All its resources, like Ddd*defaultFont, can pick from only those legacy fonts, which don’t properly render UTF-8.

For dark mode in the code window, console, and data display panel, set these resources: Ddd*XmText.background: blackĭdd*graph_idColor: white UTF-8 renderingīy default, DDD uses X core fonts. Set Ddd*saveOptionsOnExit: off to prevent DDD from putting the values back.ĭDD’s default color scheme is a bit glaring.Delete all Ddd*gdbSettings other than the prompt ones above, and.
I want ~/.gdbinit to be the source of truth. While specifying all settings in ~/.ddd/init might make for deterministic behavior on local and remote debugging sessions, it’s inflexible. Honoring gdbinit changesĪs mentioned, DDD probes and saves all GDB settings during first launch. That text overrides the regular prompt, causing GDB to output not set as its actual prompt. GDB reports the value as not set, which DDD interprets – not as the lack of a value – but as text to set for the extended prompt. The incorrect detection is especially bad for extended-prompt. However, it interprets the results wrong for these settings: It probes by running show settingname for all settings. ddd/init file for consistency in future runs. The root of the problem is that during DDD’s first run, it probes all GDB settings, and saves them in to its. In ~/.ddd/init include this code: Ddd*gdbSettings: \ To fix this error, you must explicitly set the prompt and unset the extended-prompt. However, DDD never sees that prompt because it incorrectly changed the prompt at startup. The freeze happens because DDD is looking for the prompt (gdb). Upon starting DDD, the first serious error you’ll run into is the program locking up with this message: Waiting until GDB gets ready. This causes some problems, but there are workarounds. It parses the standard text interface, essentially screen scraping GDB’s regular output. Newer front-ends use GDB’s unambiguous machine interface (MI), but DDD never got updated for that. DDD screenshot Fixing DDD freeze on startupĪs a front-end, DDD translates user actions to text commands that it sends to GDB. DDD can also control GDB sessions remotely over SSH. However, it has a lot of features delivered in a 3MB binary, with no library dependencies other than a Motif-compatible UI toolkit. It’s fairly ancient, and requires configuration changes to work at all with recent versions of GDB. Ultimately I chose option four, with the Data Display Debugger (DDD). no historical value tracking for variables (aside from GDB’s Linux-only process record and replay).no interactive structure/pointer exploration.mouse scroll wheel didn’t work for me on OpenBSD+xterm.no ability to set or clear breakpoints by mouse.no persistent window to display variables or the call stack.In my experiments, the TUI mode (option two) seemed promising, but it has some limitations: Front ends either use the GDB machine interface (MI) to communicate, or they screen scrape sessions directly. Use a graphical front-end that communicates with an “inferior” GDB instance.Some good examples are projects like gdb-dashboard and gef. Customize the UI using scripting, sourced from your.It’s easier to trace execution through the code and spot breakpoints than in the default interface.

The TUI creates Curses windows for source, registers, commands, etc.
Then you’ll be comfortable on any system with GDB installed. Ordered from basic to complicated, they are: There are four ways to customize this interface. You need to explicitly ask to print the source code being debugged, the values of variables, or the current list of breakpoints. It assumes you’re familiar with the basics of debugging, like breakpoints, stepping, inspecting variables, etc.īy default, GDB provides a terse line-based terminal. This article is a set of miscellaneous configuration and scripting tricks that illustrate reusable principles. Its interface is a little cryptic, but learning GDB pays off. GDB is an old and ubiquitous debugger for Linux and BSD systems that has extensive language, processor, and binary format support.
