GDB is REALLY easy! Find Bugs in Your Code with Only A Few Commands

Join me and learn how to debug a program written in C using GDB. In this video, we go over how to compile a program written in C so that GDB can present it, as well as the basic commands used in GDB to debug a program.

Need more low level channels like this. Thank you!

One of the clearest, least daunting videos about GDB. I actually feel I could do it.

[BorisGrishenco]

Best videos about C and embedded programming. I love the way you put motivation on the table. And I really appropriate the short length of the video and effort put into it.

Ah, gdb my old friend. We don't talk much, but when we do the conversation is invaluable. I tracked down a bug in my php code with gdb for a long lived demon process that was crashing from time to time. Running that program in gdb for a few days until it finally reproduced the error that wasn't making it to the error handler made everything so much clearer. (This was a long time ago, and there was a bug in curl that was causing it, I since moved over to using the native file_get_contents functions for http requests and the bug went away.)

Thank you so much for this. Friendship ended with debug print statements, now gdb is my best friend.

I noticed a minor mistake when you explaining the failure instruction. This is AT&T assembly syntax (not Intel) so "mov %eax, (%rdx)" means moving the value in %eax to the one referenced by (%rdx), not the other way around.

[BobBeatski]

That was a really useful succinct introduction to getting going with GDB. Thanks !

[dertom]

Thanks a lot! Always wanted to know how to use gdb manually and this is a perfect starting point! 👍

[torf]

first time using GDB, and this video gave me the tools do everything I normally need in my IDE debugger just fine. Already fixed 2 or 3 bugs in the past few days that would've been a pain in the ass with only print debugging.

[evgusk]

Never used gdb alone. Always with a front-end. Very interesting to see how to use it directly. thnx!

[a.v]

Great Tutorial man. Its so intresting to see the assembly code!

[klimmesil]

This is really good quality content for beginners. I'm showing this to my classmates that struggle with gdb, and they all seem to like it too. You go straight to the point, give a good concrete example and you speak well. Thank you!

[TheDeclancox]

Nice, succinct and to the point! Thank you!

[alol-alol]

Great video! gdb is one of those tools I know I should know much better. Please keep this stuff coming!

[anthonyheak]

Great tutorial, learned something new, thanks!

[chandulanethmal]

Clear and very supportive explanation!

[TheTrek]

Great video - if you link the second video on GDB (mentioned in this video) - that be awesome

[Fernando-duuj]

Wow. Thank you so freaking much, buddy.

[Ms.Robot.]

Thanks! This was exactly what I needed. ❤️

I hope you do more forensic engineering

[FabioLima-sksq]

The explanation was simple and didactic. The audio is clear, it's helps a lot to flow of the idea.
Help me a lot for beginner in GDB, thank you !!
