由于MINI2440提供的系统没有DHCP客户端程序，只能设置静态IP，而校园网用户只有动态分配到IP才能上网，故移植想移植DHCP客户端程序，今天终于通过了。
方法如下：
1.下载dhcp-3.1.3.tar.gz解压后执行./configure生成work.linux.2文件
2.进入work.linux.2目录执行make "CC=/usr/local/arm/4.3.2/bin/arm-linux-gcc -static" 即在client目录下生成所需要的dhclient数据文件。拷贝出来下载到板子的/sbin目录下修改权限。运行即可。如下：
[root@FriendlyARM /sbin]# dhclient eth0

3.注意了，友善提供的内核不支持socket。DHCP必需要支持SOCKET的内核，因此重新编译内核，选择支持SOCKET ，编译后下载到板子即可。
4.另外，还需要将client目录下的dhclient-script 下载到/sbin目录并修改权限，dhclient.conf下载到/etc目录并修改权限。
