Data Display Debugger

GNU DDD, the Data Display Debugger, is a GUI to command-line debuggers like GDB, DBX, JDB, XDB, Ladebug, WDB, the Perl debugger, or the Python debugger. It provides a graphical data display where complex data structures can be explored incrementally and interactively.

            The version shown here is not what's on the GNU server
            The version shown here at freshmeat is 3.3.5, but the
            newest official version (on the GNU site) seem to be 3.3.1.
            And the 3.3.5 version download link points to a different
            project's page (bashdb). Why?

            And the 3.3.5 version is not buildable. There is a parsing
            error and then the compiler consumes a huge amount of
            memory so that the computer thrashes. It must be killed.

            Try out GVD


            I tried to use GVD and it seems even better
            than DDD. It uses GTK, it has syntax highlighting,
            has a nicer GUI, a better graphical display, etc.
            It would be nice to know other people's opinion
            regarding DDD x GVD.

            DDD is excellent.
            DDD is a gem. Many bugs can be detected right
            away with this tool. The GUI is very intuitive and
            has very nice features, supporting actions such as
            pointing into a avariable with the mouse and
            obtaining its value, or selecting a complex
            expression, clicking with the right button,
            and telling DDD to add a graphical display of its
            value. The graphical display of variables needs
            some more development to get more robust, but its
            very good already.
