I didn't anticipate Our Paint gets this much attention but thanks for showing interest :D

I have a flake that manages to build (see below). When actually running, it expects the fonts to be in a particular location in the home folder, I haven't found a workaround for that yet. I'll open a PR once I can run it from this flake.

@ChengduLittleA Thanks for your work, I'm looking forward to playing around with this! The issue I run into is that Nix packages can't simply install fonts into the user directory. I want to patch in a different place to look for fonts, but I can't figure out what the best place for that would be. Any suggestions?

[ChengduLittleA]

Put the font folder directly adjacent to the executable should do the trick. There are 11 different relative/absolute paths that laGUI will search for its fonts. I will update the font configuration. In the source code... But I designed our paint to be portable so the font should come along with the software package (later I will include more custom font for icons). See my appimage for example

[fgaz]

I tried to package it in #209448. I don't know yet if it works because right now I'm on a computer with very low opengl version.

@ChengduLittleA could you add $PREFIX/share/fonts/lagui (or equivalent) to the font search path and have cmake install fonts there instead of in ~/.local? That would make this program easier to package. Alternatively, a cmake variable to set the location of existing fonts.

[jonascarpay]

Even if I put fonts in an expected location, I run into a segfault on startup. It might still be related to fonts (one fails to load for some reason), but either way there are more issues than just the font loading. Looking at the appimage script hasn't really helped me figure out what's up, so be warned I guess @fgaz

[ChengduLittleA]

@jonascarpay Any idea you could give me the stack trace on where it crashed? I think laGUI should not crash if there's at least one font that's loaded, so the crash might be other issue like graphics. (I later found out there's a typo in monospace font loader...)

@fgaz I updated CMake list to install fonts into a prefix if the variable is not manually set. Default is LAGUI_FONT_CUSTOM_PATH=$ENV{HOME}/.local/share/fonts/lagui . Go check out the latest code on my repo.

[fgaz]

It crashes for me too.

@fgaz could be a GL context init problem. You could delete the preference file, or try v0.1b again

Any progress here ?
