[SOLVED] linux-6.14.4-gentoo compile error

Message

Haven't had any kernel issues in a LONG time. Can't compile 6.14.4 from gentoo-sources and not sure where to look for the problem. Previous versions of 6.14 have compiled fine. My system just upgraded to gcc-15.1.0 as well so I'm not sure if that might be causing an issue.

If you need assistance, please follow the standard troubleshooting instructions. The information you showed indicates that a failure happened, but there is no error message, so we cannot help you using only what you showed so far. If you suspect gcc-15, you could try switching back to gcc-14. I recall seeing a LWN piece that there had been some problem in the latest release where gcc-15 became stricter with its warnings.

Looking like a gcc issue? I restarted the complie and it continued along further and stopped again, been repeating multiple times and slowly moving forward with the complie. It's treating warnings as errors and I finally was able to capture the issue.

This is where it ultimately stops not allowing me to continue further:

That looks like the issue I referenced. Use gcc-14, or disable this warning by pulling in Linus's commit 9d7a0577c9db35c4cc52db90bc415ea248446472 (sorry, no git.kernel.org link because that site now only serves a JavaScript based captcha instead of browseable content). This failure had been reported for 6.12 (not 6.14) as sys-kernel/gentoo-sources-6.12.4-r1 fails to make due to compilation warning using gcc15 and again as the (incorrectly titled) sys-kernel/gentoo-sources:2.12.25 failed compilation with sys-devel/gcc:15. For the latter, the poster meant 6.12.25, not 2.12.25. The issue is fixed in v6.15.

Thanks, I disabled CONFIG_WERROR and the compile was able to continue successfully.
