slint-demos recipe error with package.rust-version

Hello,

I'm unable to bitbake the slint-demos recipe due to this error:

Log data follows:

I'm not a Rust developer, so I don't know exactly what is going on. I can see this parameter is defined inside api/cpp/Cargo.toml with the workspace object:

rust-version.workspace = true

And here this is expecting a string. Can someone help me?

Thanks!

Proposal: Introduce yocto release branches for backwards compatibility

My propsal is to intruduce yocto release branches (e.g. krikstone, mickledore) for backwards compatibility. When someone is using kirkstone, there are no surprises when meta-slint upgrades to a new yocto version.

Yocto release names can be found here: https://wiki.yoctoproject.org/wiki/Releases

Add support for common distro features to select wayland/x11

The slint-cpp recipe should respect the distro features and select backend-winit-wayland/x11 respectively. Similarly, only if "OpenGL" is in distro features, we should enable OpenGL renderers. Same for Vulkan.

Add support for packaging slint-compiler with slint-cpp recipe

At the moment the slint-cpp recipe creates a library that only supports the dynamic C++ Slint interpreter API. Slint also supports compiling .slint files to .cpp files at compile time, which is more efficient and provides type-safety.

The cmake build by default produces a slint-compiler executable that's a host build, and the generated SlintConfig.cmake references that.

Unfortunately the current slint-cpp bit bake recipe does not handle this correctly. The produced binary should go into a native package (as opposed to target) and somehow the generated SlintConfig.cmake should be able to reference the slint-compiler binary from the host binary directory tree.

We need help to implement this properly using bit bake.

Update: This is work in progress.

The basic slint-cpp recipe now configures the Slint C++ compiler via a slint-cpp-native package and the slint class pulls that in and injects it into an application cmake build.
Document how to use this for real in apps
Add support for slint-compiler to SDK builds

Framebuffer Support

Does Slint Build support only Frambuffer ? X11 or Wayland are way too ressource hungry for a small system
