libubox

lbubox是openwrt的一個核心庫，封裝了一系列基礎實用功能，主要提供事件循環，二進制格式處理，linux鏈表實現和一些JSON輔助處理。

它的目的是以動態鏈接庫方式來提供可重用的通用功能，給其他模塊提供便利和避免再造輪子。

libubox主要提供三部分功能：

1）提供多種基礎通用功能接口，包含鏈表，平衡二叉樹，二進制處理，key-value鏈表，MD5等。

2）socket通信。

3）一套基于事件驅動的機制及任務隊列管理功能。

編譯安裝到PC

1.?修改目錄下CMakelists.txt，先去掉lua部分（不使用lua）。

#OPTION(BUILD_LUA "build Lua plugin" ON)
#ADD_SUBDIRECTORY(lua)

2. cmake編譯安裝

mkdir build; cd build ; cmake .. ; make; make install
