Linux support: Docker, WINE, FNA

[westurner]

I'd like to run the Bricklayer server and client in free and open source Linux Docker containers:

• [ ] TST: WINE: server
• [ ] TST: WINE: client
• [ ] BLD: Docker container: server
• [ ] BLD: Docker container: client
• [ ] ENH,REF: Port to FNA
• [ ] BLD: Build for Linux (e.g. with dotnet-docker-samples/dotnetapp-dev/Dockerfile)

AFAIU, there are two ways to run a C# app with Linux:

• Run the .exe's with WINE
  • This should work today, but it'll require downloading all of WINE and isn't quite native.
• Build with .NET Core for Linux and find compatible alternatives for any other dependencies
  • XNA (Windows) -> FNA (Windows, Mac, Linux)

FNA

• Homepage: https://fna-xna.github.io/
• Src: https://github.com/FNA-XNA/FNA
• Docs: https://github.com/FNA-XNA/FNA/wiki
• Docs: http://pcgamingwiki.com/wiki/Engine:FNA
• Steam games
  • Enter the server URL and auth creds?

Dockerizing a .NET Core app:

  • https://github.com/dotnet/dotnet-docker-samples/tree/master/dotnetapp-selfcontained
    • Dockerfile: https://github.com/dotnet/dotnet-docker-samples/blob/master/dotnetapp-selfcontained/Dockerfile
  • https://github.com/dotnet/dotnet-docker-samples/blob/master/dotnetapp-dev/
    • Build, Unit Test, Publish
    • Dockerfile: https://github.com/dotnet/dotnet-docker-samples/blob/master/dotnetapp-dev/Dockerfile
  • https://github.com/dotnet/dotnet-docker-samples/blob/master/dotnetapp-prod/

GUI apps with Docker:

  • Share the X11 socket
  • VNC server

IDK much C# (though I did know C++ many years ago, and write mostly in Python now). Will these work with .NET Core on other platforms? I found FNA (links above) by searching for Microsoft.Xna.Framework linux

• "Lidgren built with mono fails on Linux" ... __CONSTRAINED__ https://github.com/lidgren/lidgren-network-gen3/issues/16
  • "Using Lidgren.Network with FNA" https://github.com/FNA-XNA/FNA/issues/83

First of all, you shouldn't really use .NET Core for Linux, as it requires itself to compile, so you have to download MS blobs. Please use Mono instead. (Wine is out of the question, really, and it uses Mono internally anyway.)

FNA is a drop-in replacement for XNA, so that should just work, except that assets have to be rebuilt. This shouldn't be a problem if you're trying to run the server.

About the Lidgren build: just define the __CONSTRAINED__ symbol as they say, and make sure Mono is up-to-date. Even Cyral himself commented in the first thread:

Compiling with CONSTRAINED fixes this error on mono for me.

The rest of the dependencies should work on any platform.

If you want to run it in docker, make sure it has the Mono runtime, then set up the environment as usual and run mono <binary.exe>. (Also, why would you want to run X11 stuff in a Docker container? If you want proper isolation for those, use eg. FireJail instead.)

---

FWIW, you might want to set these environment variables if things break:

FNA_KEYBOARD_USE_SCANCODES=1
FNA_OPENGL_DISABLE_LATESWAPTEAR=1
FNA_OPENGL_FORCE_CORE_PROFILE=1
FNA_GRAPHICS_FORCE_GLDEVICE=ModernGLDevice

Thanks!

Would a Makefile would be appropriate for a C# project? Or is there something more cross-platform?

To isolate the app dependencies from the host OS.

Thanks again!

This project is pretty much abandoned and if we ever continue with it we will most likely be using Typescript and WebGL to make it browser based. IIRC The server does work on Mono (although it has been years since I ran it) but the game would need to be ported to FNA or MonoGame. Neoforce controls is a beast and might not run on other platforms so easily since it does some stuff with 7zip to load the assets (Or maybe to export them, again its been a long time)

Got it.

React-VR looks pretty cool: https://facebook.github.io/react-vr/

AFAIU, only Chromium/Chrome have yet implemented WebUSB and WebBluetooth:

• Spec: https://wicg.github.io/webusb/

• https://caniuse.com/#feat=webusb

• Spec: https://webbluetoothcg.github.io/web-bluetooth/

• https://caniuse.com/#search=Bluetooth
