Make sure doxygen is running as part of the build script.

These install doxygen and graphviz, which is used to generate the graphs.

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

Then to generate a doxygen config file called Doxyfile for the docs for a folder.

cd folder/with/code
doxygen -g

Then the file Doxyfile in folder/with/code needs to be edited.

nano Doxyfile

Change the project name. For example, for this directory I called it "Robot Application"

PROJECT_NAME = "Title for these Docs"

Change the output directory so it's not vomiting all over your directory.

OUTPUT_DIRECTORY = docs
NOTE: Traditionally documentation is not committed because of the bloat that it adds. Don't add it to your svn/git commits.

Enable recursion so it will go into folders to document them.

RECURSIVE = YES

Changes these values to document things that aren't correctly or normally documented using doxygen

EXTRACT_ALL = YES
EXTRACT_PRIVATE = YES
EXTRACT_PACKAGE = YES
EXTRACT_STATIC = YES
EXTRACT_ANON_NSPACES = YES

Enable these to generate the call and inheritance graphs.

HAVE_DOT = YES
CALL_GRAPH = YES
CALLER_GRAPH = YES
