DHCP 移植
//----------------------------------------------------
//AUTHOR: lanyang123456
//DATE: 2012-3-19
//----------------------------------------------------
dhcp版本： 3.1.3
ARM 开发板：OK6410
Linux内核2.6.28 或3.0.1
1 下载源码：http://download.csdn.net/detail/lanyang123456/4147066 或者http://gd.tuwien.ac.at/infosys/servers/isc/dhcp/ 或者https://www.isc.org/software/dhcp/
2 解压并编译
tar -zxvf dhcp-3.1.3.tar.gz，然后进入dhcp-3.1.3。目录，运行配置./configure，成功之后生成work.linux-2.2文件夹， 进入work.linux-2.2/client目录，
输入make "CC=/usr/local/arm/4.2.2-eabi/arm-linux-gcc -static"，编译生成dhclient。
其中CC=/usr/local/arm/4.2.2-eabi/arm-linux-gcc 为交叉编译器的路径
3 移植到开发板。
拷贝生成的dhclient到OK6410开发板上，为方便使用，可以放在/usr/bin/下.
拷贝配置文件dhcp-3.1.3/client/dhclient.conf和/dhcp-3.1.3/client/scripts/linux 到开发板的/sbin/目录下，并将后一个文件重命名为dhclient-script，并修改该文件的第一行#! /bin/bash 为#! /bin/sh，保存后，修改权限 chmod +x /sbin/dhclient-script。
运行命令
#dhclient wlan0

针对问题
在/var目录下创建state目录，再在state目录下创建dhcp目录
#mkdir /var/state
#mkdir /var/state/dhcp
再次运行dhclient
#dhclient
