嵌入式系统根文件系统制作 一、主机环境?Linux vm-dev 2.6.9-42.EL RedHatEL4, VMWare6.0.3;?gcc version 3.4.6(Red Hat 3.4.6-3) Thread model: posixgcc version 3.4.6?所需源文件：?busybox-1.12.2.tar.bz2; 二、用Busybox创建文件系统?busybox-1.12.2.tar.bz2拷贝到了虚拟机的/home/uptech目录 1、解压busybox-1.12.2.tar.bz2，路径为[root@vm-dev ~]cd /home [root@vm-dev home]mkdir hq [root@vm-dev home]# cd hq [root@vm-dev hq]#mkdir rootfs [root@vm-dev hq]# cd rootfs [root@vm-dev rootfs]#cp /home/uptech/busybox-1.12.0.tar.bz2 . -arf [root@vm-dev rootfs]# ls busybox-1.12.0.tar.bz2 [root@vm-dev rootfs]# tar -vxjf busybox-1.12.2.tar.bz2 [root@vm-dev rootfs]# cd busybox-1.12.2 [root@vm-dev busybox-1.12.2]# pwd /home/hq/rootfs/busybox-1.12.2 [root@vm-dev busybox-1.12.2]# vi Makefile [root@vm-dev busybox-1.12.2]# 修改Makefile中的ARCH和CROSS_COMPILE与本机的路径一致：CROSS_COMPILE ?= arm-linux- ...ARCH ?= arm 2、编译busybox。先make menuconfig，修改以下： [root@vm-dev busybox-1.12.2]# make menuconfig Busybox Settings ????Build Options ????????[*] Build BusyBox as a static binary (no shared libs)????????//直接编译成静态库，省事点????????(/opt/crosstools/gcc-3.4.6-glibc-2.3.6/bin/arm-linux-) Cross Compiler prefix????????//这里和Makefile里保持一致，应该写一处就行了????Installation Options ????????[ ] Dont use /usr????????//使用usr目录Busybox Library Tuning [*] Fancy shell prompts //一定要选上，否则很多转意字符无法识别Shells ????Choose your default shell (ash) ????//这里选择shell为ash，应该是默认选中的???????? ash????????//把ash这档的选项全部选上Miscellaneous Utilities [ ] inotifyd //不选 Linux Module Utilities [ ] Simplified modutils// 不选 [ ] depmod [*] insmod [ ] Module version checking (NEW) [ ] Add module symbols to kernel symbol table (NEW) [ ] In kernel memory optimization (uClinux only) (NEW) [ ] Enable load map (-m) option (NEW) [*] rmmod [*] lsmod 保存退出，直接make，make install。[root@vm-dev busybox-1.12.2]# ls _install/ bin linuxrc sbin usr [root@vm-dev busybox-1.12.2]# 3、用shell脚本创建根文件系统的目录结构，并在想要建立根文件
