openwrt使用源码编译应用程序

1.跟使用SDK类似，在openwrt/pakage目录下建立如下，具体文件内容见上篇 openwrt使用sdk编译应用程序

song@song-virtual-machine:attitude_adjustment$ ls package/helloworld/
Makefile  src
song@song-virtual-machine:attitude_adjustment$ ls package/helloworld/src/
helloworld.c  Makefile

2.先配置，选中刚添加的helloworld
song@song-virtual-machine:attitude_adjustment$ make menuconfig

Utilities  ---> < *> helloworld......................... Helloworld -- prints a snarky message (NEW)  

3.编译
song@song-virtual-machine:attitude_adjustment$ make V=s

4.会在attitude_adjustment/bin/ar71xx/package下生成ipk文件

song@song-virtual-machine:attitude_adjustment$ ls bin/ar71xx/packages/helloworld_1_ar71xx.ipk 
bin/ar71xx/packages/helloworld_1_ar71xx.ipk

另外，根据需要选择软件包，要想通过web登陆配置，4个地方要选：Base system-->uci，Libraries-->libuci-lua，LuCI全选，Network-->uhttpd。
