Hi,
I’m a beginner and am using builder and glade.
On my Ubuntu (20.04) I am unable to install GTK4 for some reason, so I settled for using GTK3.
However, when I use Builder it uses GTK4 and it uses it successfully, obviously the application has its own binaries for it. I’m using the new project template for gtk, but when I try to change dependency(‘gtk4’) in the meson.build to dependency(‘gtk3’) it says gtk3 is not found, despite it being installed. Why is this?
Also, when I look at the -window.ui file in the UI designer it gives the following warning: The following required catalogues are unavailable: gtk. What is going on here?
I am a bit confused about how and where builder gets its gtk libraries .
