It turns out that [jmb's comment](https://software.codidact.com/comments/thread/11033#comment-27410) was correct; my version of `gio` was too old. After being led by Virgil through the nine circles of dependency hell, I eventually just upgraded to Ubuntu 25. Unfortunately I don't remember whether I then had to manually install the newer version of `gio` or not, since there were lots of things I had to fix to get the new Ubuntu version working, and even then the upgrade is still a tiny bit broken in places. The latest versions of the `gtk4` Rust library require a `gio` version of 2.82 or newer, so you can use this command (as suggested in [jmb's comment](https://software.codidact.com/comments/thread/11033#comment-27410)) to check whether you have the correct version: ```bash pkg-config --libs --cflags gio-2.0 'gio-2.0 >= 2.82' ``` If you don't have the right version, you'll get a message something like this: ```text Package dependency requirement 'gio-2.0 >= 2.82' could not be satisfied. Package 'gio-2.0' has version '2.53.1', required version is '>= 2.82' ```
