- Compile SDL2:
$ embuilder.py build sdl2
Compiling
Compile the Web version:
make web
Compile the native version:
make native
Running
To access the web version you need to serve the static files as web pages locally. We use python3 for that. If you
have Python 3 installed, you can run:
make serve
Now you can access locally the project running at http://localhost:8000/lvgl_example.html .
For running natively, you can do:
cargo +nightly run --release
