Hi At Linaro we are working on cross toolchain for ARM/EABI target (known as 'armel' in Debian and Ubuntu based systems). We base on work made by Debian and Ubuntu toolchain maintainers. Latest version of cross toolchains are available in prebuilt form on: http://people.canonical.com/~hrw/ubuntu-maverick-armel-cross-compilers/ I provide there gcc-4.4, gcc-4.5, binutils and eglibc packages. Use them, report bugs to Ubuntu launchpad. Regards, -- JID: hrw(a)jabber.org Website: http://marcin.juszkiewicz.com.pl/ LinkedIn: http://www.linkedin.com/in/marcinjuszkiewicz

[Linaro-dev] Python2.5 compatibilty requirement for the Infrastructure Team

by Zygmunt Bazyli Krynicki

Hello everyone. Our current developer guidelines for python development state that we should support both python2.5 and python2.6. I'd like to ask if python2.5 can be dropped from the list. I just took the steps required to test python2.5 (and removed 2.6-only features in the process). I had to use Hardy VM to do so because python 2.5 is no longer available in the Lucid archive. Doing additional testing in a VM is cumbersome and error-prone as we can accidentally slip in a 2.6-only code or trigger 2.5 bug we didn't know about and it might go untested. Can we rationalise the requirements for supporting python2.5 and if so, devise a sensible testing plan for our python development? BTW: It's worth publishing our python development practices on the Linaro wiki. Best regards Zygmunt

[Linaro-dev] Integrating Debian/Ubuntu GCC Patch Set in Ubuntu

by Andrew Stubbs

Hi All, Matthias and I have been throught the Ubuntu GCC 4.4 patch set and decided what to do with each of them in Linaro GCC 4.4 and 4.5. Some patches will be integrated into Linaro, and some will remain Debian/Ubuntu local.

[Linaro-dev] Rebuild of Ubuntu main with initial gcc-4.4 Linaro patch

by Loïc Minier

Hi Wanted to share that Matthias Klose launched a rebuild of Ubuntu main packages on i386 and amd64 with gcc-4.4 + first Linaro diff which we had sent him. All build failures: https://launchpad.net/ubuntu/+archive/test-rebuild-20100628/+builds?build_t… What needs to happen is reviewing the failures to see whether they are regressions caused by the Linaro diff. One way to do that is to compare with: http://udd.debian.org/cgi-bin/ubuntu_ftbfs.cgi which has failures from a recent rebuilds of Ubuntu (compare the version number as well!). Steve Langasek told me the Foundations team might be able to help sort these into toolchain and non-toolchain bugs. For each build failure: Check whether it's a regression with the same source + version If it's a regression: If it's a toolchain bug: file a bug against gcc-linaro Else: file a bug against the Ubuntu package, tag it gcc-linaro Else: decide whether it's worth filing a bug against the Ubuntu package Thanks! -- Loïc Minier

[Linaro-dev] Embedded Qt (QWS) packages

by Alexandros Frantzis

Hi all! As part of the User Platform team's exploration of non X11-based graphical environments I have started experimenting with the QWS variant of the Qt library (also known as Qt/Embedded). Qt/QWS offers the ability to render graphics directly on a Linux framebuffer without the need for X11 or any other windowing system. It provides its own simple windowing system, which is (unsurprisingly) called the Qt Windowing System (QWS). The Qt/QWS variant is mostly API compatible with Qt/X11, except for some X11 specific functions and some missing libraries (eg QtOpenGL). Most Qt programs should build without problems with Qt/QWS. Note, however, that Qt/QWS is *not* ABI compatible with Qt/X11. Qt/QWS has been tested successfully on the x86 architecture under both X11 (using the QVFB virtual framebuffer) and the Linux framebuffer. Tests for the ARM architecture are under way. If you test the libraries on ARM please let us know how it went! You can find installation and usage instructions at: https://wiki.ubuntu.com/Specs/M/ARMQtonEmbedded/Guide You can also find some screenshots at: http://people.canonical.com/~afrantzis/qt4-qws-screenshots/ If you have any issues or questions don't hesitate to contact me! As a side note, the next generation of Embedded Qt, called (for now) project Lighthouse, is planned for Q1 2011 and is going to improve on QWS by offering support for hardware acceleration and a plugin architecture for windowing systems (instead of just a built-in one). We are keeping an eye on that and are planning to eventually provide experimental packages for Lighthouse. Thanks, Alexandros

[Linaro-dev] Contributing in development.

by pankaj chauhan

All, I joined few days back with intention to contribute in development. I have experience in device drivers and base port for Arm based SOCs. But i am not sure where to start here in lenaro! I have access to A9 dual core based boards at work, and if necessary i'll arrange beagle board. Are we going to have some formal start of project emails on the list? how would i know which areas require contribution from volunteers? Thanks and regards, pankaj

[Linaro-dev] ALSA SoC device tree bindings

by Jeremy Kerr

Hi all, From some discussions at the previous Ubuntu Developer Summit, I've put up a page on the devicetree.org wiki with the ultimate goal of describing device tree bindings for ALSA System on Chip devices. At this stage, we're just looking at how to structure device in the device tree. The bindings for specific devices will come as required (ie, as we add device tree support for them). So - if you're interested in the ALSA and/or device tree areas, please take a look at the notes from UDS: http://devicetree.org/SoC_Audio - if you have any comments or suggestions, please let me know, or add to the page (or the discussion for the page). I intend for this document to become a more formal specification, but we still have a way to go before that happens. If you'd like an introduction to device trees, Grant has a good walkthrough- style document at: http://devicetree.org/Device_Tree_Usage Cheers, Jeremy
