bug#56223: h-client not running with a host distribution

Hi,

After having done a 'guix pull', I added h-client to a system image made
with guix system image, and when running that image I could launch
h-client with any of the following command lines:
$ h-client
$ sudo -E h-client

However with Parabola i686 (also after having done a 'guix pull',
h-client doesn't work anymore, and it gives the following error:

I vaguely remember that I could launch it on top of Parabola before, so
it seems to be related to recent updates to the h-client packages
(through before sending data didn't always work due to a bug in the
server that is now fixed).

PS: I've added Maxim in To as pers is the last person who worked on
    improving the h-client package, so maybe pers has more knowledge
    than me on that.

Denis.

Seems to me that gdk-pixbuf will need to be propagated, which will also
in turn propagate glib and set the search-path `GIO_EXTRA_MODULES` so
that GdkPixbuf can be found.

Best,

Hello,

This should be fixed in 8d810c209f18ffb635a1db2488a939543c6f060f.

It's odd, but the problem was caused by the lack of GI_TYPELIB_PATH.  I
wrapped that variable and also combined the phases from
glib-or-gtk-build-system and PATH (already wrapped scripts are skipped
instead of of composed) and now, the following works:

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix shell --pure h-client adwaita-icon-theme glib
--8<---------------cut here---------------end--------------->8---

glib is only added above to set XDG_DATA_DIRS and find the icons.

Thanks for the report!

Closing.
