... I was at this very moment poised to ask about this very issue here, for, in
the case of a fresh guix 0.8.3 I was witnessing:
After `guix package --install emacs`, I find:
$ emacs
(process:3941): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
Gtk-Message: Failed to load module "canberra-gtk-module"
Gtk-Message: Failed to load module "pk-gtk-module"
The installed emacs v 24.5 does still start, and looks pretty snappy (despite,
alas, being build without svg support).
But, let me try and take your advice:
$ guix package -i libcanberra
$ export GTK_PATH=/gnu/store/*-libcanberra*/lib/gtk-3.0/modules
$ echo $GTK_PATH
/gnu/store/x06vfgf5fn09yr9crqlg22rwc301jnhp-libcanberra-0.30/lib/gtk-3.0/modules
$ ls $GTK_PATH
libcanberra-gtk3-module.la libcanberra-gtk3-module.so
libcanberra-gtk-module.so
But, upon starting emacs again, alas, I still get the same Gtk warnings and
messages.
Am I not following your advice, or otherwise mis-understanding it?
Thanks,
Malcolm
