openwrt SDK, 利用SDK生成自己的ipk安装包
Openwrt SDK是一个可再定位的，预编译好的OpenWrt工具链，适用于在不从头开始编译整个系统的前提下，针对一个特定平台交叉编译单个用户空间包。
使用SDK的原因：
为了保证二进制和特性兼容性，针对特定的发行版编译自定义软件
编译更新版本的指定包文件
使用自定义的补丁或者不同特性来重新编译已经存在的包
#-----官方文档如下
This is the OpenWrt SDK. It contains a stripped-down version of the buildroot. You can use it to test/develop packages without having to compile your own toolchain or any of the libraries included with OpenWrt.
To use it, just put your buildroot-compatible package directory in the subdir 'package/' and run 'make' from this directory.

具体操作如下:
利用 SDK 生成自己的ipk安装包,
下载 http://pan.baidu.com/share/link?shareid=123840&uk=1577556057
1. 解压
tar jxvf OpenWrt-SDK-ar71xx-for-linux-i486-gcc-4.6-linaro_uClibc-0.9.33.2.tar.bz2
2. 进入目录
cd OpenWrt-SDK-ar71xx-for-linux-i486-gcc-4.6-linaro_uClibc-0.9.33.2
3. 将自己的代码目录拷贝到本目录的 package目录下
注意 Makefile 必须遵守openwrt的规则, 可参考
http://blog.chinaunix.net/uid-27194309-id-3432651.html
4. 编译, 成功后在bin/ar71xx/packages目录下可以看到相关的ipk文件, 可用winscp 拷贝出来
#编译所有组件
make V=99
#单独编译某个组件
make package/hid/compile
5. 安装到路由器上实验, 这个你们都懂的
#注: SDK的目录不要改动, 否则出现如下错误
