关于undefined reference to `WSASocketA@24'问题的解决

关于 Eclipse 开发C++ Socket ，在开发的过程中用WinGW 平台编译，

示例server端：

#include <winsock2.h>
#include <mswsock.h>
#include <iostream>
#include <windows.h>
using namespace std;

#pragma comment(lib, "ws2_32.lib")
#pragma comment(lib, "mswsock.lib")

DWORD IniSOCKDLL()
{
WORD wVersionRequested;
WSADATA wsaData;
int err=0;

wVersionRequested = MAKEWORD( 2, 2 );
err = WSAStartup( wVersionRequested, &wsaData );
return err;
}

int main(int argc, char* argv[])
{
IniSOCKDLL();
SOCKET sc=WSASocket(AF_INET,
SOCK_STREAM,
0,
NULL,
0,
NULL);

SOCKADDR_IN addr;
int len;
addr.sin_family=AF_INET;
addr.sin_addr.s_addr = inet_addr("127.0.0.1");
addr.sin_port = htons(1002);
len=sizeof(addr);

connect(sc, (struct sockaddr *)&addr, len);

char buff[1024];
ZeroMemory(buff,1024);

cout<<"邮包开始发送"<<endl;

/*for(int i=0;i<=100;i++)
{
if(i==0)
{*/
   memcpy(buff,"邮包从南京出发",14);
   send(sc,buff,14,0);
   Sleep(1000);
/*}
else if(i<20)
{*/
   memcpy(buff,"邮包在南京和镇江之间",20);
   send(sc,buff,20,0);
   Sleep(1000);

memcpy(buff,"邮包到达镇江",12);
send(sc,buff,12,0);
Sleep(1000);

memcpy(buff,"邮包在镇江和常州之间",20);
send(sc,buff,20,0);
Sleep(1000);

memcpy(buff,"邮包到达常州",12);
send(sc,buff,12,0);
Sleep(1000);

memcpy(buff,"邮包在常州和无锡之间",20);
send(sc,buff,20,0);
Sleep(1000);

memcpy(buff,"邮包到达无锡",12);
send(sc,buff,12,0);
Sleep(1000);

memcpy(buff,"邮包在无锡和苏州之间",20);
send(sc,buff,20,0);
Sleep(1000);

memcpy(buff,"邮包到达苏州",12);
send(sc,buff,12,0);
Sleep(1000);

memcpy(buff,"邮包在苏州和上海之间",20);
   send(sc,buff,20,0);
   Sleep(1000);
/*}
     else
{*/
         memcpy(buff,"邮包到达上海",12);
   send(sc,buff,12,0);
   Sleep(1000);

/* recv(ss,buff,12,0);
cout<<buff<<endl;*/

closesocket(sc);
return 0;
}

会发现Error] C:\Users\HEIORAY\Documents\C-Free\Projects\PING\pi.c:277: undefined reference to `WSASocketA@24'

程序开始时已经导入winsock之类的库，同时#pragma comment(lib,"ws2_32.lib")，但依旧不行，无法消除错误。后来上网搜了一些方法，说是在工程设置中有个连接，在里面加入winsock32就可以了，试过之后的确解决了一些问题。

但是下面的错误还是没有消除，

[Error] C:\Users\HEIORAY\Documents\C-Free\Projects\PING\pi.c:277: undefined reference to `WSASocketA@24'

最后在连接里面再填入一个ws2_32就可以了。如果大家有类似的错误可以试一下。

问题解决可以进行了
