1. busybox

出场白：

BusyBox 是一个集成了三百多个最常用Linux命令和工具的软件。BusyBox 包含了一些简单的工具，例如ls、cat和echo等等，还包含了一些更大、更复杂的工具，例grep、find、mount以及telnet。有些人将 BusyBox 称为 Linux 工具里的瑞士军刀。简单的说BusyBox就好像是个大工具箱，它集成压缩了 Linux 的许多工具和命令，也包含了 Linux 系统的自带的shell。

2. 下载

busybox - BusyBox: The Swiss Army Knife of Embedded Linux

2. 解压，配置

tar xjvf  busybox-1_30_0.tar.bz2

cd busybox-1_30_0

因为我的是交叉编译到arm上运行， 需要修改Makefile:

 

执行meke menuconfig, 设置静态编译

 

4. 编译

执行make -j6

报错：

再次执行make menucofig, 去除掉nsenter 和sync 命令

# 去除nsenter

#去除sync

 

保存修改，再次编译：make -j6

成功：

book@book-virtual-machine:/work/busybox/busybox-1_30_0$ ls -l busybox
-rwxrwxr-x 1 book book 1990416 Oct  5 18:58 busybox
book@book-virtual-machine:/work/busybox/busybox-1_30_0$
 

5. 安装

执行make install

在busybox-1_30_0/_install 目录下安装成功：

book@book-virtual-machine:/work/busybox/busybox-1_30_0/_install$ ls -l
