[[/Installation | Installing OpenSuse Build Service]] is a prerequisite for setting up a specific OBS project.
+
== Our Goals ==
 +
We want:
 +
* to allow freedom for developers to develop;
 +
* to provide a build service and SDK
 +
* to work with the core distro as much as possible
 +
* to provide excellent quality assured applications for our "app store";
 +
* to extend the core distro with a community supported Surrounds area for libraries and packages that are depended upon by more than one application.

Lets set out some basics about the OBS.
-
This currently refers to some inaccessible repos. I'll open them up as I get time.
+
# 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
 +
# It has packages - a package corresponds to a tarball and a spec/dsc
 +
# It has projects - a project is like a directory with packages
 +
# 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)
 +
# The repositories can also be used by devices to download binary packages.
-
Approach:
+
The 'trick' then, is to set up a structure of projects that we can use to support the publishing and sharing activities that we need.
-
* Copy all Nokia Fremantle Binaries to Fremantle:1.1:Std
+
-
* Create Fremantle:1.1:Bootstrap/<pkg> to create packages (use useforbuild = no?)
+
-
* Create Fremantle:1.1:Loaded to include additional binaries needed by OBS
+
-
* Create Fremantle:1.1 as the nominal target for :Extras and the main prjconf
+
-
(see https://projects.maemo.org/trac/maemoobs/wiki/Fremantle too)
+
Some tasks needed to get the OBS running:
 +
* [[/Installation|OBS Installation]] - a detailed guide on how the system was setup.
 +
* [[/Application QA Process|Application QA Process on the OBS]] - a proposal
 +
* [[/Chinook Setup|Setting up Chinook]] - WIP
 +
* [[/Fremantle_Setup|Setting up Fremantle]] - WIP.
 +
* [[/MeeGo_Setup|Setting up MeeGo]] - WIP.
 +
* [[/Cross_Setup|Setting up cross-building]] - started, not imported yet
 +
* [[/Autobuild|An OBS Autobuilder queue]] - not started
 +
* [[/Reporting|Reporting]] - not started
 +
* [[Task:Maemo_OBS|Task page for Maemo OBS]]

[edit] Our Goals

We want:

  • to allow freedom for developers to develop;
  • to provide a build service and SDK
  • to work with the core distro as much as possible
  • to provide excellent quality assured applications for our "app store";
  • to extend the core distro with a community supported Surrounds area for libraries and packages that are depended upon by more than one application.

[edit] Basics

Lets 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.

The 'trick' then, is to set up a structure of projects that we can use to support the publishing and sharing activities that we need.

Some tasks needed to get the OBS running:
