error: could not compile `gpui-shell` (lib) due to 7 previous errors

Windows 11
gpui kit 0.6.6
Rust 1.98.1

[huacnlee]

Thanks for the report. These errors don't come from Windows or the toolchain. They come from how the new workspace is set up.

Why it fails

The example depends on gpui-component-story, and the story pulls in gpui-shell (QuickJS + LLRT). gpui-kit's root Cargo.toml has this:

[patch.crates-io]
rquickjs = { path = "crates/shell/rquickjs-compat" }

Cargo only applies [patch] from the workspace you are building. In your own workspace the patch is missing, so the LLRT crates resolve rquickjs from crates.io while gpui-shell uses quickjs-jit. You end up with two rquickjs_core crates, and that is exactly what the multiple different versions of crate rquickjs_core notes say.

Fix (recommended): depend on gpui-kit only

A standalone app doesn't need the story crate. gpui-kit re-exports GPUI, so you don't need to list gpui, gpui_platform and the other GPUI crates either:

[package]
name = "example-stream-markdown3"
version = "0.1.0"
edition = "2024"

[dependencies]
gpui-kit = { path = "E:/Rust/gpui-kit/crates/kit" }
rand = "0.8"
smol = "2"

Then replace the two story helpers in main:

fn main() {
    gpui_kit::application().with_assets(Assets).run(|cx| {
        gpui_kit::init(cx);
        cx.activate(true);

        let bounds = Bounds::centered(None, size(px(600.), px(800.)), cx);
        gpui_kit::open_window(
            WindowOptions {
                window_bounds: Some(WindowBounds::Windowed(bounds)),
                ..Default::default()
            },
            cx,
            Example::view,
        )
        .expect("failed to open window");
    });
}

Also copy fixtures/test.md next to the project and fix the include_str! path. I checked this setup in a separate workspace: it builds, and QuickJS is no longer in the dependency graph.

If you really want to keep gpui-component-story, add the same patch to your workspace root, delete Cargo.lock, and build again:

[patch.crates-io]
rquickjs = { path = "E:/Rust/gpui-kit/crates/shell/rquickjs-compat" }

Checking the system installation

If the build still fails after this, compare your machine with our Windows CI (.github/workflows/ci.yml, windows-latest, target x86_64-pc-windows-msvc):

• Rust: stable, installed with rustup. rustup show must report an x86_64-pc-windows-msvc host, not -gnu.
• MSVC: Visual Studio 2022 (or the Build Tools) with the Desktop development with C++ workload, which provides the MSVC linker and the Windows SDK.
• CMake: on PATH.

script/install-window.ps1 in the repo installs the last two. To check the environment itself, run CI's command from the gpui-kit checkout:

cargo test --workspace --exclude gpui-shell --features gpui-component-story/test-support --locked

If that passes, the toolchain is fine, and any remaining failure is in the new project's manifest.
