Also I would like to note that upstream here is extremely careless about their code change consequences, and dont perform any kind of QA of their code at all. But, despite that, I would still like to keep this package as upstream as possible to welcome new features as they pop in.

So, If this package does not build anymore, please, let me know! Thank you!

Yeah I have no idea about the iGPU, its obviously missing something. Maybe its a MESA/RADV issue. But the 4090 with open-nvidia drivers works.

@theriddick: :) also https://aur.archlinux.org/packages/raytracinginvulkan-git?O=20#comment-911371

I'll push a commit soon. It's basically the same test PKGBUILD plus an additional launcher script to avoid the cd command.

I have the same issue "cannot find a device" with an NVidia GeForce 730. Not sure what I'm doing wrong, and the wiki doesn't help... I don't have the power to investigate further, but at the very least the package builds.

Not sure what to do about the other issues you have, maybe they should be upstreamed.

And finally, if you have suggestions/patches let me know.

@a821 No I didn't go into the folder and run it like that. And I just did then and well, it works! LMAO oops.

So I guess you just gotta figure out why your iGPU isn't liking RT.

I should test this on my AMD 9950X3D iGPU which I have hooked up. Not sure if it handles RT really. (NOPE, spat out FATAL: failed to enumerate (ERROR_SURFACE_LOST_KHR))

I do notice the app doesn't adjust the resolution with scaling set. I have %150 scaling and its setting a resolution %50 higher then specified.

yes, probably some setting or env var is missing on my setup, but vulkaninfo output looks OK to me and I don't have time to debug ATM here.

Just a little thing before I deep dive into the issue: in your previous comment you ran /opt/raytracinginvulkan/bin/RayTracer, but did you try to run it like the pinned comment? (cd /opt/raytracinginvulkan/bin ; ./RayTracer ...)

theriddick commented on 2025-04-03 10:13 (UTC) (edited on 2025-04-03 10:20 (UTC) by theriddick)

a821 For that iGPU you may need specific environmental settings or some additional driver component. For Ray Tracing under Vulkan that is.

Btw that png file exists where it should be.

openat(AT_FDCWD, "../assets/textures/Vulkan.png", O_RDONLY) = -1 ENOENT (No such file or directory)

Thanks, that looks like a clue.

FWIW, I compiled it on my work notebook using the vcpkg_linux.sh and build_linux.sh scripts, and then cd build/linux/bin && ./RayTracer ... and also fails with a different error :(

@a821

Here is the strace output, pretty big.

Thanks for testing.

I just checked that it build but didn't actually run it. There's probably an icon missing. but it's hard to say what's wrong without looking at the code, maybe you could strace it? I can have a look later today, or if you can figure a fix let me know.

It compiled and installed correctly but outputs this when ran with and without arguments. 

❯ /opt/raytracinginvulkan/bin/RayTracer --benchmark --width 1920 --height 1080 --scene 1 --next-scenes --present-mode 0

@theriddick

I get the same error with the latest imgui-1.19.9b ("OR" "OR" argument). I initially tried with 1.19.6, which seemed to work so I used that. I arranged the PKGBUILD so it builds imgui statically to be independent of the aur package. Also, the imgui-full package does not build with freetype support which is needed.

Here is the test PKGBUILD and the patch (the file should be called imgui-cmake.patch). I just checked that it builds in a clean chroot. It would be great if you can actually test the software.
