篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了libubox相关的知识,希望对你有一定的参考价值。

lbubox是openwrt的一个核心库,封装了一系列基础实用功能,主要提供事件循环,二进制格式处理,linux链表实现和一些JSON辅助处理。

它的目的是以动态链接库方式来提供可重用的通用功能,给其他模块提供便利和避免再造轮子。

libubox主要提供三部分功能:

1)提供多种基础通用功能接口,包含链表,平衡二叉树,二进制处理,key-value链表,MD5等。

2)socket通信。

3)一套基于事件驱动的机制及任务队列管理功能。

编译安装到PC

1. 修改目录下CMakelists.txt,先去掉lua部分(不使用lua)。

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

2. cmake编译安装

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