Hi Florian,

Thanks. You shouldn't have to do this 'on your own', if you submit a
reproducible minimal example that i can use, i'll track and fix
the bug ... If it is a distro problem, which is the situation you are
facing, you should talk to the distro (involved pkgs maintainers)
(additional tips below ...)
But i am curious, does make check pass in Guix?

I highly recommend you use Adwaita (and Gtk-4 when that applies), not
'just' Gtk-4.

Great - Proper GLib/GObject/GObject-Introspection libs is a
pre-requisite ofc, but Guix is known to wrongly set-up things: I think
Ricardo Wurmus <rekado@elephly.net> knows what to do, he did succeed,
once, to run the hello-world example in guix a few years ago, but i
didn't take note of what he did and can't find neither an email, nor in
the logs, how/what needs to be done - I think it has something to do
with grafts, iirc ... I hope he will shim-in to let you know ...

I am curious, can't you just run the make danse in guix?
./autogen.sh
./configure [--prefix=...] --with-guile-site
# before to run make, you need to uninstall
# g-golf (if it is installed ...)
make
Because i'd be interested to know the output of running make check,
in Guix that is ...
# it needs Gtk-3.0
make check

Never seen such a warning, I guess all other distro run the service by
default - i'll ask uptream, but maybe worth adding the service as a
g-golf 'start-up' requirement in Guix ...

in Guix that is ... no other distro reports nor even a single
warning/error ...

You should be able to solve this easily, or apply the suggested GTK_A11Y
env setting ...

From here, nothing will ever work - You and Guix guru, need to find out
why .. -the symptom is that in Guix, for some reason, you are trying to
import the Gtk(Gsk/Gdk) lib more then once, in the same memory session,
which won't work, as GObject is a dynamic typing system, all those
types are being defined at runtime, and none can be defined more then
once ...

... right, as i said, nothing will work - these segfaults because
guile/g-golf doesn't stop to (try to) run the app/example because of an
upstream lib (Critical)warning ... but in this situation, it is just
impossible to run any low level upstream lib function, such as creating
a drawing surface ...
when Guix can run make check, and the hello-world example, you 'll
likely be able to run any other example, if not, we'll dig on
appropriate time ...
David
ps: are you in #guix, #guile, if yes, what's your nick - ping me
there so we can chat - hopefully after Ricardo giives his advice to run
g-golf in guix ...
