Describe the bug

Just try to run the hello world example and I get this error, by the way, I'm on linux.

How to reproduce

Trying to make the documentation hello world

Example code

    gi.NewButton(b).SetText("Hello World!")

Platform

Linux

I solved it by making a sudo ln -s /usr/share/fonts/TTF/ /usr/share/fonts/truetype

Either way, I think that's something that needs to be fixed.

Indeed, this should not happen. What distro of linux are you using? From some quick searching, it seems like most distros of linux store their fonts in /usr/share/fonts/truetype. Regardless, I will add support for finding fonts in /usr/share/fonts/TTF.

What distro of linux are you using?

I'm using Arch Linux

I implemented a fix for this in the commit above; can you remove your symlink, update to the latest version of Cogent Core (go get cogentcore.org/core@a33095d), and ensure that the error does not happen again?

The error no longer occurs, now it works correctly, thank you.
