cygwin + Windows套接字编程 [英] cygwin + Windows socket programming

问题描述

我正在尝试学习Windows中的Socket编程，并且正在使用cygwin.我发现，所需的相同文件位于/usr/include/w32api/.

I am trying to learn Socket programming in Windows and am using cygwin for the same. I found out that the required files needed for the same were at /usr/include/w32api/.

我从net处获取了一个示例程序，并尝试进行编译，但无法这样做....相同的代码是

I took a sample program from net and tried to compile but was unable to do so.... The code for the same is

 #include <w32api/windows.h>
 #include <w32api/winsock.h>
 #include <stdio.h>
  int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmd, int nShow)
  {

       WORD sockVersion;
           WSADATA wsaData;
           int nret;

        sockVersion = MAKEWORD(1, 1);           // We'd like Winsock version 1.1

        // We begin by initializing Winsock

        WSAStartup(sockVersion, &wsaData);

       // rest part of code
   }

我在cygwin环境中使用gcc-3进行编译，并得到了非常奇怪的错误.....

I compile it using gcc-3 in cygwin environment and get very strange errors .....

undefined reference to '_WSAStartup08' and many such errors...

我已经从一个教程站点上获取了代码，因此想知道我在做什么错以及应该如何运行该程序.

I have taken the code from a tutorial site and thus would like to know what am i dng wrong and how should i run the program.

非常感谢..

我也曾尝试使用winsock2而不是winsock.h，但错误仍然存​​在...

I have also tried to use winsock2 instead of winsock.h but the errors persist...

推荐答案

-lws2_32 应该这样做.

但是，Cygwin在winsock之上有自己的POSIX兼容套接字实现，通常将它们混在一起不是一个好主意.如果您想坚持使用Winsock，则可能要使用gcc-3的 -mno-cygwin 选项，该选项可以使Cygwin DLL脱颖而出.(您还需要从 #include 行中删除 w32api/.)

However, Cygwin has its own POSIX-compatible socket implementation on top of winsock, and mixing things up generally is not a good idea. If you want to stick with winsock, you probably want to use gcc-3's -mno-cygwin option that takes the Cygwin DLL out of the equation. (You'll also need to drop w32api/ from the #include lines.)
