linux下使用doxygen和grapviz生成函数调用关系图

本文主要是介绍linux下使用doxygen和grapviz生成函数调用关系图，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1，参考链接

https://jasoncc.github.io/doc_tools/doxygen.html

2，操作流程

以ubuntu为例，执行如下命令来生成doxygen

$ sudo apt-get install doxygen
$ sudo apt-get install graphviz
$ mkdir /tmp/doxygen && cd /tmp/doxygen
$ doxygen -g my.doxygen
$ vim my.doxygen
$ doxygen mydoxygen

其中，编辑my.doxygen如下，INPUT设置你的源码目录

# document all entities in the project.
EXTRACT_ALL            = YES# document all static members of a file.
EXTRACT_STATIC         = YES# specify the root directory that contains the project's source files.
INPUT                  = /home/test/source# search sub-directories for all source files.
RECURSIVE              = YES# include the body of functions and classes in the documentation.
INLINE_SOURCES         = YES# generate visualization graph by using dot program (part of graphviz package).
HAVE_DOT               = YES# generate a call dependency graph for every global function or class method.
CALL_GRAPH             = YES
