefinition

推荐答案

您的问题是，通过包含Windows.h，您也已经包含了winsock.h.这是您的问题出现的原因，因为包含winsock2.h或ws2tcpip.h会尝试重新定义winsock.h

Your problem is that by including Windows.h, you are also already including winsock.h. It is here your problem arises as including winsock2.h or ws2tcpip.h will attempt to redefine some of the definitions in winsock.h

在包含Windows.h之前使用#define WIN32_LEAN_AND_MEAN，可以阻止编译器包含Windows.h附带的很多额外内容

By using #define WIN32_LEAN_AND_MEAN before your Windows.h include you stop the compiler from including a lot of the extra stuff that comes with Windows.h
