[rust, curl, tls] neovide failed to run custom build command for `sdl2-sys v0.34.0`

Hi, I’m trying to create package for neovide: https://github.com/Kethku/neovide

shell.nix

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'

error: failed to run custom build command for `sdl2-sys v0.34.0`

Caused by:
  process didn't exit successfully: `/c/neovide/target/release/build/sdl2-sys-97227988e5290b8e/build-script-build` (exit code: 101)

Which is a bit odd because I can:

nix-shell -p  --run 'curl https://libsdl.org/release/SDL2-2.0.10.tar.gz -o test.tar.gz'                     master

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.
