What is DDD?

GNU DDD is a graphical front end for the command-line debugger GDBand the variant CUDA-GDB. Besides usual frontend features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.

Other command-line debuggers can be used with DDD, but the interface development is no longer active in version 3.4: DBX, Ladebug, JDB, XDB, the Perl debugger, the bash debugger bashdb, the GNU Make debugger remake, or the Python debugger pydb.

For more information (and more screenshots), see theDDD Manual.

Where do I get DDD source?

DDD can be found at/gnu/ddd/ onftp.gnu.org, onSavannahor at any GNU FTP mirror near you. The ddd/ directory contains the DDD source distribution:

ddd-version.tar.gz-- this package is the one you want. It includes

the complete DDD source code,
building instructions, as well as
the DDD manual in TeXinfo, Info, PostScript, and PDF formats.

Where do I get DDD binaries?

The FSF does not distribute DDD binaries.

DDD binaries for GNU/Linux are typically available via your GNU/Linux distributor:

What do I need to build DDD?

To build DDD from sources, you need

The DDD source distribution (see above).
The GNU compiler collection (GCC), version 3.0 or higher (or another ISO C++ compiler).
The Motif user interface toolkit, version 2.3.4 or higher. The simplest way to build and install DDD is:

Unpack the DDD source distribution
Change into the ddd-version subdirectory
Type ./configure && make.
If the above doesn't give an error, type make install to install the program. (Depending on your OS and permission level you might need to use sudo make install to install instead.) To run DDD, you need the GNU debugger (GDB), version 4.16 or later.

How do I get started with DDD?

The DDD Manual contains a detailed tutorial. It is available as a PDF or web page.

DDD--A Free Graphical Front-End for UNIX Debuggersby Andreas Zeller and Dorothea Luetkehaus, Technische Universitaet Braunschweig, Germany (Informatik-Bericht No. 95-07, 7 August 1995).

Here are some free third-party tutorials on the Web:

_Linux Magazin_has articles (in German) on debugging with GDB and DDD.
LinuxFocus has a DDD tutorial in English,Spanish,German,French,Korean, andTurkish.

Third-party books (non-free):

The art of debugging with GDB, DDD, and Eclipse, Norman S. Matloff, Peter Jay Salzman, No Starch Press, San Francisco, 2008

Where do I get DDD releases?

The DDD Subversion repository (containing all versions of DDD, including the very latest changes) is available viahttps://savannah.gnu.org/projects/dddunder "Subversion Repository".

Buildable tar files are available: Alpha Releases and Final Releases.

I have found a bug! How do I report it?

You can report bugs on the bug tracker. Before you do this, please check the following:

Please try to see whether your bug has already been reported. You canbrowse orsearchthe bug tracker.
Please read the section ``Bugs and How to Report Them'' toward the end of the DDD Manual.
Be sure to include a copy of your ~/.ddd/log file which tells your DDD configuration as well as the interaction between DDD and the underlying command-line debugger.
Remember, the more (relevant) information you put in your bug report, the more likely it is to be fixed rapidly.

The purpose of reporting a bug is to enable the bug to be fixed for the sake of the whole community of users. You may or may not receive a response; the maintainers will send one if that helps them find or verify a fix. Most GNU maintainers are volunteers.

If you are willing to help fixing DDD bugs, you can subscribe to the bug-ddd mailing list or access its archives.

I have a question regarding DDD. Where do I get assistance?

We have a general-purpose mailing list devoted to DDD. You can ask any questions to ddd at gnu.org. Patches and new releases are also announced here. Subscription info and mailing list archives are available. Owing to abuse by spammers, it is necessary to subscribe before posting to the list.

Where can I learn more about the debuggers DDD uses?

As mentioned above, DDD runs a number of debuggers under the scenes. One can issue commands directly to those debuggers. Below are links for these debuggers:

GNU Debugger: gdb
CUDA-GDB: cuda-gdb

Where can I learn more about debugging and debuggers?

Here are some other related resources:

Motif.A window library needed to compile DDD.
KDbg.A KDE-based GDB Interface with inspection of variable values in a tree structure.
Valgrind.No-one developing C or C++ code under Linux/x86 should be without it. Have fun with DDD!
