Master the inner workings of your x64 Linux system and expand your OS expertise by writing your very own debugger using C++. If debuggers seem like magic to you, there is no better way to demystify them than to write your own. This book will show you exactly how to do it, walking you through the entire process of building a debugger for x64 Linux systems using C++. As go from an empty filesystem folder to a fully fledged debugger capable of setting breakpoints, stepping through code, manipulating variables, and more. As you add features to your debugger, you’ll also pick up a wealth of knowledge about operating systems, compilers, software testing, and low-level programming that you can use in your day-to-day development. In this book, we’re particularly concerned with debuggers for compiled code that runs directly on your central processing unit (CPU), written in a language like C, C++, Rust, or FORTRAN. Debuggers for these programs need to interface directly with the operating system and the underlying hardware, which can lead us to some deep insights into how computers actually work. What Will We Build? Over the course of this book, we’ll build a command line debugger for native code. I’ll call the debugger sdb, for Sy’s Debugger, but you can call yours whatever you like.
