As programmers, we all make errors. Certainly, most of us at least have tried placing "printf" statements in our code hoping to catch the errors, however, we need to know more than that. Debugger is a good tool for tracing bugs. In this tutorial, we will show you how to use gdb -- a "GNU" debugger.

January 10, 2025 - In this article we have discussed GDB (GNU Debugger) which is a powerful tool in Linux used for debugging C programs. We have discussed some of the following steps so that we can compile your code with debugging information, run GDB, set breakpoint, examine variables, and analyze program behavior.

February 27, 2024 - This article is the first in a series demonstrating how to use the GNU Debugger (GDB) effectively to debug applications in C and C++. If you have limited or no experience using GDB, this series will teach you how to debug your code more efficiently.

To start gdb, just type gdb at the unix prompt. Gdb will give you a prompt that looks like this: (gdb). From that prompt you can run your program, look at variables, etc., using the commands listed below (and others not listed).

Provides a brief description of a GDB command or topic. Plain help lists the possible topics.

April 4, 2025 - This tutorial is for folks in courses like the UMN's CSCI 2021 or UMD's CMSC 216 which require use of GDB to work programs and perform debugging exercises like Bryant and O'Hallarons notorious "Binary Bomb" project.

August 9, 2016 - gdb Debugging Full Example (Tutorial): analyzing ncurses on Linux. This gdb analysis example includes full output, not just the commands used.

GDB, short for GNU Debugger, is the most popular debugger for UNIX systems to debug C and C++ programs. This tutorial provides a brief introduction on how to use GDB commands to ensure the programs are error-free.

(gdb) n 9 for (int j = 0; j <= number; j++) { (gdb) n 10 fact = fact * j; (gdb) n 9 for (int j = 0; j <= number; j++) { (gdb) print fact $2 = 0 (gdb) n 13 return fact; (gdb) quit The print command (abbreviated p) reveals that the value of fact never changes. Note that the function is returning a value of 0 for the function call ComputeFactorial(number=0).

May 29, 2024 - To break down how GDB works, here is an example of a simple debugging flow of an C++ application. For the sake of this tutorial we’ll be working with the following example code:

GDB Tutorial is comprehensive guide to learn gdb in easy steps. This tutorial covers instroduction of gdb, how to install it and explains how to use gdb and gdb commands with example.

This is the Tenth Edition, of Debugging with GDB: the GNU Source-Level Debugger for GDB (GDB) Version 18.0.50.20251208-git.

Sample session – Short Tutorial – Long Tutorial · gcc -g myprogram.c · Compiles myprogram.c with the debugging option (-g). You still get an a.out, but it contains debugging information that lets you use variables and function names inside GDB, rather than raw memory locations (not fun).

June 14, 2009 - This is a very quick-and-dirty guide meant to get you started with the GNU Debugger, gdb, from the command line in a terminal. Often times gdb is run via an IDE, but many people out there shun IDEs for a variety of reasons, and this tutorial is for you!
