I'm on NixOS + Wayland (hyprland).
\nHow to configure the backend? (tried SLINT_BACKEND=winit but same result)
Slint will dynamically open the wayland libraries, it will try to open libwayland-client.so.0 or libwayland-client.so. Are those accessible in your Nix environment?
How do I configure the backend? Error initializing winit event loop

Are there any plans for these to be bundles with rust builds, similar to how you can have self-contained apps in.Net? |

@WhiteBlackGoose , what else would be needed here in order to run the slint examples using opengl? I can't seem to get the example window to display on wayland using plasma 6 regardless of slint backend: ruffsl@nixos ~/g/s/s/e/opengl_texture (master) [SIGINT]> RUST_BACKTRACE=1 SLINT_NO_QT=1 SLINT_BACKEND=winit-femtovg cargo run
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.59s
Running `/home/ruffsl/git/slint-ui/slint/target/debug/opengl_texture`
^C⏎For references, here is the { pkgs ? import <nixpkgs> { } }:
let
libPath = with pkgs; lib.makeLibraryPath [
fontconfig
libxkbcommon
wayland
];
in
pkgs.mkShell {
packages = with pkgs; [
openssl
pkg-config
];
LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${libPath}";

Nevermind. The solution was as simple as adding libPath = with pkgs; lib.makeLibraryPath [
fontconfig
libxkbcommon
+ libGL
wayland
]; |

For fellow nix newbies like me, this is where it goes in my devShells.default = mkShell {
buildInputs = [
openssl
pkg-config
rust-bin.beta.latest.default
];
packages = [ pkgs.bashInteractive ];
# TODO: Read on shellHooks
shellHook = ''
# alias ls=eza
# alias find=fd
'';
LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${ with pkgs; lib.makeLibraryPath [
wayland
libxkbcommon
fontconfig
] }";
}; |

If someone wants to use it with oxalica/rust-overlay # flake.nix
{
description = "rust devshell for linpull";

nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
rust-overlay.url = "github:oxalica/rust-overlay";
flake-utils.url = "github:numtide/flake-utils";
};
outputs = { self, nixpkgs, rust-overlay, flake-utils, ... }:
flake-utils.lib.eachDefaultSystem (system:
let
overlays = [ (import rust-overlay) ];
pkgs = import nixpkgs {
inherit system overlays;
};
in
{
devShells.default = with pkgs; mkShell {
buildInputs = [
openssl
pkg-config
eza
fd
rust-bin.beta.latest.default

LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${ with pkgs; lib.makeLibraryPath [
wayland

fontconfig
] }";
shellHook = ''
alias ls=eza
alias find=fd
'';
};
}
);
}Run |

A note for xorg/x11, at the least you'll need a few more libraries based off of stracing startup. Of which maybe we could get the libraries searched for in the backtrace? |

a recent update: I require # build

;also, to any passerby who will hear it: LD_LIBRARY_PATH is a really bad solution in nix, generally considered an antipattern, and unnecessarily verbose to boot.. just putting this stuff into |
