I don't actually have time today to work on any side projects, but I thought I'd run through the basic setup steps for MonoGame aaaand
./bin/Debug/net6.0/MyGame
bash: ./bin/Debug/net6.0/MyGame: cannot execute: required file not found
... which required file ._. ???
I think this sort of thing means it tried to dynamically link something and failed. I run into this whenever I try to run loose builds of Linux games on #NixOS, but idk what to do about it.
@aeva It's amazing how bad the experience with runtime linker errors is on NixOS given that they happen with literally every prebuilt binary. In this case I would usually start by dropping myself into a basic dev shell: 'nix-shell -p stdenv'
@aeva 1. Was that wrong dotnet perhaps referring to an old ld.so that had been garbage collected? (and your executable invoking that as its interpreter akin to an incorrect shebang in say, a python file) 2. is the one that should be easy to figure out with ldd and LD_DEBUG=libs
ok new monogame-on-nixos mystery - I thought I got it working, but it turns out once a subclass of Microsoft.Xna.Framework.Game is constructed the process exits with no error printed to the console ._.
I'm still stumped on how to get #MonoGame working on #NixOS, but thankfully I have another computer with a real operating system on it, so please enjoy this overwrought Hello World I made using MonoGame tonight:
@Setzer22 it seemed fine with 10,000+ but I wanted the trails to not be too long. It's probably instancing quads under the hood, so, it should be pretty efficient.
I've made some progress on getting #MonoGame running on the hell distro! The surprise exit-without-error was a segfault (thanks strace!), which apparently was because #NixOS cleverly hid away udev, which is famously an optional component in all modern Linux distros. Now with that fixed, it simply cannot OpenGL:
"Unhandled exception. Microsoft.Xna.Framework.Graphics.NoSuitableGraphicsDeviceException: Failed to create graphics device!"
(fails somewhere in MonoGame.OpenGL.GL.LoadExtensions)
@jpab I can't imagine why lol. I might cave and use https://distrobox.it/ to run two distros at once, but the instructions want me to learn what a docker and a pod man are and I don't know if I'm ready to become that sort of person.
@thomastc@jpab it could be that distrobox is over selling how easy it is. I have no idea. They make it sound like I just need to setup that one thing, and then I can shell out to another distro that's nicely integrated with the host distro tho. It sounds too good to be true tbh.
@thomastc@aeva@jpab I've explored this topic pretty thoroughly and: If you want the game to use a GPU, no it's not simple and anything telling you otherwise is at best stretching the meaning of "easy"
@esther_alter@thomastc@aeva@jpab for another anecdote, I run games in containers all the time (with flatpak) - it worked out of the box, I never configured anything or followed a guide.
@ryanprior@esther_alter@thomastc@jpab I don't know flatpak - would I be able to set up a generic container for development this way, or would it still require me writing a Package instead of my game?
@aeva@esther_alter@thomastc@jpab flatpak does require packaging work on your (game developer's) part. It should be seamless for the gamer. If there's a guide to .NET packaging for flatpak that might put you on the right track.
@aeva nixos, It's Great For Development. I'm running it on my server but I can't imagine using it on a desktop, it's just so alien that I feel making software meant to be ran on other machines on NixOS is just asking for trouble
@duckonaut what I genuinely like about running NixOS is I can do things like decide to try KDE on a whim and then go "HOLY SMOKES THAT WAS A MISTAKE" and then just roll back to what I was doing before without toasting a bunch of random stuff glares at Debian
@duckonaut people told me I shouldn't use the package manager to install packages I'd use in userspace though, which makes no sense to me, but I don't mind having 100 shell.nix files everywhere.
@duckonaut so far running games seems to be a trial of error of downloading the linux version, then remembering that NixOS can't run Linux applications, and then downloading the windows version and running it in wine lol
@aeva@duckonaut You can safely ignore them and yeet everything into environment.systemPackages. I've been doing that for years and the high court of NixOS hasn't been able to punish me yet.
@aeva@anselmschueler@duckonaut It may seem so but that is really not the case. You see a way to install packages is just a morphism from packages to system configurations of of which there is in fact an uncountable number!
@aeva this remind me the time I installed an openbsd machine, installed openarena, made a second user, started openarena and boom, crappy fps. Turns out, hardware acceleration require to be in the video or staff group.
I've noticed this thread showing up in search engines while trying to research the problem, so for the benefit of any poor souls who might be out there trying to figure this out present or future: I gave up.
oh good, [wayland or gnome or whatever I don't care anymore] is forcing DPI scaling on the MonoGame window, and there's probably no way to prevent this because forcing it to use wayland instead of x11 just breaks it.
@aeva As a gnome user I very much regret to inform you that this is a Wayland problem but it's a Wayland problem exclusive to the Gnome Wayland server, the KDE Wayland server does not have this limitation.
@mcc@aeva that's because every distribution of Wayland has a different set of extensions built in, providing subtly (or sometimes radically) different functionality! Isn't Wayland great?
perhaps by the time everything has been forcibly rewritten to target wayland instead of x11, they'll decide that wayland just isn't hot and exciting anymore and we'll all just have to go convert everything all over again to use gofuckyourselfland instead
@tess@aeva I mean, you can probably make it still work comparing gcc to GNOME's Wayland compositor (Mutter?), and Wayland to some imaginary language designed to replace the entire C99 standard with … an efficient printf ABI or something like that.
@aeva look don't worry about it, the third committee meeting about wayland high dpi scaling is well into its 6th year, and all portents agree that a swift resolution is in sight.
ok this may seem backwards given the video I posted last night of the psychedelic spirograph thing I made, but you'll just have to take my word for it that I'm now branching out to doing more complex things with MonoGame.
@aud What I've come to appreciate over the years is that there's no unified entity called Microsoft. There's lots of things called Microsoft that are working cross purposes to one another, and some of these Microsofts are doing positive things and some of them very much are not. Same as anything else. The people who think otherwise (good or evil) are nursing a fantasy that anyone with any power has any plan at all.
@aeva Yeah, it's why I like to point out that while I dislike Microsoft as a business (and am personally still very angry at them), there are a lot of people I've met that are doing good work there.
Of course, if the eye of the C suite hits that area of the company, things can go poorly rather fast. And it's a fool that trusts a company beyond what a contract will stipulate, because there are so many shifting entities behind the enforcement (or lack thereof) of the contract that, well, what is there to trust? Who are you dealing with when it comes to brass tacks? etc etc etc.
@aeva Don't worry - the way gnome has been approaching standards lately, you'd probably be looking at a gnome specific wayland-less stack at that point - with arbitrary behaviour based on "that's what looked more neat & took up less bullet points on my slide deck" ;)
@aeva I’m sorry this has been so painful :( My experience with nix has been similarly frustrating at times. The declarative nature has paid off dividends to me but game dev may be different.
@eljojo I'll find a way though eventually. It might be "do the development in a vm and let someone else worry about packaging it", but eh.
This particular adventure aside, I do really like NixOS as a operating system for most things. There's a lot to like about it, but in this particular case I just want to work on my game today and nix just really really wants me to not be doing that :/
