Doxygen 生成UML类图

1）安装graphviz

yum install graphviz

 2) 安装doxygen

Doxygen: Downloads

git clone https://github.com/doxygen/doxygen.git
cd doxygen

After that you can use

mkdir build
cd build
cmake -G "Unix Makefiles" ..
make

To force a fresh build after an earlier check-out simple remove the build directory and redo the steps above.

After the binaries have been built, you can use

make install

to install them. 

3) 在需要产生类图的目录下执行

doxygen -g

此命令会在当前目录产生配置文件 Doxyfile， 编辑此文件，与UML相关的几个配置项：

# If the UML_LOOK tag is set to YES, doxygen will generate inheritance and
# collaboration diagrams in a style similar to the OMG's Unified Modeling
# Language.
# The default value is: NO.
# This tag requires that the tag HAVE_DOT is set to YES.

UML_LOOK               = YES

# If the UML_LOOK tag is enabled, the fields and methods are shown inside the
# class node. If there are many fields or methods and many nodes the graph may
# become too big to be useful. The UML_LIMIT_NUM_FIELDS threshold limits the
# number of items for each type to make the size more manageable. Set this to 0
# for no limit. Note that the threshold may be exceeded by 50% before the limit
# is enforced. So when you set the threshold to 10, up to 15 fields may appear,
# but if the number exceeds 15, the total amount of fields shown is limited to
# 10.
# Minimum value: 0, maximum value: 100, default value: 10.
# This tag requires that the tag UML_LOOK is set to YES.

UML_LIMIT_NUM_FIELDS   = 10

# If the DOT_UML_DETAILS tag is set to NO, doxygen will show attributes and
# methods without types and arguments in the UML graphs. If the DOT_UML_DETAILS
# tag is set to YES, doxygen will add type and arguments for attributes and
# methods in the UML graphs. If the DOT_UML_DETAILS tag is set to NONE, doxygen
# will not generate fields with class member information in the UML graphs. The
# class diagrams will look similar to the default class diagrams but using UML
# notation for the relationships.
# Possible values are: NO, YES and NONE.
# The default value is: NO.
# This tag requires that the tag UML_LOOK is set to YES.

DOT_UML_DETAILS        = NO

按需编辑完以后，执行 doxygen 命令，会在当前目录产生html目录，打开查看index.html即可
