DoxyGen

Doxygen is a program to generate developer's documentation out of a program's sourcecode. Parts of the sourcecode's comments are transformed into function descriptions. Doxygen can be used to

• create classes listings and explanation
• create functions listings and explanation
• create call-graphs

Install it

Note that you need to install graphviz to be able to create graphs. Install graphviz and doxygen as described at installing software, e.g.

for SUSE

yast -i graphviz
yast -i doxygen
yast -i doxywizard

for Kubuntu

apt-get install graphviz
apt-get install doxygen
apt-get install doxygen-gui

for Gentoo

emerge -a media-gfx/graphviz app-doc/doxygen
eix dox      # to see if there's an interface that you would want (like maybe mkdoxy)

Run it

If you are a beginner, best start with the program

doxywizard

TroubleShooting

Symptom

Solution

Edit your doxyfile (by default ~/Doxyfile), replace

SHORT_NAMES            = NO

by

SHORT_NAMES            = YES

and run doxygen again
