Haxe + OpenFl Could not initialize SDL: No available video device.

desttinghim commented 6 years ago

Issue description

I am trying to do some basic development work with Haxe and OpenFl. I can get OpenFl projects and samples to compile, but I can't get them to run. I get this error:

Could not initialize SDL: No available video device.
Could not create SDL window: No available video device.
Could not create SDL renderer: Invalid window.

I asked about this on the OpenFl forums. I found I didn't quite have all the libraries installed, so I installed them. The libraries in question are libX11, libXext, libXinerama, libXi and libxrandr. Installing these libraries did not seem to help.

I then asked on the #nixos irc channel and was guided to set LD_DEBUG=libs in the environment. This was the output.

Looking at the printout, it looks like ld is unable to find the libraries I had installed, and it looked in the wrong places. I am not sure how to coerce ld into looking for the libraries in the correct locations.

Steps to reproduce

nix-env -iA nixos.haxe
haxelib install openfl
haxelib run openfl setup
haxelib run openfl create HelloTriangle
haxelib run openfl test linux

This works for me with default.nix below:

{ pkgs ? import <nixpkgs> {} }:
with pkgs;
stdenv.mkDerivation {
  name = "haxeapp";

  # export paths to be able to run tests
  LD_LIBRARY_PATH = with xorg; "${libX11}/lib:${libXext}/lib:${libXinerama}/lib:${libXi}/lib:${libXrandr}/lib:${libglvnd}/lib";

  buildInputs = [ stdenv pkgconfig libglvnd ] ++
    (with xorg; [ libX11 libXext libXinerama libXi libXrandr ]);
}

As an option you can simply run nix-shell to test it:

$ nix-shell
$ haxelib run openfl test linux

Of course, you should use wrapProgram for executables to create final nix derivations (packages).
