Hi,

When building ffmpeg-4.2.2 (current master, 8d1b22b27fba3d1e4310f02a5897d231b42ca117)
natively on 32bit hardware, the build fails because of two failing tests
(full log attached)

How to attempt fixing this?

Building it on 64 bit hardware (much faster!) works for me, i.e. this

    guix build --system=i686-linux ffmpeg

works for me and can be used as a substitute...

Together with qemu-minimal-2.10 depending on ffmpeg
(https://bugs.gnu.org/39737) and no available substitutes this made for
a pretty rough "guix system reconfigure"-experience today.

I worked around this by adding a ffmpeg package that ignored the check
phase (#:tests? #f); I am wondering if we could we enable (something
like) that from the command line?  WDYT?

Apart from this hiccup I had a smooth upgrade from guix 0.14,
impressive!

Greetings,
janneke

I'm also hitting this bug, though the failing tests are
different. Here, audiodsp fails. Current commit is

Bah, it’s an all-too-common kind of failure.  :-/

We could add a package transformation option that adds #:tests? #f.
WDYT?

Though it’d be nice to not have test failures in the first place.  :-)

From 0.14, woow.

I don't have real 32 bits hardware to test on, but could you please test
ffmpeg 4.4 on such hardware if you have a chance and see if the issues
still exist?

Friendly ping. :-)

Is ffmpeg still an issue an real 32 bits hardware?

I do not have real 32 bits hardware to test on, but

    guix build --system=i686-linux ffmpeg

works for me with Guix 6113e05.  It outputs:

/gnu/store/wprpm76xy3b0312579dgv0akzy6k9llh-ffmpeg-6.0-debug
/gnu/store/y2mvpk6bna381ldskfmh6rzy1j34xnms-ffmpeg-6.0

Moreover, CI reports the failures for:

  v3.4.11 https://ci.guix.gnu.org/build/1836841/details

and passes for:

  v2.1.3 https://ci.guix.gnu.org/build/2041193/details
  v2.8.20 https://ci.guix.gnu.org/build/1836825/details
  v4.4.2 https://ci.guix.gnu.org/build/1836824/details
  v5.1.3 https://ci.guix.gnu.org/build/1836833/details
  v6.0   https://ci.guix.gnu.org/build/1836842/details

Therefore, I am in favor to close it.

WDYT?

simon
