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?
I would suggest you to switch to GCC 9.2 Arm toolchain for Dunfell. RPB does the same [1].
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?
GCCVERSION = "arm-9.2"

Thanks for the pointer.

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