Busybox 裁剪[Z]

转自：http://blogold.chinaunix.net/u2/75705/showart_1286345.html

 

 

   因为原先板子上的busybox大小接近2MB,包含的东西太多,现在又需要把系统裁到 16 MB了,

并且原来是static编译的, 并且/lib中存在uclibc库, 应用程序也需要使用, 浪费了。

    所以决定重新对busybox进行裁剪，编译为动态链接库，初步估计能省下1.5 MB的宝贵空间。

 

步骤:

1. 解压

2. 修改Makefile 的 CROSS_COMPILE

3. 根据产品需求配置

 make menuconfig

 生成的.config文件如下:

5. 生成文件及分析：

[tudouren@host busybox-1.12.1]$ my-linux-readelf -a _install/bin/busybox | grep "Shared"
 0x00000001 (NEEDED)                     Shared library: [libc.so.0]

 

[tudouren@host busybox-1.12.1]$ du -h _install/bin/busybox
516K    _install/bin/busybox

 

基本达到目标了, 再经过flash文件系统压缩应该只有200k左右。
