Description Mathieu Dubois-Briand 2025-10-13 11:49:37 UTC 
Happened twice, at one week interval.

2025-10-02 13:53:22,760 - oe-selftest - INFO -       ERROR: ffmpeg-8.0-r0 do_compile: Execution of '/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/work/x86-64-v3-poky-linux/ffmpeg/8.0/temp/run.do_compile.2432237' failed with exit code 1
...
ERROR: oe_runmake failed

I grabbed the log of today build, and in there we have:
/bin/sh: fftools/resources/graph.html.gz: No such file or directory

So, maybe a dependency issue?

Comment 4 Randy MacLeod 2025-10-16 14:41:37 UTC 
Sounds like a race or a floating dependency in the Makefile.
Comment 6 Simone Weiß 2025-11-26 21:42:33 UTC 
This should be the same issue as observed in by gentoo fols here: https://bugs.gentoo.org/965687
Comment 8 Alexander Kanavin 2025-12-04 12:18:41 UTC

Comment 13 Alexander Kanavin 2026-01-06 11:13:24 UTC 
For whinlatter these two should be cherry-picked:

9dbd2141b5 ffmpeg: add a (possible) build race fix
86396b85b4 ffmpeg: fix a build race, hopefully for real this time

@Yoann this has been fixed in master a while ago, cherry pick the patches from comment 13, and whinlatter will be fixed too.

@Alex (Sorry I did not reply earlier)
I saw your comment #13 and noted to backport these.
I will do it for the next whinlatter patch review/merge series (sometime in the next 2 weeks)

I only commented my failed build to be sure to have every AB-INT failed build triaged but, in this case, the solution is known.

Thanks!
