Gtk warnings on launch in Ubuntu 16.04 #48

Closed poretsky closed 1 year ago

poretsky commented 1 year ago

There is a lot of gtk warnings in Ubuntu 16.04 in addition to the fontconfig one mentioned in #10.

The first one is a complaint about locale support:

(process:17738): Gtk-WARNING **: 09:34:08.058: Locale not supported by C library. Using the fallback 'C' locale.

And then a bunch of theme parsing errors as follows:

I've squeezed out the most of repetitions. There were several hundreds warnings in total.

Unfortunately this sort of thing is inevitable when trying to run something like the emacs snap which is a single build of an application with all its dependencies bundled together. As it uses a much newer GTK versions etc than what was present on Ubuntu 16.04, when trying to read the users/systems Gtk configuration settings it will then complain about deprecations etc. As such it is not really possible to fix this, other than using a much older version of GTK for the snap, but then that would look out of place on newer distros. Since Ubuntu 16.04 currently only makes up about 0.7% of the users of the emacs snap this will not be changing unfortunately. I suggest you may just have to live with seeing these errors, or you could write a small wrapper script to filter them out, or upgrade to a newer Ubuntu release.

And wouldn't help somehow making a snap without gtk dependency like emacs-lucid packages in Ubuntu?
