libvulkan on macOS not found

[def-]

I have libvulkan in /opt/homebrew/opt/vulkan-loader/lib/, but still seeing:

[2025-01-02T16:41:08Z INFO  graphics_backend::backend_thread] graphics backend thread exited: dlopen(libvulkan.dylib, 0x0005): tried: 'libvulkan.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibvulkan.dylib' (no such file), '/usr/lib/libvulkan.dylib' (no such file, not in dyld cache), 'libvulkan.dylib' (no such file)

Ah thanks for trying, macos defs needs some love, since I cannot test it.

ash has a feature called linked (https://docs.rs/crate/ash/latest/features)
Maybe we'd need to enable that for macos, since I assume this libvulkan.dylib comes from your brew installation anyway?

If you want to try out
ash = { version = "0.38.0", features = ["linked"] }
lib/graphics-backend/Cargo.toml

Else they also mention macos here:

Works by manually putting libMoltenVK.dylib as libvulkan.dylib next to ddnet-rs

After ~2 seconds of seeing the menu I get a pink screen.

In the logs one time is UTC, the other localtime:

Mh ok, since vulkan support wasn't great on ddnet either for macos, maybe we hit some weirdness of moltenvk again.

Generally a WGPU backend is planned which would have native metal support

https://github.com/KhronosGroup/MoltenVK/issues/2220 sound very related. If you can easily downgrade, maybe worth a try

If you do brew install molten-vk you get a libMoltenVK.dylib alias instead of libvulkan.dylib at /opt/homebrew/lib/ so i think the app should also try searching libMoltenVK.dylib

Sadly i also get the pink screen with both local build and CI build

Does

brew install [email protected]

not work on macOS?

The issue I mentioned tells that earlier versions worked correctly.
Besides that on ddnet we also have other issues with molten-vk, so it's not said this will help

[M0REKZ]

brew:
Warning: No available formula with the name "[email protected]". Did you mean molten-vk?

Downloaded MoltenVK 1.2.6 from https://github.com/KhronosGroup/MoltenVK/releases/tag/v1.2.6 and renamed to libvulkan.dylib, seems to work, i get mouse stuck when pausing in game (esc key) so i need to kill the app xD

I hope I fixed that with #62 by making the grab modes have a fallback since macOS does not support confined cursors with winit apparently
