I would like to know if and how GTK 3.24 can be currently supported with Snap.
I already wrote about this topic in a previous thread about GWE, but I decided to create this specific thread to better track the issue.
I already tried to use gnome-3.30-1804 but, while I’m writing, is not working at all.
Does anyone know if a Snap app already managed to achieve this? Is it even achievable at the moment?
We have quite a few GNOME 3.30 snaps already, being built with the gnome-3-28-1804 platform snap. I suspect what you are really looking for is GTK 3.24, rather than GNOME 3.30. Is there anything else that you need a newer version that what’s provided in 18.04? Maybe dazzle, but that’s pretty trivial to build into your snap.
Actually I’m not sure if what is needed is GTK or Gnome, what I know is that libdazzle shipped with Ubuntu 18.04 is not providing the needed method to add values to the model using Python introspection.
Maybe you are right and I just have to build libdazzle form the sources to get the version shipped with Gnome 3.30, but I have no idea how to do it with Snap.
If you have some time could you please give me some hints on what should I change in the snapcraft.yaml to achieve that?
EDIT
This how the flatpak’s libdazzle module of GWE looks: https://github.com/flathub/com.leinardi.gwe/blob/master/libdazzle.json
So I’m trying with this:
libdazzle:

meson-parameters:
- --prefix=/snap/gwe/current/usr
organize:
snap/gwe/current/usr: usr
build-packages:
- build-essential
- libgtk-3-dev
But looks like dazzle want GTK 3.24:
Dependency gtk+-3.0 found: NO found '3.22.30' but need: '>=3.24.0'
Found CMake: /usr/bin/cmake (3.10.2)
Dependency gtk+-3.0 found: NO (tried cmake)
src/meson.build:86:0: ERROR: Invalid version of dependency, need 'gtk+-3.0' ['>=3.24.0'] found '3.22.30'.Ok, I’m trying to build the entire damn GTK 3.24 but, after building all the dependencies, it fails on building gtk:

@kenvandine any suggestion?
Let me work on it a bit more tomorrow. I had built gtk into your snap last week but I was having issues with two versions of GTK in the snap (one built from source and one from the bionic package).
bump 
We have made some good progress. We’ve gotten gtk master to build in the gnome-3-28-1804-sdk build snap. This logic could be used in your snap, or perhaps we could get your snap building with the build-snap rather than build-packages. We’re actively working on finishing off the build-snap and I’ll keep you posted. If we don’t get anything soon, I’ll send you a patch which builds gtk as a part in your snap.
