busybox(二)编译

1. 解压,源码包在busybox-1.7.0.tar.bz2,

   tar xjf  busybox-1.7.0.tar.bz2
   cd busybox-1.7.0/

2. 查看说明文档INSTALL,注意不能直接使用make install,这样会安装到pc上,破坏pc.应该要使用make CONFIG_PREFIX=xxx目录 install

    make menuconfig     # This creates a file called ".config"
    make                # This creates the "busybox" executable  
    make install        # or make CONFIG_PREFIX=/path/from/root install

3. 设置下交叉编译工具为arm-linux-,修改顶层Makefile

   CROSS_COMPILE   ?=arm-linux-

4. 使用make menuconfig配置,发现提示错误,这是因为版本问题,修改下makefile

   [email protected]:/work/busybox-1.7.0$ make menuconfig
   Makefile:405: *** mixed implicit and normal rules: deprecated syntax
   Makefile:1242: *** mixed implicit and normal rules: deprecated syntax
   make: *** No rule to make target ‘menuconfig‘.  Stop.

   修改以下内容

   顶层Makefile 405行:config %config: scripts_basic outputmakefile FORCE 改为:
   %config: scripts_basic outputmakefile FORCE
   
   修改busybox-1.7.0 顶层Makefile 1242行:
   / %/: prepare scripts FORCE   改为:
   %/: prepare scripts FORCE
   
   如果还不行 
   要安装 sudo apt-get install libncurses5-dev libncursesw5-dev 这两个库才可以

5. 修改配置项目,增加tab补全功能,busybox settings ---busybox libry tuning ----tab completion,输入y选择.其余模块的使能一般在Linux Module Utilities --->中

6. make

7. 设置安装路径make CONFIG_PREFIX=~/stu/first_fs install

8. 可以看到文件链接到busybox,也就是说bin下面有个busybox的程序,其他ls等都链接到它

   [email protected]:~/stu/first_fs$ ls -l
   总用量 12
   drwxrwxr-x 2 book book 4096 11月 13 23:37 bin
   lrwxrwxrwx 1 book book   11 11月 13 23:37 linuxrc -> bin/busybox
   drwxrwxr-x 2 book book 4096 11月 13 23:37 sbin
   drwxrwxr-x 4 book book 4096 11月 13 23:37 usr
   
   
   [email protected]:~/stu/first_fs$ ls bin/ls -l
   lrwxrwxrwx 1 book book 7 11月 13 23:37 bin/ls -> busybox
