Hi, I'm packaging a piece of software which crashes when launching chromium embedded framework.
The error is Fontconfig error: Cannot load default config file: No such file: (null) I found a similar issue for Nix which suggests the error is caused by fontconfig not being installed globally and suggests a patch: https://github.com/NixOS/nixpkgs/issues/176081#issuecomment-1145903568 I tried creating a symlink at /etc/fonts/fonts.conf, but while I get further, it still crashes. sudo ln -s ~/.config/fontconfig/fonts.conf /etc/fonts/fonts.conf Fontconfig warning: no <cachedir> elements found. Check configuration. Fontconfig warning: adding <cachedir>/var/cache/fontconfig</cachedir> Fontconfig warning: adding <cachedir prefix="xdg">fontconfig</cachedir> Trace/breakpoint trap /var/cache/fontconfig is on a read-only filesystem, so I cannot experiment with adding it there. I tried adding all fonts and fontconfig to my system configuration, but this didn't generate /etc/fonts/fonts.conf nor /var/cache/fontconfig/*. Unfortunately, I haven't been able to test the Nix patch as my naive `-L ~/code/guix` fails to compile various modules. Any input before I spent a lot of time trying to get this Nix patch working?
