[Buildroot] via_imx6_vab820_defconfig fails to build

[Thomas Petazzoni]

Hello Gergely,

Last year, you contributed the via_imx6_vab820_defconfig to Buildroot
to add support for this HW platform from VIA.

Unfortunately, this defconfig no longer builds, because the U-Boot
version used is too old to build with gcc 5.x.

If you still have access to this HW platform, could you submit a patch
that updates the defconfig to use a newer U-Boot version, which
builds properly with gcc 5.x ?

See
http://free-electrons.com/~thomas/pub/buildroot-defconfigs/via_imx6_vab820_defconfig.log.FAIL
for the full build log.

Thanks a lot!

Thomas

Hi Thomas,

Sure thing, I still have some access to the platform. I'll check out the
build failure and send a patch when fixed.

Cheers,
   Gergely

Any news on this? You need to move to kernel 3.18+ for compatibility
with gcc5.x or alternatively backport this commit (and any
dependencies):


commit 71458cfc782eafe4b27656e078d379a34e472adf

    kernel: add support for gcc 5

    We're missing include/linux/compiler-gcc5.h which is required now
    because gcc branched off to v5 in trunk.

    Just copy the relevant bits out of include/linux/compiler-gcc4.h,
    no new code is added as of now.

    This fixes a build error when using gcc 5.

Do you think you will manage to fix the build issue before the end of
January or should we remove the defconfig?
