Hi, the toolchain WG is officially releasing a 4.7 based compiler this month - and I'd like it to become the default, let's stay ahead of the line. We know the userland is fine since we have working iMX6 and Panda builds done with 4.7. I've created gcc47 builds for every board (simply replace gcc46 with gcc47 in the name). The following builds failed in the initial run: ~linaro-android/imx53-ics-gcc47-freescalelt-stable-open ~linaro-android/snowball-ics-gcc47-igloo-tracking-blob ~linaro-android/vexpress-ics-gcc47-armlt-stable-open ~linaro-android/panda-ics-gcc47-kwg-upstream-open ~linaro-android/panda-ics-gcc47-omapzoom-stable-blob ~linaro-android/panda-ics-gcc47-tilt-stable-blob ~linaro-android/origen-ics-gcc47-samsunglt-tracking-blob Most of the failures look like random linaro-build breakage ("hudson.util.IOException2: remote file operation failed: /mnt/jenkins/workspace/linaro-android_imx53-ics-gcc47-freescalelt-stable-open at hudson.remoting.Channel@1150f8c:i-2468d843"), so we're actually better than it looks. ;) I'm restarting the failed builds - hopefully we'll have some more working builds in the evening and useful error messages for the ones that keep failing (there were a couple of initial failures (fixed by now) in the iMX6 and Origen kernels - expecting to see some more of those, but they should be easily fixable. ttyl bero

DisableSuspend is now in builds

by Zach Pfeffer

Heads up, DisableSuspend, the handy little utility to keep a build on, is now coming out on tips. Its on https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc46-til… and should be in other builds as android-build rebuilds them.

Linaro embedded Linux distro?

by Zach Pfeffer

During ELC a few people asked me if Linaro had something bigger than nano and smaller than Ubuntu that they could use to build stuff. Of course I said Android, but a lot of people actually want a regular Linux platform where they can easily recompile what they need to hack on, add their own libs and scripts and generally work in an "embedded, cross build way." I know there's OpenEmbedded and I've heard of something called "livebuild." Does anyone have anymore info? This class of users is arguably the largest class of people using these boards so creating something targeted at them would allow them to get all the benefits of Linaro in a easy to use fashion. -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

$TARGET_TOOL_PREFIX

by Mathieu Poirier

Friends of the greed robot, The attached file is used to compile the MM libs from one of our vendor. On line 224 the variable TARGET_CROSS_COMPILE is assigned the value 'arm-eabi-', forcing the build script to look in $PATH for the compiler. This is obviously not what we want. I commented out 218 and added 219 and the libs are now compiled with 'arm-linux-androideabi-'. I would like to know if there is a better way to fetch the linaro-android toolchain or if it is ok to simply reference TARGET_TOOL_PREFIX the way I did. Regards, Mathieu.

can someone help with linker error on panda tilt build 255 kernel - Ask Linaro

by Michael Opdenacker

Hi List, You may be able to answer this question on Ask Linaro: http://ask.linaro.org/questions/1063/can-someone-help-with-linker-error-on-… The guy is getting compile warnings: arm-eabi-ld: warning: unwinding may not work because EXIDX input section 8 of arch/arm/nwfpe/built-in.o is not in EXIDX output section And his kernel doesn't seem to boot (though it could be a mistake on the user's side). Cheers, Michael. -- Michael Opdenacker - Community tech support Linaro, http://linaro.org Phone: +33 484 253 396 IRC: 'opm' in #linaro on irc.freenode.net

Re: Creating a branch in Android

by Zach Pfeffer

Yeah, that should be okay. Though we could do it using a separate branch. That may make ongoing maintenance easier. We can name the branch: linaro_android_4.0.4_origen Will that work?
