研发客服arm-linux-gcc 3.4.5
busybox-1.24.1.tar.bz2
1, 修改 Makefile
找到以下2处修改为
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-
2, 打开配置菜单
make menuconfig
这里进行一些配置，打开 TAB 补全功能，选中 ifconfig , 打开驱动加载功能等
可以按 / 后输入字符进行搜索

make menuconfig 去掉 nandwrite，nanddump模块
错误4
miscutils/ubi_tools.c:67:26: mtd/ubi-user.h: No such file or directory
miscutils/ubi_tools.c: In function `ubi_tools_main':
miscutils/ubi_tools.c:106: error: `UBI_DEV_NUM_AUTO' undeclared (first use in this function)

错误5
util-linux/umount.c: In function `umount_main':
util-linux/umount.c:87: error: `MNT_DETACH' undeclared (first use in this function)
util-linux/umount.c:87: error: (Each undeclared identifier is reported only once
util-linux/umount.c:87: error: for each function it appears in.)
make[1]: *** [util-linux/umount.o] Error 1
make: *** [util-linux] Error 2
方法：
umount 这里不能去掉了，因为这个功能是需要的 打开源码看看
83 // MNT_FORCE and MNT_DETACH (from linux/fs.h) must match
84 // OPT_FORCE and OPT_LAZY.
85 {
86 typedef char bug[
87 (OPT_FORCE != MNT_FORCE || OPT_LAZY != MNT_DETACH) ? -1 : 1
88 ];
打开 ARM GCC 的 include/linux/fs.h 确实没有发现这2个定义
从 linux 内核源码里面找到这个 include/linux/fs.h
找到里面的这个
#define MNT_FORCE 0x00000001 /* Attempt to forcibily umount */
#define MNT_DETACH 0x00000002 /* Just detach from the tree */
把这里直接写为2 在次 make
错误6
coreutils/lib.a(sync.o)(.text.sync_main+0x80): In function `sync_main':
: undefined reference to `syncfs'
collect2: ld returned 1 exit status
make: *** [busybox_unstripped] Error 1
解决：
vi ./coreutils/sync.c
/*
* syncfs is documented to only fail with EBADF,
* which can't happen here. So, no error checks.
*/
86行 syncfs(fd);
18 行 //config: bool "Enable -d and -f flags (requres syncfs(2) in libc)"
找了一个 arm-libc 中并没有这个函数
下载了 busybox-1.23.0.tar.bz2 找到同名文件，发现这个内容明显要简单很多。用 1.23 的版本替换 1.24 的。
#include "libbb.h"
/* This is a NOFORK applet. Be very careful! */
int sync_main(int argc, char **argv) MAIN_EXTERNALLY_VISIBLE;
int sync_main(int argc UNUSED_PARAM, char **argv IF_NOT_DESKTOP(UNUSED_PARAM))
{
/* coreutils-6.9 compat */
bb_warn_ignoring_args(argv[1]);
sync();
return EXIT_SUCCESS;
}
在次编译通过了
Your linker does not support --sort-section,alignment
Trying libraries: crypt m
Library crypt is not needed, excluding it
Library m is needed, can't exclude it (yet)
Final link with: m
安装
make CONFIG_PREFIX=/opt/fs_1.24 install
制作 /dev/ 设备节点
cd /opt/fs_1.24
mkdir dev
cd dev
mknod console c 5 1
mknod null c 1 3
创建 etc 和 启动目录
cd ..
mkdir etc/init.d -p
创建启动脚本
vi etc/inittab
console::askfirst:-/bin/sh
::sysinit:/etc/init.d/rcS
编辑启动脚本启动 fstab 挂载设备节点等
vi etc/init.d/rcS
#!/bin/sh
mount -a
mkdir /dev/pts
mount -t devpts devpts /dev/pts
echo /sbin/mdev > /proc/sys/kernel/hotplug
mdev -s
创建自动挂载文件
mkdir tmp
mkdir sys
mkdir proc
vi etc/fstab
#device mount-point type optionos dump fsck order
proc /proc proc defaults 0 0
tmpfs /tmp tmpfs defaults 0 0
sysfs /sys sysfs defaults 0 0
tmpfs /dev tmpfs defaults 0 0
复制 C 库
mkdir lib
cd /opt/gcc/arm-linux/lib
cp *.so* /opt/fs_1.24/lib/ -d
制作好了， 用 NFS 启动吧。

配置成功。
rmmod 时出现错误 , 按提示创建 目录即可。
rmmod: can't change directory to '/lib/modules': No such file or directory
mkdir /lib/modules
rmmod: can't change directory to '2.6.22.6': No such file or directory
mkdir /lib/modules/2.6.22.6
ps: gcc-4.3.2 编译时错误少很多。
