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
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
