MinGW+CB undefined reference to `inet_ntoa@4'

undefined reference to

hxzon:缺少libwsock32.a 。在 Dev-Cpp\lib 和 mingw\lib 下。

==================
我用DEVCPP4.9.7.8编译一SOCKET程序时出现如下编译连接错误：

这是什么原因引起的？
---------------------------
先找到:菜单 Project->project Options ->中的"Linker Options/Optonal Libs or Obeject files ",
点击右边的"Add Library or Object" --> 在你的..\lib目录中找到:"libwsock32.a",选中,点击"打开"-->返回后再按"ok",
重新编译链接即可.
