[CppIndiaCon 2022] Getting most out of GDB by Greg Law

If you write C++ on Linux then chances are that you use GDB at least sometimes. Many don’t realise how much GDB can you do for you. It’s a lot more than just break, step, print. This talk is packed with short and simple examples demonstrating the more advanced features of GDB, including its powerful Python scripting, different user interfaces, dynamic printf, multi-process debugging, advanced types of breakpoints and watchpoints, even time-travel debugging! Developers spend relatively little time typing in the code and much more getting it to work - you can’t be a great programmer without being great at debugging. And you can’t be great at debugging if you’re not able to get the most out of the tools available. Few slides, lots of demos, lots of things covered - you will leave the talk able to debug difficult problems much more quickly than you could before.

Dr Greg Law is the founder of Undo. Greg has over 20 years experience in the software industry and has held development and management roles at companies including the pioneering British computer firm Acorn, as well as fast-growing start ups like NexWave and Solarflare. Greg was determined to build a tool to help developers ease the pain of debugging complex software, so he founded Undo from his garden shed back in 2012. Undo is now established as the time travel debugging company for Linux software development. Learn more at undo.io
