Buildroot Developers Meeting, 3-4 November 2012, Barcelona Spain

What is Buildroot ?

Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system. Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a bootloader image. Buildroot is useful mainly for people working with small or embedded systems, using various CPU architectures (x86, ARM, MIPS, PowerPC, etc.) : it automates the building process of your embedded system and eases the cross-compilation process.

Meeting in Barcelona

The Buildroot community is organizing a meeting on Saturday November 3rd and Sunday November 4th, for Buildroot developers and contributors. This meeting will be a mixture of discussion and hacking session around the Buildroot project. This meeting takes place right before the Embedded Linux Conference Europe, in order to make it easy for participants to attend both events.

List of topics to discuss

  • Interaction between Buildroot configuration options to select architecture specifities (architecture variant, soft-float vs. hard-float, etc.) and the multilib variants available in external toolchains. Proposed by User:ThomasPetazzoni.
  • Status on the community organization. Has patchwork improved things? Are patches taken into account in a faster way? Proposed by User:ThomasPetazzoni.
  • What are the next "big" things for Buildroot? Proposed by User:ThomasPetazzoni.
  • Documentation refactoring? Proposed by Samuel Martin.
  • Autobuilder tests: needed improvements, future work. Proposed by User:ThomasPetazzoni.
  • The _AVAILABLE mechanism, and how to properly handle dependency on toolchain options (discuss the proposal made by Yann E. Morin). Proposed by User:ThomasPetazzoni.
  • Discuss (and, if approved, implement) the split between _LICENSE and _REDISTRIBUTE for legal-info. I think this won't take much more than 10 minutes chat + 10 minutes hack. Proposed by Luca Ceresoli.
