基于FS2410的DHCP移植

一、下载源码
,选中 dhcp-3.1-ESV-R3.tar.gz。

二、配置、编译
(1)解压 tar -zxvf dhcp-3.1-ESV-R3.tar.gz,然后进入./dhcp-3.1-ESV-R3/,
home/dhcp/dhcp-3.1-ESV-R3$
运行配置./configure
home/dhcp/dhcp-3.1-ESV-R3$./configure
之后生成work.linux-2.2文件夹,进入work.linux-2.2/目录
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$
输入make "CC=arm-linux-gnu-gcc -static" (在此静态编译,以免发生命令找不到。当然可以动态编译,只要和你的文件系统用的库一致)
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$make "CC=arm-linux-gnu-gcc -static"
将在dhcp-3.1-ESV-R3/work.linux-2.2/client目录下编译生成dhclient。

三、移植到开发板
(1)拷贝生成的dhclient到FS2410开发板上,为方便使用,可以放在/usr/bin/或/sbin目录下;
dhcp-3.1-ESV-R3/work.linux-2.2/client$cp dhclient /rootfs/filesystem/sbin
拷贝另外两个配置文件到开发板,分别是/dhcp-3.1-ESV-R3/client/dhclient.conf
                                                                       /dhcp-3.1-ESV-R3/client/scripts/linux
到开发板的/sbin/目录下。并改名后一个文件为dhclient-script
home/dhcp/dhcp-3.1-ESV-R3/client$cp dhclient.conf /rootfs/filesystem/sbin
home/dhcp/dhcp-3.1-ESV-R3/client/scripts$cp linux /rootfs/filesystem/sbin/dhclient-script
(2)并修改dhclient-script该文件的第一行#!/bin/bash#!/bin/sh

(3)保存后修改权限 rootfs/filesystem$sudo chmod +x /sbin/dhclient*

四、测试
为eth0 或者wlan0配置dhcp服务,输入dhclient eth0 或者dhclient wlan0 即可,得到如下类似信息:

eth0:
