获取本机地址信息，遇到小问题...有待解决

程序代码：

1 #include "../common/InitSock.h"
2 #include <stdio.h>
3 CInitSock initSock;
4 void main()
5 {
6     char szHost[256];
7     ::gethostname(szHost,256);
8     hostent *pHost = ::gethostbyname(szHost);
9     in_addr addr;
10     for(int i =0;;i++)
11     {
12         char *p = pHost->h_addr_list[i];
13         if(p == NULL)
14             break;
15         memcpy(&addr.S_un.S_addr, p, pHost->h_length);
16         char *szIp = ::inet_ntoa(addr);
17         printf("本地IP地址：%s \n",szIp);
18     }
19 }

第一次编译说 找不到 ../common/InitSock.h

然后百度说，自己弄个头文件就行：

1 #include  <winsock2.h>
2 #pragma comment(lib, "WS2_32 ")
3 #pragma comment(lib, "ws2.lib ")    //   链接到WS2_32.lib
4 class   CInitSock
5 {
6     public:
7     CInitSock(BYTE   minorVer   =   2,   BYTE   majorVer   =   2)
8     {
9         //   初始化WS2_32.dll
10         WSADATA   wsaData;
11         WORD   sockVersion   =   MAKEWORD(minorVer,   majorVer);
12         if(::WSAStartup(sockVersion,   &wsaData)   !=   0)
13         {
14             exit(0);
15         }
16     }
17
18     ~CInitSock()
19     {
20         ::WSACleanup();
21     }
22 };

然后保存成：initsock.h 但这个方法不好使：

然后继续编译，说是缺少win32.lib...很是奇怪
