Hi, I’m trying to create package for neovide: [GitHub - neovide/neovide: No Nonsense Neovim Client in Rust](https://github.com/Kethku/neovide)

`shell.nix`

```auto
let
  moz_overlay = import (
    builtins.fetchTarball
      "https://github.com/mozilla/nixpkgs-mozilla/archive/master.tar.gz"
  );
  nixpkgs = import <nixpkgs> { overlays = [moz_overlay]; };
  ruststable = (
    nixpkgs.latest.rustChannels.stable.rust.override {
      extensions = ["rust-src" "rust-analysis" "rustfmt-preview"];
    }
  );
in
  with nixpkgs;
  stdenv.mkDerivation {
    name = "rust-stable";
    buildInputs =
      [stdenv openssl pkgconfig cargo rustc rustup ruststable freetype];
  }

```

The error:  
`nix-shell -p --run 'RUST_BACKTRACE=full cargo build --release'`

```auto

```

Which is a bit odd because I can:

```auto
nix-shell -p --run 'curl https://libsdl.org/release/SDL2-2.0.10.tar.gz -o test.tar.gz' master
  % Total % Received % Xferd Average Speed Time Time Time Current

Perhaps you should try adding `SDL2` to your buildInputs, and removing the line in cargo.toml that forces SDL2 to be statically linked. That worked for me, and now I’m fighting with skia, as it’s non-trivial to package, and the crate assumes it can access the network while running build.rs.

Might be fair to request upstream changes to account for that.

True. I’d like to get my modified version building in nix before I submit any changes upstream.

Packaging skia and making it available to skia-rust is being a pain. In other news, neovide is very snappy on my machine, and I’m really enjoying the cursor wipe animation (when I tune down the time it spends in the animation), as it helps me keep track of the cursor more. This makes me wonder if it would be useful for a terminal, or if ncurses apps would make it noisy.

I have the same problem with skia-bings when packaging another rust app. Did you manage to resolve the problem?

Not really. I opened an issue, and a developer was able to help me get through some stuff (gn and ninja paths should be configurable on master), but I did not get much farther than that. I apparently don’t have the code anymore 😅 I don’t know how that happened.
