Doxygen-1.10.0

Introduction to Doxygen

The Doxygen package contains a documentation system for C++, C, Java, Objective-C, Corba IDL and to some extent PHP, C# and D. It is useful for generating HTML documentation and/or an off-line reference manual from a set of documented source files. There is also support for generating output in RTF, PostScript, hyperlinked PDF, compressed HTML, and Unix man pages. The documentation is extracted directly from the sources, which makes it much easier to keep the documentation consistent with the source code.

You can also configure Doxygen to extract the code structure from undocumented source files. This is very useful to quickly find your way in large source distributions. Used along with Graphviz, you can also visualize the relations between the various elements by means of include dependency graphs, inheritance diagrams, and collaboration diagrams, which are all generated automatically.

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Installation of Doxygen

[Note]

Note

When untarring this package, you may see messages such as Ignoring unknown extended header keyword 'LIBARCHIVE.xattr.com.apple.TextEncoding'. These messages are harmless, and can be safely ignored.

First, fix up some python scripts:

grep -rl '^#!.*python$' | xargs sed -i '1s/python/&3/'

Install Doxygen by running the following commands:

mkdir -v build &&
cd       build &&

cmake -G "Unix Makefiles"         \
      -DCMAKE_BUILD_TYPE=Release  \
      -DCMAKE_INSTALL_PREFIX=/usr \
      -Wno-dev .. &&

make

To test the results, issue: make tests.

If you wish to generate the package documentation, you must have Python, TeX Live (for HTML docs) and Ghostscript (for PDF docs) installed, then issue the following command:

cmake -DDOC_INSTALL_DIR=share/doc/doxygen-1.10.0 -Dbuild_doc=ON .. &&

make docs

Now, as the root user:

make install &&
install -vm644 ../doc/*.1 /usr/share/man/man1

If you have generated the package documentation, then the man pages are automatically installed, and you do not need to run the last install ... command.

Command Explanations

-Dbuild_wizard=ON: Use this switch if Qt5 is installed and you wish to build the GUI front-end.

-Dbuild_search=ON: Use this switch if xapian is installed and you wish to build external search tools (doxysearch.cgi and doxyindexer).

-Duse_libclang=ON: Use this switch if llvm with clang are installed, to add support for libclang parsing.

Configuring Doxygen

There is no real configuration necessary for the Doxygen package although three additional packages are required if you wish to use extended capabilities. If you require formulas to create PDF documentation, then you must have texlive-20230313 installed. If you require formulas to convert PostScript files to bitmaps, then you must have ghostscript-10.03.0 installed.

Short Descriptions

doxygen

is a command-line based utility used to generate template configuration files and then generate documentation from these templates. Use doxygen --help for an explanation of the command-line parameters

doxywizard

is a GUI front-end for configuring and running doxygen

doxyindexer

generates a search index called doxysearch.db from one or more search data files produced by doxygen. See, e.g. https://javacc.github.io/javacc/

doxysearch.cgi

is a CGI program to search the data indexed by doxyindexer
