Maybe I'm missing something somewhere...

Reproducible: Always

Same goes with other external module, e.g. net-misc/r8168.

Sorry, the above reference link content is faulty.

Here's a valid snippet instead:

make -C /usr/src/linux M=/var/tmp/portage/net-misc/r8168-8.051.02/work/r8168-8.051.02/src modules

How are you building your kernel? If doing it manually, it probably calls gcc via 'gcc' and not the full tuple name, while ebuilds prefer it in full as behaviour can vary.

CONFIG_CC_VERSION_TEXT in e.g. /proc/config.gz should tell you. In any case, it's not a problem, just noisy.

Same here. I'm building kernel manually (make install).
Which command to use to get the same compiler names?

Comment 5 CaptainBlood 2023-10-01 14:30:09 UTC

Seems fixed as it doesn't occur any longer in sys-fs/vhba-20211218-r2.
