Issues with the tutorial

[ryzendew]

so here https://docs.slint.dev/latest/docs/slint/tutorial/creating_the_tiles/

it asked you to do

fn main() {
    use slint::Model;

    let main_window = MainWindow::new().unwrap();

    // Fetch the tiles from the model
    let mut tiles: Vec<TileData> = main_window.get_memory_tiles().iter().collect();
    // Duplicate them to ensure that we have pairs
    tiles.extend(tiles.clone());

    // Randomly mix the tiles
    use rand::seq::SliceRandom;
    let mut rng = rand::thread_rng();
    tiles.shuffle(&mut rng);

    // Assign the shuffled Vec to the model property
    let tiles_model = std::rc::Rc::new(slint::VecModel::from(tiles));
    main_window.set_memory_tiles(tiles_model.clone().into());

    main_window.run().unwrap();
}

This leads to an Error

Some errors have detailed explanations: E0412, E0433.

error: could not compile `slint-rust-template` (bin "slint-rust-template") due to 2 previous errors

it also breaks things in app-window.slint

Wondering if i messed something up?

[ogoffart]

The struct TileData should be defined on the .slint file from previous steps.
Same for the Main window.

Do you still have the slint::include_modules!(); line to include the generated code?

[BPowell76]

I have issues with the Tutorial as well. My edition in Cargo.toml is 2024 and I have errors with slint::include_modules!();

I cannot get past the first page of the tutorial.

Below is the error message I get:

error: environment variable `SLINT_INCLUDE_GENERATED` not defined at compile time
 --> src/main.rs:1:1
  |
1 | slint::include_modules!();
  | ^^^^^^^^^^^^^^^^^^^^^^^^^
  |
  = help: use `std::env::var("SLINT_INCLUDE_GENERATED")` to read the variable at run time
  = note: this error originates in the macro `env` which comes from the expansion of the macro `slint::include_modules` (in Nightly builds, run with -Z macro-backtrace for more info)

error[E0433]: failed to resolve: use of undeclared type `MainWindow`
 --> src/main.rs:4:23

error: could not compile `slint-demo` (bin "slint-demo") due to 2 previous errors

My Cargo.toml:

[package]
name = "slint-demo"
version = "0.1.0"
edition = "2024"

[dependencies]
slint = "1.11.0"

[build-dependencies]
slint-build = "1.11.0"

[tronical]

That's odd. Do you have a file called build.rs?

[BPowell76]

@tronical No, I had started up a blank rust project in RustRover and then started writing the code from the tutorial. Let me see if that helps.

[BPowell76]

That fixed it. Thanks.

[iot-crazy]

Any progress on this please? I'm here almost a year after the original post, trying the template for rust and I get 63 errors immediately from just trying to build the template.

[ogoffart]

What error do you get?

[iot-crazy]

It was a lot of errors in atspi-common, the solution was to set a compatibility mode in the dependencies. But, this morning, even with several totally fresh projects, it worked every time and nothing has changed, so I have absolutely no idea what happened there.

[ogoffart]

I see, this was most likely caused by the release of the zbus_names 4.3.0 that broke atspi-common, but it got fixed by the release of zbus_names 4.3.1
