当拿到一含有大量代码的工程怎么看？！这时一个好的代码分析工具非常有用，网上有很多开源工具，但资料都参差不齐，偶然发现doxygen+ graphviz这两工具非常棒，使用工具直接生成函数调用链图，帮助分析整个项目方法的用法以及功能，然后可以方便的分析代码，生成相应的函数调用图
下面是我安装使用过程记录下来了 ps：安装了好几遍后的一个最简洁版的安装过程
一、软件安装。（环境:win10 64bit）
首先，安装doxygen，可以在官网的download页面下载，下载doxygen最新安装包，安装即可。软件集成了32位和64位安装包。然后，安装graphviz，官网下载地址，下载windows安装包。（我这边环境是windows的，也支持mac 类linux系统的版本）
二、配置doxygen。（graphviz安装好后不需要其他配置操作）
doxygen打开的页面如下图所示，有三个配置选项卡：wizard,expert,run。
1）wizard选项卡。
project)step1中先设置doxygen生成文档的工作空间，step2中设置要生成文档的工程名字，源代码的目录，是否递归处理源代码，还有生成文档存放的位置。
mode)中选择要处理的语言
output)略
Diagrams)勾选Use do tool from the GraphViz package，下面的复选框也全勾上。
2）Expert选项卡。
build)中主要勾选EXTRACE_ALL, EXTRACE_PRIVATE, EXTRACE_STATIC, EXTRACE_LOCAL_CALSSES, EXTRACE_LOCAL_METHODS
Doc)中勾选MUL_LOOK, 设置DOT_PATH即doc.exe的位置，位于graphviz安装路径下的bin目录下。（这里比较关键，我一开始没设置路径，识别不出graphviz的地址，继承关系解析出来了，但是图没画出来）。
3）Run选项卡
可以查看Show configuration的配置。以下是我的配置。

点Run doxygen即可开始解析并生成类之间的关系图。
点Show HTML output进行查看。
可以直接点击类 文件等进去看生成的调用图和属性说明。
