WinSock2.h中的重新定义错误 [英] redefinition errors in WinSock2.h

问题描述

在项目文件中包括winsock2.h.

Including winsock2.h, in a file of a project.

在-
中遇到许多错误 WinSock2.h(109) : error C2011: 'fd_set' : 'struct' type redefinition
与相应的-
WinSock.h(54) : see declaration of 'fd_set'

Getting many errors in -
WinSock2.h(109) : error C2011: 'fd_set' : 'struct' type redefinition
with a corresponding -
WinSock.h(54) : see declaration of 'fd_set'

我看不到任何头文件中包含winsock.h.

I don't see winsock.h included in any of the headers.

项目中是否有任何设置可能会导致这种情况?

Are there any setting in the project that may be causing this?

但是，我在另一个文件中使用windows.h:

EDIT
However, I am using windows.h in another file:
http://cboard.cprogramming.com/windows-programming/41212-strange-msvc-winsock2-compile-error.html

在标题中，我有:

EDIT 2
In the header I have:

#include <winsock2.h>  
#include <iphlpapi.h>
#include "\MyFiles\FileX.h" <-which #include <windows.h> 

推荐答案

我的有根据的猜测是包含标头的顺序，即首先包含winsock2.h(在windows.h之前具有第一个含义)，或者在包含<前将WIN32_LEAN_AND_MEAN定义为windows.h，可防止Windows.h包含Winsock v1.

My educated guess would be the order of included headers, i.e. include winsock2.h first (with first meaning before windows.h), or define WIN32_LEAN_AND_MEAN before including windows.h, which prevents windows.h from including winsock v1.

#include <winsock2.h>
#include <windows.h>

-或-

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <winsock2.h>
