[Buildroot] Buildroot ts7680_defconfig no longer builds

[Thomas Petazzoni]

Hello Julien,

The ts7680_defconfig in Buildroot no longer builds:

  https://gitlab.com/buildroot.org/buildroot/-/jobs/269139303

The actual error is not directly visble in the Gitlab CI output, but
downloading the full build log shows this when building the kernel:

/tmp/cc2MGAgf.s: Assembler messages:
/tmp/cc2MGAgf.s:893: Error: .err encountered
scripts/Makefile.build:308: recipe for target 'sound/core/compress_offload.o' failed

This typically happens with old kernels, when building with gcc 8.x
(gcc 8.x is now our default gcc version).

Therefore, could you update the kernel version in this defconfig ?

While at it, could you add an entry in the DEVELOPERS file for this
defconfig ?

If you no longer have access to the board, or you're no longer
interested in maintaining this defconfig, please say so.

Thanks!

It still fails to build:

  https://gitlab.com/buildroot.org/buildroot/-/jobs/273673278

Will you have the chance to look into this? Otherwise we can simply
remove the defconfig.

Thanks,

[Buildroot] Buildroot ts7680_defconfig no longer builds

Hello Thomas,

Sorry for the late reply and thank you for pointing that out.

I was able to reproduce the issue with gcc 8.x and 9.x. With gcc 7.x
and Linux 3.14 the ts7680_defconfig is able to build.
Has anything changed regarding Buildroot toolchain handling since
previous release?

The ts7680 is not supported in upstream Linux, but Technologic Systems
recently added a 4.9 Linux repository [1] for their i.MX28 boards. I
am able to compile this kernel and generate a full system.

I will submit a patch to bump the kernel, but I no longer have access
to the board to test the build. I will CC people from Savoir-Faire
Linux who use this board so they can test and acknowledge the patch. I
would also ask if they can maintain the board in the future.

Regards,

Julien

We have switched to using gcc 8.x as the default compiler version,
hence the change.

OK.

Sure, I'll let you handle that with the SFL folks then.

Thanks for the feedback!
