These macros may then be used in GDB just like any other symbol in your program. The one specific option worth adding is -g3, which tells the compiler to include debugging information about the macros ( #define FOO. So ignore advice to use -ggdb or -gdwarf-2. Specifying the exact debug format is no longer necessary (or desirable) DWARF has been the default debugging information format on GNU/Linux for many years. I also always have the toolchain emit debugging information. Optimization can cause GDB to behave in surprising ways if you are not aware of what might be happening 'under the covers.' I always use the C compiler option -O0 (that's the letter O followed by the number zero) to build executables during the development cycle. Watch for a future article on optimization. TL DR: Don't debug applications with optimization if you can avoid it. That is trivial advice, but GDB's public IRC channel (#gdb) sees these issues often enough that they warrant mentioning. Let me get the (all-too-often-not-so) obvious out of the way: For the best debugging experience, build applications without optimization and with debugging information. I use GDB daily, and these tips and tricks are the ones that I (and many other advanced GDB users and developers) use to streamline our debugging sessions.īecause this is the first article in the series, allow me to follow the recommendation of the GDB Song and start at the very beginning: How to run GDB. Instead of simply demonstrating a handful of useful commands, each article in this series will focus on one aspect of using GDB from the perspective of someone who develops GDB. New GDB users just might as well read (or sing) the official GDB Song! The majority of GDB tutorials available on the web consist of little more than introductions to the basic list, break, print, and run commands. In addition to providing developer tips and tricks for many GDB commands, future articles will also cover topics such as debugging optimized code, offline debugging (core files), and server-based sessions ( aka gdbserver, used in container debugging). If you are already a seasoned professional using GDB, perhaps you will discover something you haven't seen before.

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