ARM Linux根文件系统制作

1. 准备工作Busybox源码下载免费下载地址在 http://linux.linuxidc.com/用户名与密码都是www.linuxidc.com具体下载目录在 /pub/2011/07/20/Busybox/# cd /home/liao# tar –jxvf busybox-1.13.3.tar.bz2# cd busybox-1.13.32. busybox编译2.1修改MakefileCROSS_COMPILE ？=arm-linux-ARCH ？=arm2.2 配置busybox# make menuconfigBusybox Settings--->Build Options--->[*] Build BusyBox as a static binary（no shared libs）[*] Build with Large File Support（for accessing files>2GB） Installation Options->[]Don’t use /usrApplets links （as soft-links） --->（./_install） BusyBox installation prefix 修改（./_install）为/utu2440/rootfs Busybox Library Tuning --->[*] vi-style line editing commands[*]Fancy shell promptsLinux Module Utilities--->（/lib/modules）Default directory containing modules（modules.dep）Default name of modules.dep[ ] simplified modutils[*] insmod[*] rmmod[*] lsmod[*] modprobe-----options common to multiple modutils[ ] support version 2.2/2.4 Linux kernels[*]Support tainted module checking with new kernels[*]Support for module .aliases file[*] support for modules.symbols fileLinux System Utilities --->[*]Support /etc/mdev.conf[*]Support command execution at device addition/removal# make # make install编译出错：networking/interface.c:818: error: `ARPHRD_INFINIBAND" undeclared here （not in a function）networking/interface.c:818: error: initializer element is not constantnetworking/interface.c:818: error: （near initialization for `ib_hwtype.type"）make[1]: *** [networking/interface.o] 错误 1make: *** [networking] 错误 2解决：在networking/interface.c文件中添加：#define ARPHRD_INFINIBAND 32 /* InfiniBand */编译后，在rootfs目录下会生成目录bin、sbin、usr和文件linuxrc的内容3. 建立根文件目录前面已经生成了bin、sbin等目录，这里建立一些必要的文件目录# mkdir dev etc lib proc sys mnt tmp var home boot root# mkdir usr/lib usr/modules# mkdir etc/init.d etc/sysconfig # mkdir mnt/etc mnt/jffs2 mnt/data mnt/temp# mkdir var/lib var/lock var/run var/tmp # chmod 1777 tmp# chmod 1777 var/tmp # sudo mknod -m 600 dev/console c 5 1# sudo mknod -m 600 dev/null c 1 3这两个设备节点需要root用户建立，具体原因有待研究
