19 Aug 2004 : "stripped" version temporarily removed from GeoCities web site - see below.

15 Aug 2004 : Released DDD v3.3.9 for Mac OS X

14 Dec 2003 : Released DDD v3.3.8 for Mac OS X.

Introduction

DDD is a graphical front-end for command-line debuggers such as GDB, the Perl debugger, or the Python debugger. Besides "usual" front-end features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.

For more information on DDD, visit the GNU DDD web page.

Additional support for DDD can be found in the DDD mailing list.

DDD for Mac OS X is the binary for DDD built from sources on Mac OS X.

The following is a sample screen shot of DDD for Mac OS X in action.

System Requirements

Requirements for DDD for Mac OS X :

• Mac OS X 10.2 or newer (tested with 10.2.6, 10.3.3)
• X11 X Window system (tested with "XFree86" v4.3.0, v4.4.0 "X11.app" v1.0)
• X11 X Window server (tested with "XDarwin" v1.2, v1.3; "X11.app" v1.0; "OroborOSX" v0.8.5, v0.9)
• X11 X Window window manager (tested with "windowmaker" v0.62.1X; "quartz-wm" v1.0; "OroborOSX" v0.8.5, v0.9)
• FreeType2 (tested with v1.3.1X - libfreetype v6.2, v6.3)
• LessTif or other OSF/Motif® compatible library (tested with LessTif v0.93.94)
• DDD (tested with v3.3.9)
• gnuplot (optional - not tested)
• To make use of DDD, a command-line debugger (the so-called `inferior' debugger) is necessary. It is recommended that you have previously installed the Mac OS X Developer Tools.

  - To debug binary executables, best results are achieved with GDB, the GNU debugger. (GDB 4.x is required; we recommend GDB 5.0 or later.) Using GDB, you can debug programs written in C, C++, GNU Java (`guavac'), GNU Ada (`gnat'), GNU Fortran (`g77'), GNU Chill and GNU Modula-2.

  - To debug Java bytecode programs, DDD supports JDB, the Java Debugger, as of JDK 1.1 and later.

  Please note: JDB is more a `proof of concept' than a real debugger. DDD does its best to overcome JDB's limitations, but if you have an alternative to DDD/JDB, try it first.

  To debug Python programs, DDD supports PYDB, a PDB extension. PYDB is included in the DDD distribution.

  To debug Perl programs, DDD supports the Perl debugger as of Perl 5.003 and later.

Most of these items are available from 3rd party sources, but the LessTif library and DDD are part of the DDD for Mac OS X installation.

Download

Files are stored as StuffIt (.sit) binary files, or Apple Disk Copy device image (.dmg) files, or MacBinary (.bin) files, or BinHex (.hqx) files. You may require an appropriate FTP client and/or web browser settings.

The ".mac" (or iDisk Public Folder for user "teague") web site appears to have more reliable file transfers.

There is not a direct download link to the file on the iDisk - look in the "3. Data Display Debugger" folder.

• DDD v3.3.9 for Mac OS X (v1.1 released 15 Aug 04).

  Due to difficulties hosting the "full" unstripped version of DDD for Mac OS X disk image on the GeoCities web site, this disk image is available as two separate versions - the "full" version and the "stripped" version.

  The only difference between the two versions is that all debugging symbols are removed from the "stripped" version. While the "stripped" version is perfectly usable, if you plan to debug DDD itself, you will probably want the "full" version. The "stripped" version is only available on the GeoCities web site. Other download locations have the "full" version for download. It is recommended you download the "full" version of DDD for Mac OS X from those sites.

  Update: 19 Aug 04 - the "stripped" version has temporarily been taken offline, as the upload to GeoCities (or at least my verification download) is being corrupted by the upload (or download) process. You will need to get the "full" version from one of the other sites.

  The FTP site is temporarily unavailable using FTP, but can be accessed via the AppleTalk Filing Protocol (AFP) - i.e. AppleShare.

Source Code

The source code for DDD is provided under the terms of the GNU General Public License. Since the standard DDD binary distributions don't include a binary distribution for Mac OS X, it is possible to take the standard DDD source distribution and build a binary for Mac OS X. The process for doing so, is explained in the documentation provided with DDD for Mac OS X.

The sources required, are available from :

• LessTif v0.93.94
• DDD v3.3.9

Change History

15 Aug 04 :

v1.1 Release of DDD v3.3.9 using LessTif v0.93.94.

What's new in DDD 3.3.9?

New features and minor improvements

• Support for PHP debugger has been added (1). This is essentially not tested.
• Source files in subdirectories should be located automatically when using dbx (tested on Solaris' dbx) (2).
• The perl version supported by DDD is now 5.8.x. The perl debugger changed between perl 5.6.x and perl 5.8.0, which made this update necessary. This change is not backwards-compatible. If it is not possible to upgrade your perl version to 5.8.x or newer, then you can simply install the file "perl5db.pl" from a recent perl distribution into your old perl tree.
• Through the maintenance menu ("ddd --maintenance"), it now possible to get a leak check of ddd if ddd is run under valgrind. This is only useful for ddd developers (or anybody that wants to help making ddd better).
• Several minor bugs fixed, some memory leaks plugged, more code clean-up done.
• A bug affecting platforms where the size of function pointers is 16 has been fixed.
• The settings window now starts at a larger, more reasonable size, and allows the user to resize it.

  Build fixes

• The configure machinery has been updated to conform more closely to the autoconf 2.5x requirements. Several bugs have been fixed.
• libiberty (which provides missing standard functions) is not linked by default anymore. configure has a new option '--with-libiberty' that enables the libiberty support if required. If nobody complains, libiberty will be unbundled in a next version.
• The libiberty distributed with ddd has been upgraded to the one included in GCC 3.4 20040116. It fixes some configuration problems.
• Builds with GCC 3.4, with IBM xlC on AIX, with Compaq/HP cxx on Tru64, on X11R5 based systems, with SGI CC on IRIX should be OK.
• Builds on HP-UX should now work out-of-the-box. Motif is linked statically and the Athena libraries are now found by default.
• Builds without Motif/Lesstif available abort with an adequate message.
• Builds with readline support now work. readline is not bundled anymore.
• Builds without -DNDEBUG (i.e. with "assert" enabled) now work. Default build enables assertions (i.e. -DNDEBUG is not used).
• Several missing files in the distribution are now included.
• Cygwin is supported again.

  14 Dec 03 :

  v1.0 Initial release for DDD v3.3.8 using LessTif v0.93.91.

  What's new in DDD 3.3.8?

• The settings, signals, themes, and status-display windows are now resizable (if your window-manager can resize transient dialog windows).
• The settings are now read correctly when using gdb 5.x and 6.0.
• A memory corruption has been fixed in strclass.h.
• Several other memory management problems have been fixed.
• configure options --enable-builtin-app-defaults and --enable-builtin-vsllib should work again.
• Speed improvements, partly by avoiding the creation of temporary objects.
• Bug fixes in perl mode, thanks to Christian Hattemer and Peter Ernst.
• Builds on HPUX-10.20 now work OK (see the PROBLEMS file).
• The libiberty distributed with ddd has been upgraded to the one released with gcc-3.3.1. This helps DDD to build on NetBSD.

Known Problems

v3.3.9.

The text shown in the "Tip of the Day" dialogs sometimes contains unusual characters, such as "@", "¿" - this appears to be a LessTif bug, and is also seen on other platforms.

v3.3.8.

• Problems have sometimes been seen when setting the option for the paths GDB uses to search for source files in complex projects - if DDD gets confused, you may wish to quit DDD, remove the "~/.ddd/init" file, and restart DDD. This is a bug specific to Mac OS X, and will be fixed in the next version.
