[tekkamanninja@Tekkaman-Ninja busybox-1.9.1]$ make
......
LINK busybox_unstripped
Trying libraries: crypt m
Library crypt is needed
Library m is needed
Final link with: crypt m
[tekkamanninja@Tekkaman-Ninja busybox-1.9.1]$ make install
我是动态编译所以查看一下需要的动态库
[tekkamanninja@Tekkaman-Ninja busybox-1.9.1]$ /home/tekkamanninja/working/gcc4.1.1/gcc-4.1.1-glibc-2.3.2/arm-9tdmi-linux-gnu/bin/arm-9tdmi-linux-gnu-readelf -d busybox
Dynamic section at offset 0xac014 contains 22 entries:
Tag Type Name/Value

（3）修改和创建必要的文档。
[tekkamanninja@Tekkaman-Ninja busybox-1.9.1]$ cp -a examples/bootfloppy/etc/* /home/tekkamanninja/working/nfs/rootfs/etc/
[tekkamanninja@Tekkaman-Ninja busybox-1.9.1]$ cd ../../nfs/rootfs/etc/
1、增加为SHELL导入全局变量的文档/etc/profile
[tekkamanninja@Tekkaman-Ninja etc]$ kwrite profile
# /etc/profile: system-wide .profile file for the Bourne shells
echo
echo "Processing /etc/profile... "
# no-op
# Set search library path
echo "Set search library path in /etc/profile"
export LD_LIBRARY_PATH=/lib:/usr/lib
# Set user path
echo "Set user path in /etc/profile"
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
# Set PS1
#注意：ash 除了SHELL变量外，支持\u、\h、\W、\$、\!、\n、\w 、\nnn（ASCII字符对应的八进制数）
#连同\e[xx;xxm (彩色特效)等等！
#而且前面还要多加一个 '\'！
echo "Set PS1 in /etc/profile"
export PS1="\\e[05;32m[$USER@\\w\\a]\\$\\e[00;34m"
echo "Done"
echo
2、增加初始化文档
[tekkamanninja@Tekkaman-Ninja etc]$ kwrite inittab
::sysinit:/etc/init.d/rcS
::respawn:-/bin/login
::restart:/sbin/init
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
::shutdown:/sbin/swapoff -a
[tekkamanninja@Tekkaman-Ninja etc]$ kwrite fstab
proc /proc proc defaults 0 0
none /tmp ramfs defaults 0 0
mdev /dev ramfs defaults 0 0
sysfs /sys sysfs defaults 0 0
3、增加初始化脚本
[tekkamanninja@Tekkaman-Ninja etc]$ kwrite init.d/rcS
#! /bin/sh
echo "----------mount all"
/bin/mount -a
echo "----------Starting mdev......"
/bin/echo /sbin/mdev > /proc/sys/kernel/hotplug
mdev -s
echo "*********************************************************"
echo " Tekkaman Ninja 2440 Rootfs(nfs) 2008.2 "
echo " Love Linux ! ! @@ Love Ke Ke ! ! "
echo "********************************************************"
4、删除备份文档
[tekkamanninja@Tekkaman-Ninja etc]$ rm *~ init.d/*~
5、为mdev创建配置文档
[tekkamanninja@Tekkaman-Ninja etc]$ vi mdev.conf
创建一个mdev.conf文档，内容可有可无。
（4）为使用用户登录功能移植TinyLogin
1、下载
从http://tinylogin.busybox.net/ 下载tinylogin-snapshot.tar.bz2，并解压.
[tekkamanninja@Tekkaman-Ninja source]$ tar -xjvf tinylogin-snapshot.tar.bz2
2、修改tinyLogin的Makefile
[tekkamanninja@Tekkaman-Ninja source]$ cd tinylogin
[tekkamanninja@Tekkaman-Ninja tinylogin]$ kwrite Makefile
指明tinyLogin使用自己的算法来处理用户密码
