Hey everyone,
I'm trying to attach to a process that is crashing so I can debug the source code. I've tried this:

stop at "file.cpp":line#
However, nothing ever breaks. The service crashes and restarts, but I never see it hitting the code. I've tried to use a core file, but... (2 Replies)

Hi,
We are porting a virtual machine application which emits native PowerPC instructions. The instructions are written to the data segment and are then executed, similar to the JIT / hot spot technology used in the Java VM.
The problem is that the AIX debugger (dbx) will not show me stack... (3 Replies)

NAME
ddd - The Data Display Debugger
SYNOPSIS
ddd [--help] [--gdb] [--dbx] [--ladebug] [--wdb] [--xdb] [--jdb] [--pydb] [--perl] [--debugger name] [--[r]host [[username@]hostname]]
[--trace] [--version] [--configuration] [options...] [prog[core|procID]]
but usually just
ddd program
DESCRIPTION
DDD is a graphical front-end for GDB and other command-line debuggers. Using DDD, you can see what is going on "inside" another program
while it executes--or what another program was doing at the moment it crashed.
DDD can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act:
o Start your program, specifying anything that might affect its behavior.
o Make your program stop on specified conditions.
o Examine what has happened, when your program has stopped.
o Change things in your program, so you can experiment with correcting the effects of one bug and go on to learn about another.
"Classical" UNIX debuggers such as the GNU debugger (GDB) provide a command-line interface and a multitude of commands for these and other
debugging purposes. DDD is a comfortable graphical user interface around an inferior GDB, DBX, Ladebug, XDB, JDB, Python debugger, or Perl
debugger.
DDD is invoked with the shell command ddd. You can open a program to be debugged using `File->Open Program' (the `Open Program' item in
the `File' menu. You can get online help at any time using the `Help' menu; for the first steps, try `Help->What Now?'. Quit DDD using
`File->Exit'.
More information on DDD is contained in the DDD Manual. You can read the text-only version in DDD (via `Help->DDD Reference') or in Emacs
(as Info file). Full-fledged HTML, PostScript, and PDF versions are available online via the DDD WWW page,
http://www.gnu.org/software/ddd/
OPTIONS
These are the most important options used when starting DDD. All options may be abbreviated, as long as they are unambiguous; single
dashes may also be used. DDD also understands the usual X options such as `-display' or `-geometry'; see X(1) for details.
All arguments and options not handled by DDD are passed to the inferior debugger. To pass an option to the inferior debugger that con-
flicts with an X option, or with a DDD option listed here, use the `--debugger' option, below.
--configuration
Show the DDD configuration settings and exit.
--dbx Run the DBX debugger as inferior debugger.
--debugger name
Invoke the inferior debugger name. This is useful if you have several debugger versions around, or if the inferior debugger cannot
be invoked as `gdb', `dbx', `xdb', `jdb', `pydb', or `perl' respectively.
This option can also be used to pass options to the inferior debugger that would otherwise conflict with DDD options. For instance,
to pass the option `-d directory' to XDB, use:
ddd --debugger "xdb -d directory"
If you use the `--debugger' option, be sure that the type of inferior debugger is specified as well. That is, use one of the
options `--gdb', `--dbx', `--xdb', `--jdb' `--pydb', or `--perl' (unless the default setting works fine).
--gdb Run the GDB debugger as inferior debugger.
--help Give a list of frequently used options. Show options of the inferior debugger as well.
--host [username@]hostname
Invoke the inferior debugger directly on the remote host hostname. If username is given and the `--login' option is not used, use
username as remote user name.
--jdb Run JDB as inferior debugger.
--ladebug
Run Ladebug as inferior debugger.
--perl Run Perl as inferior debugger.
--pydb Run PYDB as inferior debugger.
--rhost [username@]hostname
Run the inferior debugger interactively on the remote host hostname. If username is given and the `--login' option is not used, use
username as remote user name.
--trace
Show the interaction between DDD and the inferior debugger on standard error. This is useful for debugging DDD. If `--trace' is
not specified, this information is written into `$HOME/.ddd/log', such that you can also do a post-mortem debugging.
--version
Show the DDD version and exit.
--wdb Run the WDB debugger as inferior debugger.
--xdb Run XDB as inferior debugger.
A full list of options, including important options of the inferior debugger, can be found in the DDD manual.
