On my x86_64-linux-gnu with a childhurd, util-linux fails to compile.

Some bits that seem relevant:

To be investigated ...

Yes, this is a “known problem”:

  https://issues.guix.gnu.org/43857

The problem is that the build environment on GNU/Hurd has yet to be
specified, which is what the patch above was partly trying to address
(though I think we could do better than spawn one firmlink translator
per store item…).

The “Isolated build environments” section of
<https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/>
discusses the broader issue.

If you’d like to get some Hurd hacking done, here’s a good opportunity.

I'll take a look.

Problem is, I was trying to create a VM with Hurd to my liking
with "guix system etcetera", to do some Hurd hacking.
(GNOME Boxes only accepts ISO's, no qcow2's)
But this command fails.  Both when cross-compiling (meson doesn't
support cross-builds yet), and when compiling ‘natively’ using
the childhurd --- apparently util-linux is in the dependency tree.

Maybe the tests should be disabled on the Hurd on now, in order
to be able to fix the underlying issues more easily?

Greetings,
Maxime.

What OS config did you try to cross-build?

It’s possible to cross-build minimal GNU/Hurd images, such as the one
used in the childhurd test in (gnu tests virtualization), or like the
gnu/system/examples/bare-hurd.tmpl example.

Cross-building GNU/Hurd images is probably the easiest way to get
started with GNU/Hurd hacking at this point.  I’m Cc’ing Janneke who has
more experience and maybe tips and tricks to share.  :-)

Yes, we could disable util-linux tests for i586-gnu with a FIXME
pointing to this discussion, to help further progress.  I’ll do that if
there are no objections.

Thanks,

The installer.

Yeah, that one probably has too much stuff; it has connman, which
probably pulls in GLib and all.

Done in 84feaca4888c9916e1a97bb81e5d157673488b70.

I’m closing this bug, with the understanding that we need a proper fix
for the underlying issue.
