Writing a Linux Debugger | C++ | Systems Programming

Learn how to build a Linux debugger from scratch, covering core features like breakpoints, single stepping, and variable inspection. Ideal for developers interested in low-level systems programming.

Introduction

This tutorial series teaches how to write a Linux debugger from scratch, covering topics such as launching and controlling the debugee process, reading registers and memory, parsing DWARF debug information, and implementing source-level debugging features.

Highlights

• Learn how debuggers work under the hood
• Implement core debugging features like breakpoints, single stepping, and variable inspection
• Use modern C++ and leverage libraries like Linenoise and libelfin
• Applicable to debugging C/C++ programs on Linux

Recommendation

This course is recommended for developers who want to gain a deeper understanding of how debuggers work and how to implement their own debugging tools. It covers a wide range of topics relevant to low-level systems programming and is a great learning resource for those interested in compiler toolchains and program analysis.
