Build maemo-apps with openSUSE BuildService ? – It works !

January 27th, 2009 by

build serviceThe openSUSE Build Service is an open and complete distribution development platform. It’s the infrastructure for a development of the openSUSE distributions. But this powerful tool can do much more! The upcoming version 1.5 will also have cross-build support and thus be able to build e.g. ARM packages on x86 hardware .

maemo.org loko Maemo is the platform for mobile devices like the N810 and has been developed by Nokia in collaboration with many open source projects such as the Linux kernel, GNOME and many more. (more…)

ARM support for openSUSE Buildservice and openSUSE

November 18th, 2008 by

ARM architecture going more to desktop style applications had been in press frequently during the last weeks. On top of were press releases of ARM and canonical officially announcing an ubuntu port in one of the next releases for the ARM architecture. Applications are more of type nettop or advanced PDA like the nokia n810, than what is currently known as traditional embedded applications (just to name a few examples).

This has been due to the fact that licensees of the ARM architecture, big semiconductor companies from the Top 10 list, have begun shipping a new generation of “mobile PC in the pocket” of System on a Chip semiconductors. They include now a really high clocked ARM core, DSPs for Video/Audio processing that can even decode HDTV streams, and OpenGL 2.0 capable HW engine and the peripherials included to build PDAs, mobile phones or nettops. All that within the energy budget of a mobile phone, and not of a Desktop PC. The google G1 phone had been one of the first products of this generation, although its software uses these features only in the beginnings.

What now does this all have to do with the openSUSE Buildservice and openSUSE distribution? As you might already guess it, we haven’t been sleeping either. And I am not a advocate of ubuntu on an .opensuse.org website. So read further what we have done so far.

openSUSE Buildservice: cross-build

October 4th, 2008 by

There is some good news for you: in cooperation with Marcus Hüwe the download on demand feature is now working seamlessly with cross-build, making it a combined “super feature”.

Also, I have put together a “condensed” cross-build in OBS document in the OBS Wiki Concepts collection.

New OBS cross-build installation packages will be provided inside openSUSE:Tools:Devel soon.

Have fun.

openSUSE Buildservice: cross-build with OBS Part 3

Hackweek Day 3: cross-build with OBS Part 2

September 1st, 2008 by

This is the second part of my article series about the Hackweek Project “cross-build in the OBS”. The first part can be found here.

Before I come back to our Hackweek project, some information about the qemu emulator. As a preparation to Hackweek, I talked with Uli Hecht and Jan Kiszka. Uli Hecht is the Novell/SUSE Maintainer of the qemu packages in openSUSE:Factory/qemu and maintainer of the OBS project Emulators, where every emulator you can imagine is maintained for a couple of linux distributions. Also I consulted Jan Kiszka, one of the reviewers and maintainers of the qemu upstream project about the status of the qemu in general, “User Mode” and status of important architectures specifily.

Hackweek Day 2: cross-build with OBS Part 1

August 31st, 2008 by

I took the chance to meet with the openSUSE Buildservice Developers on tuesday and discuss with them the progress made so far. Although the OBS was not a theme at Hackweek that much, I found two people participating.

Dirk Müller, Marcus Hüwe and me decided to meet at Hackweek to accelerate the development by adding a way to build for architectures, where the buildhost is different from the architecture you are working at. Dirk was inspired by the call of some KDE akademy participants to get the Maemo Project used in the Nokia N810 building and running in OBS. We were all motivated by all the embedded systems out there and a secenario of running embedded openSUSE on them. Also, Adrian told me very often that cross-build is one of the most wanted features requested when openSUSE and OBS is beeing presented at an event.

openSUSE Gets the JeOS

July 16th, 2008 by

openSUSE is great for the desktop, great for the server, and now it’s ready to take on appliances — and we don’t mean toasters and blenders. No, we’re talking about software appliances — virtual machine images that come pre-configured with the application you want to use, without any of the hassle normally associated with installing an application.

If you’re interested in building a virtual appliance, or have another use for a minimal operating system, read on to learn about openSUSE LimeJeOS.

What is LimeJeOS?

LimeJeOS is the openSUSE version of JeOS. The term JeOS (“Just enough Operating System”) refers to a customized operating system that precisely fits the needs of a particular application. LimeJeOS includes only the pieces of an operating system required to support a particular application and any other third-party components contained in the appliance. This makes the appliance smaller, more efficient, more secure, and offers better performance than an application running under a full, general-purpose operating system.

As the name suggests, “LimeJeOS” itself is not an appliance or an operating system; it is just the base for various possible appliances. LimeJeOS contains just the very basic parts of an operating system. The major goal is to make the system as small as possible while providing the possibility to install additional software. A LimeJeOS system itself is not very useful without additional packages. Besides an editor (a stripped version of vi) it just contains a package manager that allows the actual applications to be installed. Of course all the usual repositories can be used for that purpose; just with a regular, full-size Linux distribution.

What is the difference between SLE JeOS and LimeJeOS?

SUSE Linux Enterprise JeOS relates to LimeJeOS just like openSUSE relates to SLES. In fact, SLE JeOS is built from the latest version of SLES while LimeJeOS is built from the latest version of openSUSE. While LimeJeOS provides the latest state of the openSUSE distribution, SLE JeOS will offer all the services and support that is also available for SLES.

Which one should you use? If you’re working on a virtual appliance for a project that won’t require commercial support, and you want to track the latest in open source, openSUSE is the version for you.

If you’re working on a project that’s likely to need support, then you probably want to go with SUSE Linux Enterprise JeOS.

Where can I get LimeJeOS?

LimeJeOS is built using kiwi. The configuration files are managed via Subversion and are available at: https://forgesvn1.novell.com/svn/opensuse/trunk/distribution/images/LimeJeOS/

In the future we plan to create a regular package (RPM) and add it to the openSUSE build service, so that the latest version is always created automatically with the latest software versions in openSuSE.

How to build LimeJeOS?

Check out the current version of LimeJeOS using the following commands:

svn co https://forgesvn1.novell.com/svn/opensuse/trunk/distribution/images/LimeJeOS

Make sure you have the needed kiwi packages installed. You will need at least: kiwi, kiwi-tools and kiwi-desc-vmxboot and/or kiwi-desc-xenboot from http://download.opensuse.org/repositories/openSUSE:/Tools/. When those conditions are met, building the openJeOS images is accomplished by just running the “./build.sh” script from the LimeJeOS repository.

./build.sh

Please note that the build process will need at least twice as much diskspace as the final images, so you’ll need around 2 GB of free disk space at this time to build Lime JeOS.

After you have booted the virtual system, log in as user “root” with password “linux”.
