One way to reproduce it is:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build -e '((@ (gnu system image) system-image) (@ (gnu system images hurd) hurd-barebones-qcow2-image))' -n --no-grafts
guix build: error: gnu/packages/glib.scm:181:2: [email-masked]: build system `meson' does not support cross builds
--8<---------------cut here---------------end--------------->8---

or:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(gnu system images hurd)
scheme@(guile-user)> ,use(gnu image)
scheme@(guile-user)> ,use(guix)
scheme@(guile-user)> ,use(guix grafts)

The problem here is that, when populating in ‘packages->manifest’,
called from ‘packages->profile-entry’ in (gnu services),
(%current-target-system) is #false.

This is fixed by commit 07a33b1d21e240781072352f93206cfdc765f907.

Sorry that this spoiled the pleasure of merging service discovery
support!

Thanks,
Ludo’.

Hello,

When I pushed this patchset[1], I didn't anticipate that Avahi depends
on glib which doesn't cross-compile. To fix the situation, I pushed
d9f05c70a6af1087de1717ff20036efa1afef5fb and
35a32fefb4695442265809805145b7a262ae4988.

While, it now allows to build and cross-build Guix, there's still an
issue when evaluating the "guix-master" specification with the CI.
It looks like "%current-target-system" doesn't have the expected value
in the propagated-inputs.

There's a backtrace of the situation as attachment. I'd like to find a
quick fix instead of reverting everything. Maybe removing "guile-avahi"
from the propagated-inputs of Guix could work. I'm not sure why it's
needed anyway because this library is already added to the wrapped guix
binary.

Thanks,

Mathieu
