busybox移植

1、首先下载busybox源码。官网地址https://busybox.net/。

2、在linux系统中解压源码包。tar -jxvf busybox-1.24.1.tar.bz2

3、修改Makefile，添加两行：

ARCH = arm

CROSS_COMPILE = arm-linux-

4、编译busybox。直接make menucnofig

(1)配置busybox为静态库链接

Busybox Settings--->
Build Options--->
[*]Build BusyBox as a static binary(no shared libs)

（2）配置busybox vi风格

Busybox Library Tuning--->
[*]vi-style line editing commands
[*]Fancy shell prompts

（3）Linux Module Utilities--->
[ ]Simplified modutils
[*]insmod
[*]rmmod
[*]lsmod
[*]modprobe
[*]depmod

（4）Linux System Utilities--->
[*]mdev
[*]Support /etc/mdev.conf
[*]Support subdirs/symlinks
[*]Support regular expressions substitutions when renaming dev
[*]Support command execution at device addition/removal
[*]Support loading of firmwares

然后make -j4快速编译。编译会出错，sync.c:(.text.sync_main+0x90): undefined reference to `syncfs'一般是当前的编译器的问题。现在选择跳过该文件编译，修改make menuconfig.

Coreutils  --->
[ ] sync

编译出错：nsenter.c:(.text.nsenter_main+0x1a4): undefined reference to `setns'

make menuconfig

Linux System Utilities--->

[ ] nsenter，去掉该选项，重新编译make

 

再次编译可通过。生成busybox文件代表编译完成

5、编译通过之后安装。可以修改安装目录

6、待增加
