I can do "dub add raylib-d" but i have no clue to program a simple moving circle.

Makes no sense. Can you post the dub.json?

I had Canvasity in dub.json , so i removed it.
My current dub.json is :

{
	"authors": [
		"x"
	],
	"copyright": "Copyright © 2024, x",
	"dependencies": {
		"raylib-d": "~>5.5.1"
	},
	"description": "A minimal D application.",
	"license": "proprietary",
	"name": "myprogram"
}

vscode no longer complains.

But "dub run" gives,

I see i don't have the raylib library installed. And there is none available on redcore-linux(a gentoo derivative).
Gone try debian now.

After installing raylib library on Debian ,
https://github.com/raysan5/raylib/releases

Running "dub run" i get now the error :

This is because you didn't have the library available.

I highly recommend using the raylib-d:install script as mentioned in the README

Not only does this copy the exactly correct library to your local directory, it also offers to update your dub.json to provide the appropriate linker directives for linking.

You are using an older version of gdc. I don't follow the gdc releases, but it's possible even the latest available doesn't support named parameters, as that is a recent addition.

In any case, I still recommend using the raylib-d:install script, and you can do this without having to install a library package from your OS.

dub run raylib-d:install

solved the problem. Thanks
