everything-dbg

Install all debug symbols for a Debian package in one command.

Why?

Let's say you want to debug or profile xfce4-terminal. To get debugging symbols for it on Debian (and its derivatives like Ubuntu or elementary OS) you'd run:

$ sudo apt install xfce4-terminal-dbg

However, debugger still shows a lot of unknown function calls! What do?

Turns out you have only installed debugging symbols for xfce4-terminal itself, but not for any of its libraries (gtk+, libvte, etc) which shoulder most of the actual work. There was no easy way to install debugging symbols for all the dependencies... until now.

Introducing everything-dbg

$ everything-dbg xfce4-terminal will print names of -dbg packages for all dependencies of the specified package. Simply pass it to apt install to install them.

Features:

  1. Fetches debugging symbols for dependencies of dependencies and so on all the way down to libc6-dbg.
  2. Supports -dbgsym packages: uses -dbgsym package if it's available, otherwise uses -dbg
  3. Checks that every -dbg package is actually installable, prints warnings and skips the ones that cannot be installed (Ubuntu has a bunch of -dbg packages which cannot be installed due to dependency issues)
  4. Clean output on stdout, all messages go to stderr, so it can be easily combined with other tools.

Installation

sudo apt install apt-rdepends
git clone https://github.com/Shnatsel/everything-dbg.git
