背景：

Android自带的iproute2 太老，很多指令格式不支持

直接基于Android源码，替换源码下iproute2 代码编译新版，报错太多，于是改用Android NDK工具编译

环境：

android-ndk-r25c-linux.zip 下载链接：NDK 下载 | Android NDK | Android Developers

iproute2源码：Index of /pub/linux/utils/net/iproute2/

我本地编译的两个版本iproute2-5.17.0 和 iproute2-6.9.0

编译：

执行
./configure生成config.mk

修改生成的config.mk

主要是配置编译器以及移除编译器不支持的配置

5.17.0 config.mk

注意：

需要使用大于等于android28 的clang，否则会报找不到glob，低版本clang可以注释掉代码中glob相关代码，非核心功能，就一个文件有用，注释掉不影响核心功能使用

修改NDK头文件，解决编译报错

还有一个比较坑的是用clang编译报 sysroot/usr/include/arpa/inet.h:43:47: error: unknown type name 'in_addr_t'

但是这个定义是在<bits/in_addr.h> 也被include了，如果在inet.h 再定义，编译又报重复定义

于是使用NDK的sysroot/usr/include/arpa/inet.h 添加如下定义

#ifndef in_addr_t
#warning "in_addr_t is NOT defined"
typedef uint32_t in_addr_t;
#else
#warning "in_addr_t is defined"
#endif

源码修改

编译中遇到的报错

iproute2-6.9.0 修改和5.17.0 大部分相同，还有其他几个文件需要修改，修改方法参考上面patch里的文件即可。
