Hello guys! I’m trying to compile a rust-program with `cargo run` but I’m getting the follow error message:
```auto
(flakeshot:172220): GLib-GIO-ERROR **: 12:09:24.675: Settings schema 'org.gtk.gtk4.Settings.FileChooser' is not installed
Trace/breakpoint trap: oops, process 'cargo' core dumped
```
may I ask which package includes this `org.gtk.gtk4.Settings.FileChooser`?
[Here’s the devShell`](https://github.com/eneoli/flakeshot/blob/5473dbb08c9e8b766e83270f8f3379828f88ae2f/flake.nix#L79) I’m using.

I would think `gtk4`. Which you already have in the build inputs. So, hmmmm…

but `gtk4` is already included.

Yes, I see that now. What happens if you do something like `find /nix/store -name *FileChooser*`

looks like it’s in `gtk4`.

Yeah, hopefully someone more experienced than I will chime in, but my best guess is that you need to get the dev output somehow? [Nixpkgs 23.11 manual | Nix & NixOS](https://nixos.org/manual/nixpkgs/stable/#chap-multiple-output)

Also wondering if you need glib in your inputs, so it has access to gtk4?

I also added `glib` to `nativeBuildInputs`. Still getting the error.

Ok, I followed [this](https://discourse.nixos.org/t/gtk-file-dialog-causes-segfaults-glib-gio-error-settings-schema-org-gtk-settings-filechooser-does-not-contain-a-key-named-show-type-column/6853/2) post and executed
```auto
rm -rf ~/.local/share/glib-2.0/schemas
```
with
```auto
mkdir -p ~/.local/share/glib-2.0/schemas
cp -pi /nix/store/...-gtk+3-3./share/gsettings-schemas/gtk+3-3.*/glib-2.0/schemas/gschemas.compiled ~/.local/share/glib-2.0/schema/
```
as the next step but with `gtk4` instead of gtk+3.3.
Now I’m getting
```auto
(flakeshot:72854): GLib-GIO-ERROR **: 12:48:00.442: No GSettings schemas are installed on the system
```

You need to add [`wrapGAppsHook4`](https://nixos.org/manual/nixpkgs/stable/#ssec-gnome-hooks) to your `nativeBuildInputs`.

[Added](https://github.com/eneoli/flakeshot/blob/63ee749f529997b84cff68719034cacedd3476cb/flake.nix#L42) but I’m still getting

The [GNOME section of the Nixpkgs manual](https://nixos.org/manual/nixpkgs/stable/#sec-language-gnome) explains what you need, in this case it is adding appropriate paths to `XDG_DATA_DIRS` environment variable. `wrapGAppsHook4` does do this correctly but [only for built derivations](https://github.com/NixOS/nixpkgs/blob/65676856ac717c356f8ab7d5e055ec46d290a611/pkgs/build-support/setup-hooks/wrap-gapps-hook/wrap-gapps-hook.sh#L18), not `devShell`s, so it will not help you with `cargo run`.
There is no mechanism for shells at the moment, you will need to apply a hack like `shellHook` from [Python + Qt woes - #2 by jtojnar](https://discourse.nixos.org/t/python-qt-woes/11808/2) with `gappsWrapperArgs` instead of `qtWrapperArgs` if you want to make it work.

Do not do that, it will break GTK programs if the schema is ever updated.

damn… thank you for your answer!
