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.

-
== Installing OBS tools locally ==
+
==Getting Started==
-
You'll need an [https://secure-www.novell.com/selfreg/jsp/createOpenSuseAccount.jsp?target=http://www.opensuse.org account with Novell]
+
Approaching OBS can look overwhelming... but it is perfectly possible to get an existing package built for Mer just using a web browser.
-
=== Debian ===
+
The first thing to do is to [[/Install OBS|install OBS]]. This will provide access to the tools and source used to build Mer.
-
Assuming a Debian Lenny/5.0 development box locally:
+
-
To get the OBS tools repository add the following line:
+
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.
-
deb <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /</nowiki>
+
-
to a new file called:
+
-
/etc/apt/sources.list.d/obs.list
+
-
Then
 
-
apt-get update
 
-
apt-get install osc build qemu
 
-
=== Ubuntu ===
+
==Mer Internals==
-
Assuming an Ubuntu9.04 development box locally:
+
-
To get the OBS tools repository add the following line:
+
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.
-
deb <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/xUbuntu_9.04/ /</nowiki>
+
-
to a new file called:
+
-
/etc/apt/sources.list.d/obs.list
+
-
Then
+
There are [[/Processes|processes]] used to manage the Mer packages which may include [[/UsingGitorious|Using Gitorious]].
-
apt-get update
+
-
apt-get install osc build
+
-
Now edit <code>/etc/apt/sources.list.d/obs.list</code> and comment that line out.
+
The OBS [[/Cross Build|cross build]] page describes how the OBS has been accelerated.
-
 
+
-
Note there is a problem in Ubuntu9.04 osc as of 25 May '09... to fix it, do this as root:
+
-
  cd /usr/lib/python2.6/dist-packages/
+
-
  ln -s ../site-packages/osc* .
+
-
 
+
-
Ubuntu qemu isn't up to it so we need the Debian one:
+
-
 
+
-
Add the following lines:
+
-
deb <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /</nowiki>
+
-
deb <nowiki>http://ftp.debian.org/debian/</nowiki> stable main
+
-
to a new file called:
+
-
/etc/apt/sources.list.d/debian5_qemu.list
+
-
 
+
-
Then
+
-
apt-get update
+
-
apt-get install qemu
+
-
 
+
-
 
+
-
Now, as a normal user, run
+
-
osc
+
-
and enter novell.com username/passwd when prompted (note these are stored in cleartext in the config file). Note this isn't supposed to do anything (it prints out the osc help) but it stores your name/pw for future use.
+
-
 
+
-
Go and [https://build.opensuse.org login].
+
-
 
+
-
Make sure you click the "let me build packages" button.
+
-
 
+
-
There is a link to 'Home Project' on the left, follow this and enter a description.
+
-
 
+
-
=== Local osc setup ===
+
-
Create a local build path.
+
-
 
+
-
mkdir -p ~/maemo/Mer/obs
+
-
 
+
-
All references below with (yourusername) should of course be replaced with the login name on your local machine.
+
-
 
+
-
You can now check some settings in your ~/.oscrc :
+
-
 
+
-
This is the OBS builder we're using... maybe we'll use a maemo.org instance one day?
+
-
apiurl = <nowiki>https://api.opensuse.org</nowiki>
+
-
 
+
-
This specifies where all the cached binary packages are held to create a chroot build environment. Around 300MB.
+
-
packagecachedir = /home/(yourusername)/maemo/Mer/obs/.pkg-cache/
+
-
 
+
-
This specifies the default location where a complete chroot build will be installed. This will be a minimal OS install - allow 400MB minimum.  Replace (yourusername) with your current login name
+
-
build-root = /home/(yourusername)/maemo/Mer/obs/build-%(repo)s-%(arch)s
+
-
 
+
-
The next section is credentials for access control to the builder.
+
-
<nowiki>[https://api.opensuse.org]</nowiki>
+
-
user = <username>
+
-
pass = <password>
+
-
 
+
-
== Getting Mer and Packages ==
+
-
 
+
-
Create and cd to a directory to act as the root for the OBS/Mer repository. You'll need space to have a copy of various Mer source packages - around 650MB
+
-
 
+
-
cd ~/maemo/Mer/obs
+
-
 
+
-
Now <code>osc ls Maemo:Mer:Devel</code> will list all the packages.
+
-
 
+
-
If you want the ''entire'' Mer project then you can run <code>osc co Maemo:Mer:Devel</code> to checkout the entire project as tar.gz and .dsc files, or to get just one package <code>osc co Maemo:Mer:Devel/''<package>''</code>
+
-
 
+
-
Errors indicating "HTTP Unauthorized" may indicate account or password issues.
+
-
 
+
-
== Building a package locally ==
+
-
 
+
-
(Note: if you have Scratchbox then you may need to see the section below on temporarily disabling it)
+
-
 
+
-
To work on a package go to the right location and get the source.
+
-
osc co Maemo:Mer:Devel/maemopad
+
-
cd Maemo:Mer:Devel/maemopad        # ie <osc project dir>
+
-
osc up
+
-
osc build --clean Ubuntu_9.04    armv5el maemopad*.dsc        # ie <project.dsc>
+
-
 
+
-
This will download all the (arm) debs to create a local chroot - it'll take a while the first time but will use a cache after that.
+
-
 
+
-
Eventually it will prompt you for the root passwd in order to chroot etc. After that the builder will su to the "abuild" user (uid:gid 399:399) and build the code.
+
-
 
+
-
If you like you can work inside qemu chroot:
+
-
chroot /home/(yourusername)/maemo/Mer/obs/build-standard-armv5el su abuild                # this is the dir you set in .oscrc as the build-root.
+
-
cd /usr/src/packages/BUILD
+
-
 
+
-
at this point:
+
-
./configure
+
-
make
+
-
etc... all work using the binfmt_misc redirection.
+
-
 
+
-
== To create a new package ==
+
-
 
+
-
These osc commands are done in your own area - use your username after "home:"
+
-
 
+
-
Run
+
-
osc meta pkg -e home:<username> <package>
+
-
This pops up an editor where you can edit the name/description and then save.
+
-
This will tell the OBS server about the package.
+
-
 
+
-
To get a local (empty) copy run
+
-
osc up
+
-
This makes a package directory so now you can:
+
-
cp package.tar.gz package.dsc homt:lbt/package
+
-
cd package
+
-
Then add them to version control
+
-
osc addremove
+
-
and upload them
+
-
osc commit
+
-
 
+
-
To watch what is going on:
+
-
osc buildlog <target>
+
-
so
+
-
osc buildlog Debian_5.0 i586
+
-
 
+
-
This does something like a "tail -f" of the Xen builder.
+
-
 
+
-
=== Standalone Project ===
+
-
 
+
-
On the web, create the (sub)project maemopad.
+
-
 
+
-
In the repository section add a repository and from advanced select the Mer project: Maemo:Mer:Devel
+
-
 
+
-
Now we need to pick build targets:
+
-
  <nowiki>https://build.opensuse.org/project/add_target_simple?project=home:<username></nowiki>
+
-
 
+
-
And pick one or two ( I picked Debian Lenny and Ubuntu 8.10)
+
-
This creates a standalone project and builds against another project
+
-
 
+
-
Goto your obs base (eg /scratch3/maemo/Mer/obs) and checkout the project:
+
-
  osc co home:<username>:maemopad
+
-
 
+
-
Now create the package metadata:
+
-
  osc meta pkg -e home:<username>:maemopad maemopad
+
-
 
+
-
and get a local copy (empty still):
+
-
  cd home:<username>:maemopad/
+
-
  osc up
+
-
 
+
-
the 'osc up' created a directory so go into it and get the source:
+
-
  cd maemopad/
+
-
  wget <nowiki>http://repository.maemo.org/pool/maemo4.1.2/free/m/maemopad/maemopad_2.4.dsc</nowiki>
+
-
  wget <nowiki>http://repository.maemo.org/pool/maemo4.1.2/free/m/maemopad/maemopad_2.4.tar.gz</nowiki>
+
-
 
+
-
Use the cheap'n'cheerful 'register all file adds and removes with vc'-command:
+
-
  osc addremove
+
-
 
+
-
and then commit the source which uploads it to the OBS
+
-
  osc commit -m "added source"
+
-
 
+
-
This will trigger a rebuild and you can access the logs.
+
-
 
+
-
== Co-existing with Scratchbox ==
+
-
 
+
-
If you use the OBS local build facility and the scratchbox-1 local builder then you need to know how to teach the two emulators how to co-exist.
+
-
 
+
-
Both OBS and Scratchbox use [http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/binfmt_misc.txt;hb=HEAD binfmt_misc] to cause the kernel to invoke (in our case) qemu when it comes across an armel binary.
+
-
 
+
-
To disable qemu and enable sbox
+
-
  echo 0 > /proc/sys/fs/binfmt_misc/arm
+
-
  echo 0 > /proc/sys/fs/binfmt_misc/armeb
+
-
  echo 1 > /proc/sys/fs/binfmt_misc/sbox-arm
+
-
  echo 1 > /proc/sys/fs/binfmt_misc/sbox-armeb
+
-
 
+
-
To disable sbox and enable arm
+
-
  echo 1 > /proc/sys/fs/binfmt_misc/arm
+
-
  echo 1 > /proc/sys/fs/binfmt_misc/armeb
+
-
  echo 0 > /proc/sys/fs/binfmt_misc/sbox-arm
+
-
  echo 0 > /proc/sys/fs/binfmt_misc/sbox-armeb
+
-
 
+
-
Don't do this whilst a build is in progress!
+
-
 
+
-
Note that you may need to run :
+
-
  qemu-binfmt-conf.sh
+
-
to register qemu to handle arm binaries
+
-
 
+
-
== Linking ==
+
-
 
+
-
To link to a source create a _link file containing:
+
-
  <link project="linked project name" package="linked package name">
+
-
 
+
-
optionally:
+
-
  <patches>
+
-
    <apply name="name of the first patch" />
+
-
  </patches>
+
-
 
+
-
Sadly these patches apply to the files in the source; so this means you need to apply the diff to the maemo-ised diff file.

== OBS Project structure and promotion ==
 
-
 
-
The Mer projects on OBS look like this:
 
-
Maemo:Mer:Stable
 
-
Maemo:Mer:Stable:HW:Beagle
 
-
Maemo:Mer:Stable:HW:N8x0
 
-
 
-
This means all devices will have the main 'Stable' repository and an appropriate HW repository.
 
-
 
-
The development area is expanded slightly:
 
-
Maemo:Mer:Devel:Apps
 
-
Maemo:Mer:Devel:Base
 
-
Maemo:Mer:Devel:MaemoCommon
 
-
Maemo:Mer:Devel:MaemoCommon:L10n
 
-
Maemo:Mer:Devel:UI
 
-
Maemo:Mer:Devel:HW:Beagle:Devel
 
-
Maemo:Mer:Devel:HW:N8x0:Devel
 
-
 
-
Packages in each of these Devel subproject areas can be hacked on and then, when they're kinda working they are consolidated into the :Devel area (which is used as a build target for the :Devel:* subprojects)
 
-
Maemo:Mer:Devel
 
-
Maemo:Mer:Devel:HW:N8x0
 
-
Maemo:Mer:Devel:HW:Beagle
 
-
 
-
Packages are placed in :Testing with the intention of including
 
-
them in the next release subject to QA and bug fixes
 
-
 
-
  Maemo:Mer:Testing
 
-
  Maemo:Mer:Testing:HW:Beagle
 
-
  Maemo:Mer:Testing:HW:N8x0
 
-
 
-
Once :Testing is ready a release of all packages to a numbered version is made:
 
-
  Maemo:Mer:0.13
 
-
  Maemo:Mer:0.13:HW:Beagle
 
-
  Maemo:Mer:0.13:HW:N8x0
 
-
 
-
Note that the :HW promotion process is slightly different:
 
-
Maemo:Mer:Devel:HW:N8x0:Devel -> Maemo:Mer:Devel:HW:N8x0 -> Maemo:Mer:Testing:HW:N8x0 -> Maemo:Mer:Stable:HW:N8x0

=== Promotion Tasks ===
 
-
 
-
To promote a package:
 
-
  osc copypac <SOURCEPRJ> <SOURCEPAC> <DESTPRJ>
 
-
eg:
 
-
  osc copypac Maemo:Mer:Devel glib2.02 Maemo:Mer:Testing
 
-
 
-
Ensure that:
 
-
  osc meta prjconf <SOURCE>
 
-
is copied to the <TARGET> conf. This may contain things like package selection preferences.
 
-
Currently the prjconf is:
 
-
  Prefer: hildon-fm-l10n-mr0
 
-
  Ignore: hildon-fm-l10n-mr
 
-
 
-
== To Promote :Devel To :Testing ==
 
-
 
-
First pipe over the project metadata:
 
-
  osc meta prjconf Maemo:Mer:Devel  | osc meta prjconf Maemo:Mer:Testing -F -
 
-
 
-
Then run:
 
-
  for i in $(osc ls Maemo:Mer:Devel); do echo $i; osc copypac Maemo:Mer:Devel $i Maemo:Mer:Testing ; done
 
-
  for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
 
-
    for i in $(osc ls Maemo:Mer:Devel:$HW); do echo $i; osc copypac Maemo:Mer:Devel:$HW $i Maemo:Mer:Testing:$HW ; done
 
-
  done
 
-
 
-
== To Promote :Testing to :Stable ==
 
-
 
-
The process here is to create a versioned repo; eg :0.13
 
-
 
-
  export STABLE=0.13
 
-
First pipe over the project metadata:
+
== QEMU armel image ==
-
  osc meta prjconf Maemo:Mer:Testing  | osc meta prjconf Maemo:Mer:$STABLE -F -
+
-
Then run:
+
An Ubuntu armel image for QEMU is available from here:<br>
-
  for i in $(osc ls Maemo:Mer:Testing); do echo $i; osc copypac Maemo:Mer:Testing $i Maemo:Mer:$STABLE ; done
+
http://gitorious.org/mer-toggles/qemu-armel-image (login: qemu/qemu)
-
  for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
+
<br>
-
  for i in $(osc ls Maemo:Mer:Testing:$HW); do echo $i; osc copypac Maemo:Mer:Testing:$HW $i Maemo:Mer:$STABLE:$HW ; done
+
Based on these instructions:<br>
-
  done
+
https://wiki.ubuntu.com/ARM/RootfsFromScratch<br>
-
Then, once it's built and stable, use _aggregate to link each package to :Stable

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

First clean out :Stable

== Mer Source ==
-
  for i in $(osc ls Maemo:Mer:Stable); do osc deletepac Maemo:Mer:Stable $i ; done
+
Currently you cannot <code>apt-get source</code> for Mer.

  for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
+
-
    for i in $(osc ls Maemo:Mer:Stable:$HW); do echo $i; osc deletepac Maemo:Mer:Stable:$HW $i; done
+
-
  done
+
-
  for i in $(osc ls Maemo:Mer:$STABLE); do osc aggregatepac Maemo:Mer:$STABLE $i Maemo:Mer:Stable; done
+
Our approach requires you to get a Novell account and is similar to the one in HHGTTG:
-
  for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
+
-
    for i in $(osc ls Maemo:Mer:$STABLE:$HW); do echo $i; osc aggregatepac Maemo:Mer:$STABLE:$HW $i Maemo:Mer:Stable:$HW; done
+
-
  done
+
-
Note that :Stable project must be setup to publish and to build

 Mer is back : Please visit http://www.merproject.org to learn more about this news.


This section documents how to use the openSUSE Build Service with Mer. More on the openSUSE Buildservice 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).

[edit] 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.

The first thing to do is to 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 which takes you through an example application.


[edit] Mer Internals

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

There are processes used to manage the Mer packages which may include Using Gitorious.

The OBS cross build page describes how the OBS has been accelerated.

[edit] 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.

[edit] Mer Source

Currently you cannot apt-get source for Mer.

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

"`...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".'"


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.
