OBS projects setup

Building for different targets in OBS

You might want to build packages for different targets like Debian or Opensuse. There are two ways to do that :

• inter-OBS link provided by build.opensuse.org

• download on demand against a static repository

Download on Demand

Steps for debian :

• Choose a fast mirror of the repository you want to build against. It has to be static as cached information will not be refreshed automatically by OBS.

For example for Debian stable I use http://debian.osuosl.org/debian/

• Locate the Packages file for the dist and architecture you want. For squeeze (stable) i386 it is at :

http://debian.osuosl.org/debian/dists/squeeze/main/binary-i386/Packages.gz

• Create a project using the web UI or the osc. For example to create a toplevel Debian:6.0 using osc :

osc -A apiurl meta prj -e Debian:6.0

• Fill the project meta similar to the following xml :

<project name="Debian:6.0">

 <title>Debian stable (Squeeze)</title>
 <description>Debian 6.0 stable (Squeeze) using download and demand from http://debian.osuosl.org/debian/dists/squeeze</description>
 <person userid="Admin" role="maintainer"/>
 <person userid="Admin" role="bugowner"/>
 <download mtype="debmd" arch="i586" baseurl="http://debian.osuosl.org/debian/" metafile="Packages"/>
 <build>
   <disable/>
 </build>
 <publish>
   <disable/>
 </publish>
 <repository name="standard">
   <arch>i586</arch>
 </repository>

</project>

Notes :

• mtype is debmd for debian
• arch matches this repository and Packages file to an OBS scheduler, so debian i386 will be handeled by the i586 scheduler
• baseurl is used to construct the URL of the packages mentioned in the Packages file
