下载解压busybox

tar xf busybox-1.20.2.tar.bz2

 

设置交叉编译器

enzo@debian:~/work/tq2416/tmp_rootfs/busybox-1.20.2$ arm-linux-gcc -v
Using built-in specs.
Target: arm-none-linux-gnueabi
Configured with: /scratch/maxim/arm-lite/src-4.3-arm-none-linux-gnueabi-lite/gcc-4.3/configure --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --target=arm-none-linux-gnueabi --enable-threads --disable-libmudflap --disable-libssp --disable-libstdcxx-pch --with-gnu-as --with-gnu-ld --with-specs='%{funwind-tables|fno-unwind-tables|mabi=*|ffreestanding|nostdlib:;:-funwind-tables}' --enable-languages=c,c++ --enable-shared --enable-symvers=gnu --enable-__cxa_atexit --with-pkgversion='Sourcery G++ Lite 2009q1-176' --with-bugurl= --disable-nls --prefix=/opt/codesourcery --with-sysroot=/opt/codesourcery/arm-none-linux-gnueabi/libc --with-build-sysroot=/scratch/maxim/arm-lite/install-4.3-arm-none-linux-gnueabi-lite/arm-none-linux-gnueabi/libc --with-gmp=/scratch/maxim/arm-lite/obj-4.3-arm-none-linux-gnueabi-lite/host-libs-2009q1-176-arm-none-linux-gnueabi-i686-pc-linux-gnu/usr --with-mpfr=/scratch/maxim/arm-lite/obj-4.3-arm-none-linux-gnueabi-lite/host-libs-2009q1-176-arm-none-linux-gnueabi-i686-pc-linux-gnu/usr --disable-libgomp --enable-poison-system-directories --with-build-time-tools=/scratch/maxim/arm-lite/install-4.3-arm-none-linux-gnueabi-lite/arm-none-linux-gnueabi/bin --with-build-time-tools=/scratch/maxim/arm-lite/install-4.3-arm-none-linux-gnueabi-lite/arm-none-linux-gnueabi/bin

修改Makefile 交叉编译器

164行  CROSS_COMPILE ?= arm-linux-

 

配置busybox

选上以下几项:
Busybox Settings --->
         Build Options --->
               [*] Build BusyBox as a static binary (no shared libs)
               [*] Build with Large File Support (for accessing files > 2 GB)
         Busybox Library Tuning --->
               [*] vi-style line editing commands
               [*] Fancy shell prompts
Linux Module Utilities --->
        [ ] Simplified modutils
        [*] insmod
        [*] rmmod
        [*] lsmod
        [*] modprobe
        [*] depmod


编译

make

make install

在busybox目录下产生_install子目录,这就是刚编译好busybox生成文件目录

改名

mv _install rootfs_2416

 

创建脚本自动生成一些默认目录和文件

#!/bin/sh
#root dir
mkdir bin sbin lib etc dev sys proc tmp var opt mnt usr home root media
#usr sub dir
cd usr
mkdir bin sbin lib local
#usr/local sub dir
cd local
mkdir bin sbin lib
cd ../..
#etc sub dir
cd etc
touch inittab
touch fstab
touch profile
touch passwd
touch group
touch shadow
touch resolv.conf
touch mdev.conf
touch inetd.conf
mkdir rc.d
mkdir init.d
mkdir udev
touch init.d/rcS
chmod +x init.d/rcS
mkdir sysconfig

touch sysconfig/HOSTNAME
cd ..
#dev sub dir
cd dev
sudo mknod console c 5 1
sudo chmod 777 console
sudo mknod null c 1 3
sudo chmod 777 null
