MeeGo Build Infrastructure

The heart of the Build Infrastructure of MeeGo is the upstream project openSUSE Build Service (OBS). It is an automated system used for building software packages, collaboration of developers, release management, maintenance, and much more. Moblin started using OBS in June 2008 and released Moblin 2.0 and Moblin 2.1, as well as other derivative releases. OBS has proven to be a very reliable infrastructure that is quickly evolving. It is rich with features for distribution building and maintenance. The Linux Foundation is dedicated to the further development of OBS and has a team, including two full-time OBS maintainers, contributing to its development and its use by MeeGo and the Ecosystem.

MeeGo currently uses version 2.0.x of OBS and will soon switch to version 2.1. To learn more about version 2.1 and the additional features in it, see the upstream project details: roadmap.

There are 3 OBS instances that are relevant to MeeGo

• MeeGo core : essentially, if you're a core package maintainer/developer you get an account here
• MeeGo community : for anyone to build MeeGo apps (not available as of 27/10/10)
• openSuse : this is not for building *against* MeeGo... but we need to support MeeGo tools on many platforms and some of those get built on the openSuse OBS

Overview - What does it do?

Let's set out some basics about the OBS.

1. It's a build system. You put source on it and say "use this repository" and it builds a minimal SDK-like chroot using the deb/rpms it finds in that repository
2. It has packages - a package corresponds to a tarball and a spec/dsc
3. It has projects - a project is like a directory with packages
4. When a package is built it is "published" from the project where it was uploaded into a corresponding repository (which can be used to build other projects)
5. The repositories can also be used by devices to download binary packages.
