We are pleased to announce the release of Linaro 12.03.

Linaro 12.03 contains components delivered by all Linaro Teams –Working Groups, Landing Teams and Platform Teams– and brings an abundance of exciting updates and new features which are integrated on top of Android and Ubuntu. We, together with our members, partners and community continue to build future of Linux on Arm and the 12.03 release is one more step toward that future.

During the 12.03 release cycle, the Linaro Toolchain Working Group announced the 12.03 release of both Linaro GCC 4.6 and Linaro GCC 4.5. Linaro GCC 4.6 12.03 is the thirteenth release in the 4.6 series and is based off the latest GCC 4.6.3 release; it contains a new scheduler pressure pass, implements new instructions, and contains a number of bug fixes. Linaro GCC 4.5 12.03 is the nineteenth release in the 4.5 series and is based off the latest GCC 4.5.3+svn184976 release; this is a maintenance only update. Additionally, the Linaro Toolchain Working Group announced the release of Linaro QEMU 12.03 which is based off upstream (trunk) QEMU, it includes a number of Arm-focused bug fixes and enhancements.

The Linaro Multimedia Working Group during the 12.03 Linaro release cycle added updates to the following: pulseaudio and alsa, initial source code only drop of TinyHal, libav AAC optimization and Speex for Android and Linux.

The Graphics Working Group also announced its contributions to the 12.03 release adding updates and improvements to the following components: glmark2, glcompbench, glproxy, nux and Unity.

Pre-built release images for the Android and Ubuntu LEBs are currenly available with each of the Linaro monthly releases; however, new with the Linaro 12.03 release is that now developers can get daily pre-builds of the Ubuntu LEB which will be based on the current release of Ubuntu. Pre-built images can be found at

“The introduction of prebuilt images for Linaro’s daily output will widen the reach of Linaro’s integrated evaluation builds. One advantage to the availability of these daily builds is that it gives professionals using Windows and MacOSX the opportunity to more easily install these images using the standard tools which are commonly available in these environments”, says Alexander Sack, Technical Director, Linaro Platforms.

Linaro Member Services Program Director, Vicky Janicki, says “Pre-built images save time and effort for our Members and their customers as a starting point for their work. Instead of hunting in different places for code, images, and working out licensing agreements, an engineer simply goes to the Linaro download site knowing all the pieces will work together. The engineer now has access to a current Linux kernel in less than 10 minutes.”

Additional items of interest from the Linaro 12.03 release cycle include:

Registration is now open for the Linaro Connect Q2.12 event being held at the Gold Coast Hotel in Hong Kong from 28 May through 1 June, and brings together some of the best software developers from the Linaro ecosystem to help develop and plan the future of Linux on Arm.

A ‘Call for Submissions’ for Linaro Connect Q2.12 Plenaries was also announced –Do you have a great idea you would like to present to the Linaro Connect Q2.12 attendees? Want to share a Linaro success story and motivate, inspire, excite or educate attendees? Then this is an opportunity for you to get involved in this Linaro Connect event.

The release details are linked from the “Details” column for each released artifact on the release information:

Using the Android-based images

The Android-based images come in three parts: system, userdata and boot. These need to be combined to form a complete Android install. For an explanation of how to do this please see:

If you are interested in getting the source and building these images

yourself please see the following pages:

Using the Ubuntu-based images

The Ubuntu-based images consist of two parts. The first part is a hardware pack, which can be found under the hwpacks directory and contains hardware specific packages (such as the kernel and bootloader). The second part is the rootfs, which is combined with the hardware pack to create a complete image. For more information on how to create an image please see:
