This section documents how to use the [http://build.opensuse.org openSUSE Build Service] with Mer. More on the openSUSE Buildservice [http://en.opensuse.org/Build_Service here].

A simple way to think of OBS is as a version control system for source tarballs and .dsc files and whenever you commit a tarball the build farm compiles it for you.

Over and above this OBS provides a local tool called osc that lets you do clean builds not only for your own OS and architecture but also for other distros and even other architectures (armel).

==Getting Started==

The first thing to do is to [[/Install OBS|install OBS]]. This will provide access to the tools and source used to build Mer.

Then you should become familiar with building an application using OBS but outside the Mer repository. This is explained in detail in [[/Application Building|Application Building]] which takes you through an example application.

==Mer Internals==

When you are comfortable building your own applications for Mer then you can look at the [[Mer/Packages|Mer Packages]] and start helping to improve Mer itself.

There are [[/Processes|processes]] used to manage the Mer packages which may include [[/UsingGitorious|Using Gitorious]].

The OBS [[/Cross Build|cross build]] page describes how the OBS has been accelerated.

== QEMU armel image ==

An Ubuntu armel image for QEMU is available from here: 
http://gitorious.org/mer-toggles/qemu-armel-image (login: qemu/qemu)
 
Based on these instructions: 
https://wiki.ubuntu.com/ARM/RootfsFromScratch

This is NOT a Mer development image like Mer VMDK is.

== Mer Source ==
Currently you cannot <code>apt-get source</code> for Mer.

Our approach requires you to get a Novell account and is similar to the one in HHGTTG:

<blockquote>
"`...You hadn't exactly gone out of your way to call attention to them had you? I mean like actually telling anyone or anything.' 
`But the plans were on display...' 
`On display? I eventually had to go down to the cellar to find them.' 
`That's the display department.' 
`With a torch.' 
`Ah, well the lights had probably gone.' 
`So had the stairs.' 
`But look you found the notice didn't you?' 
`Yes,' said Arthur, `yes I did. It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying "Beware of The Leopard".'"
</blockquote>
 
But slightly simpler...

Nb... the fix is trivial and simply requires you to modify the GPL licensed OBS system to publish debian style source distros ... patches accepted.

 ==Getting Started==
-Approaching OBS can look overwhelming... but it is perfectly possible to get an existing package built for Mer just using a web browser.
