Hi,

Thanks for reporting thi=

The error indicates that the linker is unable to locate libm.so.6 and
libmvec.so.6 in the recipe sysroot.
These libraries are normally provided by glibc, and this issue does not
appear to be caused by our patches, as we are not able to reproduce it
locally.
Could you please re-test the series once more to confirm?

Thanks,
Harish

Ok, thanks for testing again on your side. It may have been related to an=
other
commit on my branch as I'm not facing the issues again. I'll re-add the s=
eries
to my branch - sorry for the false alarm!

Sorry, but after starting an a-full run with your series again, I started
getting the same errors again:

https://autobuilder.yoctoproje=
ct.org/valkyrie/#/builders/29/builds/3110

I've launched an a-full build with the same branches minus your series an=
d I
don't see the errors anymore:

https://autobuilder.yoctoproje=
ct.org/valkyrie/#/builders/29/builds/3115

You can compare the branches used for the two builds by comparing:

https://git.yoctoproject.org/poky-ci-archive/log/?h=3Doecore/aut=
obuilder.yoctoproject.org/valkyrie/a-full-3110

https://git.yoctoproject.org/poky-ci-archive/log/?h=3Dmeta-y=
octo/autobuilder.yoctoproject.org/valkyrie/a-full-3110

vs.

Maybe your build uses some shared state which is why your builds pass?

You can base off your test builds against my a-full-3110 branches above, =
that
may help.
I was able to reproduce the issue locally.

Failure was happening due to Alistair Francis's patch from my v4 series (https://lists.openembedded.org/g/openembedded-core/message/229769= ) when applied together
with following patch "llvm: enable LLVMgold.so build by addi= ng binutils dependency(https://lists.openembedded.org/g/openembedded-core/message/229= 387)"

To avoid this issue, I am dropping Alistair Francis=E2=80=99s pa= tch (https://lists.openembedded.org/g/openembed= ded-core/message/229769) from my patch set.
We will send a v5 series tomorrow.

Thanks,
Harish

Antonin
