Install all debug symbols for a Debian package in one command.
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.
$ 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:
- Fetches debugging symbols for dependencies of dependencies and so on all the way down to libc6-dbg.
- Supports -dbgsym packages: uses -dbgsym package if it's available, otherwise uses -dbg
- 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)
- Clean output on stdout, all messages go to stderr, so it can be easily combined with other tools.
