please fix build failures, including those introduced by GCC 5

by Matthias Klose

Hi, two test rebuilds for vivid are almost finished on all architectures (pending powerpc and arm64). It's time to address the build failures seen with these test rebuilds. The most important ones are listed in [1] for the vivid archives. These really have to be addressed. In preparation for the w-series (15.10), there was another test rebuild using GCC 5 (yes, GCC 5 will be the default for 15.10, without any possibility to fall back to older g++ and gfortran versions). Some outfall as usual [2]. I think the switch to GCC 5 will cause a bit more work than the switch to GCC 4.9 in utopic, so I would like to address as many issues as possible before the switch, even during the preparation of the 15.04 (vivid) release. Safe uploads to vivid would be appreciated. To check for buildability with GCC 5, add the ubuntu-toolchain-r/test PPA [3] to your apt sources. If you have time to kill, please fix these issues now. Make sure to forward fixes to the Debian bug tracker, bugs were filed for a Debian test rebuild as well [4]. Help for porting issues can be found in the GCC 5 porting notes [5] and an analysis of a test rebuild for another distro [6]. If you can't, or if you don't want to do an upload, please make sure to file a launchpad issue, and tag it with 'ftbfs' and probably 'patch', then the issue will show up in [1] and [2]. Help would be appreciated to fix issues in packages like boost so that we can get more reliable test rebuild results.

== Progress == * CARD-788 "EPIC: Linux linaro baseline maintenance" (5%): - linux-linaro schedule for 15.03 published on the wiki - tried moving llct to v4.0-rc1: 15 conflicts when merging the android topic. They seem to be not hard to resolve though. * CARD-1161 "Add ILP32 support for ARM64 to Linaro engineering builds" (75%): - added submission to LAVA to my existing ILP32 build job (Juno; both ILP32 and LP64 variants). Prepared the card for close-out. The remaining issues will be resolved under card DEVPLAT-321 "clean up ILP32 build job" * local holiday on Feb 23 (20%) == Plans == * CARD-788 "EPIC: Linux linaro baseline maintenance": - update linux-linaro to v4.0-rc2 * DEVPLAT-321 "clean up ILP32 build job" == Issues == * none

Updated Fastmodels available for Linaro employees/assignees

by Ryan Harkin

Hello Linaro employees/assignees, I've updated the Fastmodels binaries available for Linaro use. Visit the ITS page [3] for more details on filenames etc. for the download. FVP Base models are now at version/build 0.8.6302 from 18th Feb 2015. FVP Foundation and FVP VE models are now at build 9.2.28 from 20th Feb 2015. A couple of points worth noting as it broke my scripts at least: - The CPU configurations available with the FVP Base Cortex A57/A53 Model [1] is 1+1 or 2+4, previously it was 1+1 or 4+4. - The FVP Foundation [2] model's executable filename has changed from Foundation_v8 to Foundation_platform. We in ARMLT only use/test with the FVP Base and FVP Foundation models, so using FVP VE models is generally out of scope for our support. I successfully booted out 15.02 OpenEmbedded release with the FVP Base and Foundation models. Please contact support(a)linaro.org in the first instance if you encounter any problems. Regards, Ryan.

== Progress == DEVPLAT-271 luvOS CI loop - pushed first draft of luvOS.yaml DEVPLAT-289 CI bringup: A80 Optimus board - coordinated with LHG (Will and Zhenhua) to get an image to the LAVA team - my download of the 53GB of sources has finally completed (it takes about a week for me to pull that much through my 3MB DSL connection) DEVPLAY-319 OpenEmbedded: enable buildhistory - studied the OE buildhistory.class and found two nice ways of integrating buildhistory with our builds (BUILDHISTORY_PUSH_REPO and BUILDHISTORY_DIR) - was reminded of NicolasD's script from the RDK project == Plans == - verify the luvOS build and push artifacts to snapshots - perform a local build of Android for the A80 board (and take note of where the instructions diverge from the reality) - take an existing OE build and add NicolasD's buildhistory script to it == Issues == - my local build of luvOS is failing in meta-luv/recipes-core/fwts/ fwts_git.bb (a week ago my luvOS build was succeeding)
