g-golf example error 'No applicable method for #<<generic> g-application-run'

[Mortimer Cladwell]

Hi,
I have installed g-golf with guix:
guix package -i guile-g-golf gtk guile-cairo

I try to run the hello-world example with the manifest.scm:

---manifest.scm--------------
(specifications->manifest
 '("guile"
   "guile-g-golf"
   "guile-cairo"
   "gtk"))
-------------------------------

mbc@ins3910:~/projects/g-golf/examples/gtk-4$ guix shell
guix shell: loading environment from
'/home/mbc/projects/g-golf/examples/gtk-4/manifest.scm'...
mbc@ins3910:~/projects/g-golf/examples/gtk-4 [env]$ ./hello-world.scm

Help!

Maybe a separate issue - I see at
https://www.gnu.org/software/g-golf/install.html:

"G-Golf actually requires a patched version of guile-cairo that contains
the following new interface (which is not in guile-cairo 1.11.2):
cairo-pointer->context."

Is there a solution for guix users?
Thanks
Mortimer

Hello,

I don't use guix and recommend that you ask for help in a guix ml or in
#guix, as this a guix problem, not a g-golf problem - all examples work
well upstream, in debian, and afaict, in freebsd.

Right - but guile-cairo is only required if you are using guile-cairo
in your g-golf code, wrt examples, only for the animated-paintable and
simple-paintable examples do required guile-cairo. The hello-world, as
well as all other examples, including the adw1-demo, do not require
guile-cairo.
