Update: on like the 4th rebuild of the same .drv this succeeded, I guess it's intermittent?

Atemu commented 1 year ago

@JJJollyjim which filesystem is your build dir in?

JJJollyjim commented 1 year ago

btrfs

Atemu commented 1 year ago

I can't debug µArch differences like this and I'm not willing to spend significant time on supporting a dead platform.

I'll unsubscribe from here, ping me if I can help with something specific.

jleightcap commented 1 year ago

Reproduced with github:nixos/nixpkgs/master#pkgsi686Linux.ffmpeg_5.

The test log shows the issue being with time being impure:

--- ./tests/ref/vsynth/vsynth2-rv10     1970-01-01 00:00:01.000000000 +0000
+++ tests/data/fate/vsynth2-rv10        2023-05-10 06:38:15.750381772 +0000

If you just want steam to work, disabling this test (or just the whole checkPhase) may be the path of least resistance.

A proper fix would be to root cause why i686 fails this test while x64 (presumably) does not.

jleightcap commented 1 year ago

For root causing, work backwards from around http://git.ffmpeg.org/gitweb/ffmpeg.git/blob/963937e408fc68b5925f938a253cfff1d506f784:/tests/ref/vsynth/vsynth2-rv10.

Closing as we droped ffmpeg_5 support in #326618
