结果还是一样的~~咋回事呢？谢谢大家帮帮忙

屏蔽掉busybox中的iptunnel选项，然后重新编译即可。

那个IPtunnel 不编译就行了

struct iphdr有两个地方有定义
一个是/opt/EmbedSky/4.3.3/bin/../arm-none-linux-gnueabi/libc/usr/include/linux/ip.h
一个是/opt/EmbedSky/4.3.3/bin/../arm-none-linux-gnueabi/libc/usr/include/linux/netinet
将ip.h中的iphdr名字改掉也可以编译通过

呵呵，终于有人找到了最终的解答了。
错误提示信息：

这句话讲了：In file included from /opt/EmbedSky/4.3.3/bin/../arm-none-linux-gnueabi/libc/usr/include/linux/if_tunnel.h:5,在头文件if_tunnel.h第五行调用了ip.h这个头文件；
下面这句话：
/opt/EmbedSky/4.3.3/bin/../arm-none-linux-gnueabi/libc/usr/include/linux/ip.h:85: error: redefinition of 'struct iphdr'在头文件ip.h的85行又redefinition（翻译成中文是：重复定义）了结构体 iphdr。
iphdr结构在另外一个头文件中定义了：arm-none-linux-gnueabi/libc/usr/include/netinet/ip.h的45行。而这个头文件正好现在iptunnel.c文件的17行调用了。linux/if_tunnel.h头文件在24行调用的。

最合理的解决方法：修改busybox的源码：把busybox-1.13.0\networking\libiproute\iptunnel.c文件的24行屏蔽掉就行了。

/*#include <linux/if_tunnel.h>*/把这行屏蔽就又出现新的错误了

楼上这样好像不行哦！！！

还是把networking utilites     ->ip tunnel 屏蔽

ip tunnel

大家好，networking utilites     ->ip tunnel 屏蔽不了阿
我按 了“N”屏幕闪以下 ，但没有屏蔽阿
怎么操作才可以 屏蔽呢？

利用空格键来选择或者取消

楼上正解

10# kp03

找到ip tunnel项，用空格选择，将

变成[ ]，然后退出保存，记得保存！

用空格键也不能取消ip tunnel项，请问下这该怎么办啊？

我最近才知道那是什么原因，是那个系统的gcc编译器出现问题，我用ubuntu的系统换成了redhat系统在安装下gcc就好了。这个问题可让我足足头痛了好久。
