GDB debugging tutorial for beginners
September 21, 2025 - Learn how to effectively debug C/C++ using GDB on Linux. Discover key GDB commands like backtrace & frame inspection to resolve core dumps.
Properly Learning GDB
A course would be overkill. Look for a cheat sheet, then use it to do some actual debugging. You'll find yourself looking up specific things and soon enough you will have explored everything. I will say, if you're on windows, I'd strongly suggest using the rad debugger (shameless self plug) by epic games / rad tools. It's on GitHub. More on reddit.com

r/C_Programming on Reddit: Properly Learning GDB
December 10, 2024 -
Hi all,
Anyone know of any courses for an intermediate-advanced C programmer to really learn GDB?
I've been using printf debugging for too long and only know the very basics of GDB debugging (taught alongside an O/S dev course I completed).
Courses would be my preferred method.

This is a brief description of some of the most commonly used features of gdb. To prepare your program for debugging with gdb, you must compile it with the -g flag.

GDB - Quick Guide
A symbol table works for a particular version of the program if the program changes, a new table must be created. Debug builds are often larger and slower than retail (non-debug) builds; debug builds contain the symbol table and other ancillary information. If you wish to debug a binary program you did not compile yourself, you must get the symbol tables from the author. To let GDB be able to read all that information line by line from the symbol table, we need to compile it a bit differently.

GDB Quick Guide
I found out I didn't need cgdb by the way, it was better to just gdb -tui on Debian. Less modem noise in the form of uninterpreted escape sequences too.
So it paid up to do gdb -help.
The guide doesn't mention watch or watch -l but it points to Debugging with GDB where you can find everything.
It is a good quick start, with a couple of examples.

Hello. So, by no means a pro yet, but I feel I have researched the subject enough to practice, and I have. So, those three blogs from Red Hat, concerning using Gdb instead of printf statements, where wildly interesting, I'm not sure how much time the technique saves, but I guess it saves some, and I also guess, while I write that this way of getting output doesn't disappear with screen refreshes. (The articles also show how to make your breakpoints reusable by the "save breakpoints" command, so you can edit them and reuse them for next session.) (The "#" works for a comment in the ini file, so I guess it also works for commenting out in breakpoint files you source in, so that some "break point commands" can be disabled). It's great even if it isn't Turbo Debugger, which was more visual, but you can break on values, and reuse your breakpoint commands, so in the end I feel having something not inferior. Part 1 Part 2 Part 3 And well, its a complex program, and I will eventually read the info manual, no matter how much I hate the info manuals, because this is a must. The --core command line options which lets you load a coredump from when your program crashed, and you can view values and see the stack trace, that feature justifies everything. IMHO. Oh, and on some slides from the University of Maryland, I learned about the "finish" command that finishes the current function you are in. :)

(gdb) break Traverse Breakpoint 2 at 0x2290: file main.c, line 20 The command break main stops at the beginning of execution. You can also set breakpoints at a particular line in a source file: (gdb) break 20 Breakpoint 2 at 0x2290: file main.c, line 20 When you run your program and it hits a breakpoint, you'll get a message and prompt like this: Breakpoint 1, Traverse(head=0x6110, NumNodes=4) at main.c:16 (gdb) In emacs, you can use C-c C-b to set a breakpoint at the current point in the program (the line you have stepped to, for example) or you can move to the line at which you wish to set a breakpoint, and type C-x SPC (ctrl-X followed by a space).
