Ok, so basically the window is not being created as there's no handle

Redhacker2•5/19/22, 10:44 PM

Try sdl

CCosmin Cretu Ok, so basically the window is not being created as there's no handle

Redhacker2•5/19/22, 10:45 PM

Just try to force SDL and see if you get a window. I know we don't want to support SDL long-term but just do it temporarily

Cosmin CretuOP•5/19/22, 10:48 PM

@redhacker2 I've just tried, with sdl it fails even earlier, at Window.Create

Redhacker2•5/19/22, 10:48 PM

Hmm odd

Lyris the Kitori•5/19/22, 10:49 PM

comment out your depth and stencil buffer settings, see if it still crashes

Cosmin CretuOP•5/19/22, 10:51 PM

Cosmin CretuOP•5/19/22, 10:52 PM

Still not working

Cosmin CretuOP•5/19/22, 10:52 PM

I thought for a second that is the nvidia driver, I've re-installed it but still nothing

Redhacker2•5/19/22, 10:52 PM

Idk

Lyris the Kitori•5/19/22, 10:53 PM

one sec lemme get my launch options which force software rendering

Cosmin CretuOP•5/19/22, 10:53 PM

It's really weird because it was working with the exact same way I was settings the window, then all the sudden it stopped

__GLX_VENDOR_LIBRARY_NAME=mesa LIBGL_ALWAYS_SOFTWARE=1 MESA_DEBUG=1

__GLX_VENDOR_LIBRARY_NAME=mesa LIBGL_ALWAYS_SOFTWARE=1 MESA_DEBUG=1

run your app through CLI with these environment variables set

Lyris the Kitori•5/19/22, 10:54 PM

er wait without 2 of those

Lyris the Kitori•5/19/22, 10:54 PM

those ones

Lyris the Kitori•5/19/22, 10:54 PM

should bypass nvidia

Cosmin CretuOP•5/19/22, 10:57 PM

no freaking way, just dotnet run works now

Cosmin CretuOP•5/19/22, 10:57 PM

I literally just tried it before I upgraded nvidia and didn't work

Cosmin CretuOP•5/19/22, 11:02 PM

For some reason it started working, I think it might've actually been nvidia drivers

Cosmin CretuOP•5/19/22, 11:02 PM

it's just that now I have a different problem with Skia, but that's a different story

Cosmin CretuOP•5/19/22, 11:03 PM

That or it just got scared when you said to try CLI with those options

Cosmin CretuOP•5/19/22, 11:03 PM

Thank you though!

I was having GlfwException with my project before, and it was fixed by changing my GPU from the integrated to dedicated one. Weird bug tbh

Cosmin CretuOP•5/20/22, 8:40 AM

Personally, I think this is an issue, games & other apps like chrome that use opengl, they work with or without the dedicated gpu

Kai•5/20/22, 8:42 AM

I don't have an integrated GPU to test, but I'd be rather confident this is a driver issue

Ҡєʀ๓aℓıѕ•5/20/22, 10:00 AM

I'm not sure if this is a relevant question (it's a GL question), but I'm getting a GL error in this project I'm working on:

Program undefined behavior warning: The current GL state uses a sampler (0) that has depth comparisons enabled, with a texture object (9) with a depth format, by a shader that samples it with a non-shadow sampler. This will result in undefined behavior

Program undefined behavior warning: The current GL state uses a sampler (0) that has depth comparisons enabled, with a texture object (9) with a depth format, by a shader that samples it with a non-shadow sampler. This will result in undefined behavior

The relevant file is here: https://github.com/Kermalis/HybridRenderingEngine-CS/blob/main/Assets/Shaders/PBRClusteredShader.frag.glsl

If I change to sampler2DShadow, then the error disappears, but shadows don't actually work. The resources I've seen don't use sampler2DShadow so I'm confused, since this error can be "ignored" and shadows render properly. I didn't make this engine originally so I would like to understand this
It's the only GL error remaining. The original creator didn't have GL debugging enabled so they never knew about it

That's a quite detailed question, I doubt anyone here will know this specific scenario. Try the graphics discord from the pins

Ҡєʀ๓aℓıѕ•5/20/22, 10:05 AM

I'll ask there in the morning, it's 6am for me and I need to be up at 12

Vazde•5/21/22, 6:51 AM

Question about the Vulkan APIs. Many of the capability queries are performed by first asking how many things there are, and then stackallocing a span, and asking for the things. Silk.NET is rather 1:1, but does there happen to be helpers for those cases? Or any other helpers like the Chains?

Supine•5/21/22, 8:25 AM

How normalized way (0 to 1) of angles are called?

Kai•5/21/22, 8:32 AM

For the queries there isn't right now, because there is no way to return stackalloced memory, and we don't want performance to suffer.
There are chain helpers though, they are behind

<RootStructure>. Chain

<RootStructure>. Chain

see https://github.com/dotnet/Silk.NET/tree/main/documentation%2Fstructure-chaining for details.

Vazde•5/21/22, 8:55 AM

Okay, thanks. I kinda remembered the same thing after asking. Of the chains I knew of, hence why I mentioned them. But does there happen to be any other helpers beside them? I don't have the need for them, but would be nice to be aware of what's available, while I'm learning about Vulkan in general.

Kai•5/21/22, 8:58 AM

I guess extensions are also neatly packaged into classes, other then that we don't have anything quite that high level.
Feel free to post ideas / problems / whatever here https://github.com/dotnet/Silk.NET/issues/887

Tracking Issue for Bindings Generation & Improvements · Issue #887 ...

TODO We truly invite everyone to send us reports of any place where our bindings are not ideal. This issue will serve as a list of things we should fix in 3.0.

Vazde•5/21/22, 9:04 AM

I'll try if I get any ideas :) I wasn't really expecting there to be anything too high-level, but the chains were a welcome surprise, so wanted to make sure I hadn't missed anything else.

Kai•5/21/22, 9:43 AM

The chains were an amazing contribution, I'm hoping to build more things like them into 3.0

Lyris the Kitori•5/22/22, 5:53 PM

not directly silk related, but how would i get a

DllImport

DllImport

asking for

d3d11.dll

d3d11.dll

to pick up a native linux library version? ive tried naming the file

libd3d11.dll.so

libd3d11.dll.so

d3d11.so

d3d11.so

libd3d11.so

libd3d11.so

d3d11.dll

d3d11.dll

and it always just says "failed to find native library 'd3d11.dll'

Lyris the Kitori•5/22/22, 5:53 PM

Perksey•5/22/22, 5:54 PM

just do

d3d11

d3d11

Perksey•5/22/22, 5:54 PM

as the import name

Lyris the Kitori•5/22/22, 5:54 PM

ill have to figure out how to compile vortice from source on linux then

Lyris the Kitori•5/22/22, 5:54 PM

hmm

Perksey•5/22/22, 5:55 PM

alternatively you can do a NativeLibraryNativeLibrary hook

Lyris the Kitori•5/22/22, 5:55 PM

how would i go about doing that?

Lyris the Kitori•5/22/22, 5:56 PM

NativeLibraryNativeLibrary doesnt seem to be a class anywhere, atleast rider isnt picking it up

Perksey•5/22/22, 5:56 PM

https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.nativelibrary

NativeLibrary Class (System.Runtime.InteropServices)

Provides APIs for managing native libraries.

Lyris the Kitori•5/22/22, 5:56 PM

ah its core only, so i need to put this code somewhere else

Perksey•5/22/22, 5:57 PM

yep

Perksey•5/22/22, 5:57 PM

though at this point i don't think there's any point targeting under 6 imho

Lyris the Kitori•5/22/22, 5:57 PM

we just do netstandard 2.1 just incase someone needs framework support

Perksey•5/22/22, 5:57 PM

lol
