Buildroot is a widely popular, easy to use and easy to extend embedded Linux build system used by a large number of companies and hobbyists to build small, highly customized Linux systems for embedded devices. Completely vendor neutral, offering more than 1200 packages, it is driven by a vibrant open-source community, with about 100 contributors to each release every three months.
In this talk, we'll propose a deep dive into the Buildroot internals through a description of how the core of this build system works. By looking at how toolchains are integrated, how the package infrastructures are working, and how the entire build process is organized, this talk will help Buildroot users and developers understand better what their build system is doing, and how to extend it for their needs.
