dunfell gcc-sanitizers-arm-8.3 fails to build

[Ryan Harkin]

[-- Attachment #1: Type: text/plain, Size: 1279 bytes --]

Hello,

I'm migrating from Warrior to Dunfell and I'm getting a curious build
failure in gcc-sanitizers.

Here's the full gory detail:
    https://pastebin.ubuntu.com/p/nh4cDKMvgS/

However, the main error is this:

| In file included from
../../../../../../../../../work-shared/gcc-arm-8.3-r2019.03/git/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:193:
|
../../../../../../../../../work-shared/gcc-arm-8.3-r2019.03/git/libsanitizer/sanitizer_common/sanitizer_internal_defs.h:317:72:
error: size of array 'assertion_failed__1152' is negative
|      typedef char IMPL_PASTE(assertion_failed_##_, line)[2*(int)(pred)-1]

I have no idea where to begin with this. I don't even know why
gcc-sanitizers is included in the build, what it does, or why I need it.
I'm building an image with dev packages and gcc, so I guess that's why.

I've hacked meta-arm to patch sanitizer_platform_limits_posix.cc to null
out the macros and that builds fine. I'm sure it won't work, should someone
want to use it, mind you.

Is there something obvious that I should be doing as part of a Warrior ->
Dunfell migration to get this to work?

note: Warrior used meta-linaro-toolchain and for Dunfell, it's moved to
meta-arm-toolchain.

Regards,
Ryan.

I would suggest you to switch to GCC 9.2 Arm toolchain for Dunfell.
RPB does the same [1].

GCCVERSION = "arm-9.2"

I assume so. I haven't attempted to change the default.

I can do that, I have no reason to use 8.3 other than it's the default. Is
my problem a known issue with 8.3, or is moving to 9.2 a general suggestion?

I'm sorry, that's incorrect: local.conf has an over-ride to specify 8.3.
I've just removed it and now it's using 9.3. And it's building fine.

Sumit, do you know if there's a reason for using 9.2 in RPB instead of 9.3?

AFAIK, as upstream OE switches to a newer GCC version, it stops
supporting older GCC versions. And since we are building here Arm
toolchain from source and rely on OE core recipes, so it is possible
that build could fail while trying to build an old toolchain version
using latest OE core recipes.

So the general recommendation is to keep the Arm toolchain version as
close to the OE core to avoid any possible build failures.

Arm GCC 9.3 toolchain isn't released yet (see here [1]).

It's using GCC 9.3 from OE core. If you wish to use Arm toolchain then
you need to override the default OE core GCC version with Arm
toolchain GCC version:

GCCVERSION = "arm-9.2"

Ah, right, I see! Yes, I think I'll stick with that suggestion.
