The whole of my book on Building a Debugger is now available on Early Access!

It teaches you how to write a native code debugger from scratch.

There's lots of cats.

If you've already worked through the chapters of the first Early Access version, I've written a handy upgrade guide that shows you all the code changes you need to make to get up-to-date: https://github.com/TartanLlama/sdb/blob/main/early_access_upgrade.md

Some things in the book I think are cool:

• Walks you through implementing limited expression evaluation, so you can call functions inside the running process

• Teaches you to write a DWARF parser

• Builds a full stack unwinder based on DWARF unwind tables

• Traces shlib loading

@TartanLlama what’s the target audience in terms of programming level ? Beginners, medium, senior programmers ?

@orphadel intermediate and above I'd say. I try to keep things accessible, but some of the concepts are intrinsically complex

@TartanLlama I have some students who are interested in building a time travel debugger, am pointing them to your book for base knowledge!

@va2lam great! There's a small bit at the end about time travel debugging, but I don't cover it in detail

@TartanLlama yeah I figured it would be a useful first step for understanding debuggers, even better if it mentions time travel at all

@TartanLlama Looks amazing! Will I be able to follow this on an ARM + macOS system?

@eh I've heard a couple people doing this with UTM emulation, but haven't heard back about completing the whole thing, it's on my checklist before full release.

If you felt like building the sample codebase and running the tests to see if they all pass on your system, that would mean that everything in the book should work fine: https://github.com/TartanLlama/sdb/tree/main

If it works, please do let me know!
