I am developing an application that runs on Windows but not on Linux.
On Windows (MSYS2) pkg-config --modversion gtk+-3.0 returns 3.24.38.
On Linux pkg-config --modversion gtk+-3.0 returns 3.24.33.
I have tried sudo apt upgrade libgtk-3-dev but that does nothing so I am looking for a way to install version GTK 3.24.38 published here .
I have found build instructions elsewhere but is that my only option?
