都是我的错,请您告诉我---为什么Busybox编译有问题???

我的编译步骤如下:
1.make menuconfig

General Configuration
    Buffer allocation policy (Allocate on the Stack)  --->           

Show verbose applet usage messages                              

• Use the devpts filesystem for Unix98 PTYs                        
  
• Support for SUID/SGID handling                                   
  
•    Runtime SUID/SGID configuration via /etc/busybox.conf         
  
•      Suppress warning message if /etc/busybox.conf is not readable
  
  Build Options
  
• Build BusyBox as a static binary (no shared libs)         
  
• Do you want to build BusyBox with a Cross Compiler?      
  (/usr/local/arm/2.95.3/bin/arm-linux-) Cross Compiler prefix  
  ()  Any extra CFLAGS options for the compiler?               
  
  Installation Options
     
• Don't use /usr                  
  (./_install) BusyBox installation prefix
  
  2. make
  /usr/local/arm/2.95.3/bin/arm-linux-gcc -I/media/NO_NAME/busybox/include -I/medi a/NO_NAME/busybox/include -I/media/NO_NAME/busybox/libbb -Wall -Wstrict-prototyp es -Wshadow -Os -fstrict-aliasing -fomit-frame-pointer -D_GNU_SOURCE -DNDEBUG   -c -o /media/NO_NAME/busybox/networking/route.o /media/NO_NAME/busybox/network ing/route.c

  make: *** [/media/NO_NAME/busybox/networking/route.o] 错误 1　　　　　　

我也遇到这个编译route时发生的错误。我现在没有打开route，不知道高手们怎么解决的。　　　　　　

我也是相似的问题，是不是交叉编译环境没有设置好？请教楼上的两位在make menuconfig时build option 中Do you want to build BusyBox with a Cross Compiler那一项是怎么填写的？特别是后缀怎么写？　　　　　　

确定交叉编译器编译完成了？　　　　　　

觉得uclinux编译时不太稳定,第一次用make menuconfig时编译正确,第二次用make xconfig配置过后不能编译,再次用make xconfig时,配置图形界面出不来,用make menuconfig可以配置,但编译又出错了.　　　　　　

可能是编译器的问题，强烈建议在redhat 7.1或7.3下编译。　　　　　　

你的busybox什么版本？　　　　　　

我现在也在尝试编译busybox，遇到了几乎相同的问题,我的环境是FC6+CROSS 2.95.3+busubox-1.00。。
不知大家当初是如何解决这一问题的？换用3.3.2编译就可以了吗？由于我之前已经用2.95.3编译了qte，qtopia，如果在换3.3.2编译感觉有点麻烦呢，大家能给些建议吗？谢谢啦　　　　　　

你可以看看busybox中的readme 后install文档它已经说的很明白了这是我编译时的环境和步骤redhat9.0, 先#redhat-config-packages进入软件包管理把开发工具包全部打上.
1先到http://www.busybox.net下载busybox.tar.gz软件
2:以root权限#tar -zxvf busybox-1.0.tar.gz解压
3:#cd busybox-1.0
4:#make menuconfig进入菜单界面把 1:general configuration(*),show verbose applet usagemessage(*),runtime suid/sgid configuration via/etc/busybox.conf(*)2:build option build busybox as staic binary采用静态编译不要用到动态链接库.3install option don`t /usr一定要选,其他一些命令你自己选.然后esc键出来它询问你是否要保存你就yes然后
5#make
6#make install或make PERFIX=你要装的目录举个例子/tmp目录#make PERFIX=/tmp install.
7编译好之后你到busybox-1.0中可以看见一个_install的目录那就是你编译的文件有/sbin /bin linuxrc
用命令#ls -l 看一下可以发现linuxrc -> /bin/busybox其实是一软链接.1.0版本默认自动可以给你创建但别的高的版本有一个选项要你选择init,其实/sbin /bin里面的都是链接busybox的软链接,你可以到_install目录下#./busybox你就会看见你自己编译进去的命令有多少, 举个例子如果我把_instal目录里的 ls删去也没多大的关系因为它是指向busybox的链接你可以自己创建#ln -s busybox ls就可以创建ls->busybox其实也可以#./busybox ls相当用了ls命令前提你要把ls命令编译进去.
7_install目录下有一个有个init.d的目录里面有个rcS的脚本
mount -a表示一起动挂载fstab中所有的文件.你可以在里面写
#! /bin/sh
PATH=/bin:/sbin
export PATH
mount -a
ifconfig eth0 192.168.18.22 up这是以模块加载用的,如果你直接把网卡编译到内核你可以ifconfig eth0 192.16.22
modprobe 你开机需要加载的模块名比方8139too 是8139网卡模块2.4内核是8139too.o,2.6内核是8139too.ko
modprobe 8139too自动加载模块主要依靠/lib/modules/module.dep文件
8:inittab和系统的不太一样其实很简单它么有什么runlevel
内容如下:
::sysinit:/etc/init.d/rcS
::respawn:-/bin/sh
::ctrlaltdel:/sbin/reboot
基本上完成了busybox编译你可以在建根目录下其他的文件 /sbin ,/ bin, busybox目录_install目录有了,v目录拷贝系统/dev目录中的设备结点用以下是一定要的 mem(物理内存存取) null为黑洞什么数据进去都化为无形.zero以null byte零值字节为数据来源.random为真随机书产生器,tty0为现行的虚拟控制台,tty1为第一个虚拟控制台,ttyS0为第一个uart串行端口,tty为现行的tty设备.console为系统控制台.还有如果你用的是ide的硬盘就拷贝hda1,2,3.....如果是SATA你就考sda1,2,3.....
以上用命令考#cp -R /dev/mem /你的u盘要不cf.dom盘里其余一样做.
根目录至少有/etc, /dev , /bin, /sbin /proc /root 不过你如果要启动加载模块最好把/lib目录建上还有要在小系统上运行某个程序最好用ldd查看链接库拷贝到/lib相应的目录.
/proc目录为空主要管理内核它主要是内存的映射
/dev为以上的那些设备
/sbin和/bin在_install目录拷出来就行
/root为空
/etc文件有init.d目录, fstab目录可以参考系统本身的fstab
其实也可以参考_install目录的的例子文件夹里的floppy 文件夹里的文件复制到你的/etc目录就行
根目录好了就开始编译内核,我也不多说了.其实也可以到系统/boot目录里用系统的vmlinuz-2.x.y和initrd.img文件
