This page describes how to setup osc to build for Mer inside the Mer SDK and a some basic osc usage.

Contents

[edit] Introduction

osc is a tool to interact with OBS servers. It provides many functions including:

  • Creating, modifying and deleting the information about projects and packages and downloading/uploading their source code and packaging
  • Managing the repositories/targets that projects/packages build against
  • Preparing and running local builds of packages
  • Making and managing requests to modify packages in projects (so called SRs or Submit Requests)

[edit] Preparation

You'll need a merproject.org account and have the Mer Platform SDK setup.

[edit] Getting Access

Just use your Mer Project username (from the Mer bugzilla)

[edit] Setup osc credentials

Once your account is enabled, run osc the first time with

osc -A https://api.merproject.org ls mer-tools:devel

This will ask you to enter your merproject.org user account details and will simply return a list of packages in the devel level mer-tools project.

From now on, you can omit the API URL in the command.

osc ls mer-tools:devel

[edit] Create a home project

Visit https://build.merproject.org and select the "create home" option.

[edit] Setup a Mer build project

For any commands below the ACC environment variable should be set to your OBS username. eg:

 export ACC=lbt

[edit] Adding repos to your home

You can add repositories on the OBS or edit them locally with this command which will launch an editor for you:

 osc meta prj home:${ACC} -e

Use the 'lbt' home project as a guide; it has a target (ie a repository of binaries used to make a build root) for Mer_Core_i486 and looks like this:

 <project name="home:lbt">
   <title>lbt's Home Project</title>
   <description></description>
   <person userid="lbt" role="maintainer"/>
   <person userid="lbt" role="bugowner"/>
   <person userid="bossbot" role="maintainer"/>
   <repository name="Mer_Core_i486">
     <path repository="standard" project="Mer:MDS:Core:i586"/>
     <arch>i586</arch>
   </repository>
 </project>

If you need to build for ARM too then you can add a suitable target just before the </project> :

 <repository name="Mer_Core_armv7hl">
   <path repository="Core_armv7hl" project="Mer:MDS:Core:armv7hl"/>
   <arch>armv8el</arch>
 </repository>

See the OBS architecture naming page for more info.

[edit] Creating projects

You may create sub-projects using the web user interface (see the 'Subprojects' tab for your home project).

These are useful for building against different targets; eg a NemoApps project may point at various Nemo build targets.

[edit] Creating packages

To create a package you could do:

 osc meta pkg home:${ACC}:tools powertop -F - << EOF
 <package project="home:${ACC}:tools" name="powertop">
   <title>PowerTOP</title>
   <description>
 PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where you can experiment with various power management settings for cases where the Linux distribution has not enabled those settings.

 </package>

[edit] Tips and Tricks

[edit] Specifying local build targets and cache location

The ~/.oscrc comments describe how these work. Some useful values are:

  • build-root : if you can set this to use an SSD it will make a big difference to local builds
  • packagecachedir : a large cache can be very useful. It's not cleaned automatically.

[edit] Using Multiple API URLs

If you're using osc with other API URLs, you can edit ~/.oscrc and add each of them and assign them aliases

[https://api.merproject.org/]
user = your-merproject.org-username
pass = your-merproject.org-password
aliases = cobs
 
[https://api.opensuse.org]
user = username
pass = password
aliases = opensuse

Note the apiurl value in that file defines the default OBS instance.

And to use the alias:

osc -A mobs ls
osc -A opensuse ls

[edit] Copying packages between OBS instances

It is possible (and quite handy :)) to copy packages between different OBS instances:

osc -A source_api copypac -t destination_api source_prj source_pkg destination_prj [destination_pkg]

Examples:

With the above mentioned aliases:

osc -A opensuse copypac -t cobs Application:Geo monav home:MartinK:nemo

Just with the API URL:

osc -A https://api.opensuse.org copypac -t https://api.merproject.org Application:Geo monav home:martink:nemo

NOTE: You usually need a user account on both OBS instances.
