Deno: Doesn't build in NixOS 20.03

[Xe]

I'm trying to play with deno but the binary doesn't work on NixOS:

$ ./deno
Failed to execute process './deno'. Reason:
The file './deno' does not exist or could not be executed.

LDD reports this:

$ ldd ./deno

And additionally when I try to build deno from source I get this rust error:

$ cargo build --release
error: failed to run custom build command for `rusty_v8 v0.4.2`

Caused by:

I'm not entirely sure what could be failing here, but whatever it is it's making this not work for me. I'm using NixOS 20.03:

$ cat /etc/os-release
NAME=NixOS
ID=nixos
VERSION="20.03.1822.5adf2a6c116 (Markhor)"

Do you have any ideas as to why this is failing?

[SyrupThinker]

You need to change the dynamic linker in the prebuilt binary.
For the build you need to have the following dependencies available:

rustChannels.stable.rust
python2

Additionally here is the current packaging effort.

[SyrupThinker]

The following is my derivation for the prebuilt binary

{ autoPatchelfHook, fetchurl, stdenv, unzip }:

stdenv.mkDerivation rec {
  name = "deno-bin-${version}";
  version = "1.0.0";

  src = fetchurl {
    url = "https://github.com/denoland/deno/releases/download/v${version}/deno-x86_64-unknown-linux-gnu.zip";
    sha256 = "0aknxy9z5cvw091yaw5yf2zynwzxs39ax3jkqdg10xw344jsyn31";
  };

  nativeBuildInputs = [
    autoPatchelfHook
    unzip
  ];

  unpackPhase = ''
    unzip $src
  '';

  installPhase = ''
    install -m755 -D deno $out/bin/deno
  '';

  meta = with stdenv.lib; {
    homepage = https://deno.land;
    description = "A secure runtime for JavaScript and TypeScript";
    platforms = platforms.linux;
  };
}

@Xe as @SyrupThinker has said already you needed to use the patchELF tool link

When you've got a binary that looks like the right architecture according to file's output & all the libs are linked according to ldd's output, this is usually the last step to making the binary work :slightly_smiling_face:

Are you happy to close this issue or is there anything else we can help you with?
