Version 5.0.0 crash on startup, GTK4 is missing?

[alexislefebvre]

I use Ubuntu 20.04.4.

I downloaded the 5.0.0 release but a dependency is missing:

cd /tmp/
curl --location https://github.com/qarmin/czkawka/releases/download/5.0.0/linux_czkawka_gui -o /tmp/linux_czkawka_gui
chmod +x ./linux_czkawka_gui
./linux_czkawka_gui
[…]
linux_czkawka_gui: error while loading shared libraries: libgtk-4.so.1: cannot open shared object file: No such file or directory

I tried to install the dependencies but it didn't work:

sudo apt install libgtk-4-dev ffmpeg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libgtk-4-dev

It looks like libgtk-4-dev only exists on Ubuntu 21.10+: https://packages.ubuntu.com/search?keywords=libgtk-4-dev

So people which use Ubuntu 21.10+ can use czkawka 5.0.0, the others have to use 4.1.0.

Yes, this is expected,
As workaround to use 5.0.0 version, flatpak build is required which allows to install app on older OS(not released yet)

Thanks for your answer, we should add a note about the versions here: https://github.com/qarmin/czkawka/blob/master/instructions/Installation.md#precompiled-binaries

Thanks for updating the README. Upgrade from Ubuntu LTS 20.04 to 22.04 will be proposed next week, when Ubuntu 22.04.1 will be released. So most users should be able to upgrade and get GTK4.
