Odd Shell Error After Successful Installation #935

Describe the bug

  • Distro: Gentoo (LLVM17)
  • Description:

I noticed that, after (re-)installing my kernel (6.8.9, which is also running at the time) that despite succeeding all the way to the end I got an "error 1" indicator in my shell for some reason. Confused, I checked the logs folder and the only thing I can imagine might have been the issue is a linker check in system-info.txt that failed for some reason due to a "permission denied" error.

Hello, please try again with latest linux-tkg commit to get the shell-output.log.txt file and attach it here.

It's failing at rebuilding the media-video/v4l2loopback module during emerge @module-rebuild, this is not a linux-tkg issue.

Thanks for clarifying; I don't recall it failing on my end (there was some at the end that wasn't appended to the log, for some reason, and I saw the usual install message) but I haven't seen anything else I could imagine it being :/

I could try running that part by hand when I have a moment later today/tonight to double check if it really fails though.

No, it does install; so that wouldn't make sense:

The install.sh simply calls emerge @module-rebuild, no extra magic. maybe you have a different kernel selected in equery kernel list

Just checked; no, I don't have a different one selected:

Available kernel symlink targets:
  [1]   linux-6.6.28-tkg-pds-gentoo-llvm-zen2
  [2]   linux-6.7.12-tkg-pds-gentoo-llvm-zen2
  [3]   linux-6.8.9-gentoo-dist
  [4]   linux-6.8.9-tkg-eevdf-gentoo-llvm-zen2 *

No idea then, you probably won't be able to reproduce this error next time you compile a kernel.

How is that the case when I reproduced it twice in a row so far? (Initially, then again to collect the log)
