build busybox for imx51

1. 官網下載
version 1.17.3

2. 解壓縮
tar jxvf busybox-1.17.3.tar.bz2.tar

3. 設定環境變數

export CROSS_COMPILE=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-

cross compile工具跟你系統會有關係

所以通常需要修改此部份

FAQ網頁有說明如果要使用cross_compile要設定CROSS_COMPILE參數

4. build busybox

make defconfig

/*

To enable all features, use "make defconfig", which produces the largest

general-purpose configuration.

*/

make menuconfig

  # select Busybox Settings

  #   then General Configuration

  #     then exec prefers applets

  #   exit back to top level menu

  #   select Shells

  #     then Standalone shell

  #   exit back to top level menu

  # exit and save new configuration

make

檢查一下busybox檔案屬性

file busybox

busybox: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), stripped

如果想要build出static

此篇文章有教學

再看一次

nelsonchung@gps1004:~/busybox-1.17.3$ file busybox

busybox: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.14, stripped
