Sounds good @AlixANNERAUD?

Yeah that seems a good start.

Hi @AlixANNERAUD for the lvgl-sys move, should we discuss it in the other issue or here is ok?

In the opened issue, I think. I already left comments.

I've added an item about cross-compilation, from the previous issues and PR's I think it stopped working somewhere. Have you tried to compile for embedded targets @AlixANNERAUD ?

@elrafoon I saw you are interested in LVGLv9 support, maybe you're interested in this

Yes, I’ve also tried (and succeeded) in the past on ESP32 family. Libraries with C-to-Rust bindings are notoriously tricky to build, mainly due to linker and libclang path configurations in the build script when using clang and bindgen. Additionally, the build script for lv_binding_rust—particularly lvgl_sys—is quite complex, which further complicates matters.
