Mac M1 Pro Sys_Error: VKimp_Init() - could not load Vulkan subsystem

[CliveRosfield]

I've tried for days now and keep getting this error when launching quake3e with Vulkan. I'm not sure what the issue is as I've tried to install Molten-vk with home-brew and Vulkan sdk, I've tried version 3.216.0 as well as 3.224.1. As for more information, I had also installed SDL2 first without home-brew and got the error about sdl.h when attempting to build with make, so I fixed that by editing the make file and putting "BASE_CFLAGS += -I/opt/homebrew/include/SDL2 -D_THREAD_SAFE" and "CLIENT_LDFLAGS = -F/Library/Frameworks -L/opt/homebrew/lib -lSDL2"..... anyways I don't know a lot about this kind of stuff. I managed to get the OpenGL version to work but I'd prefer the Vulkan one if someone could please help. Sorry if this is messy im not very experienced with this, I just wanna play this awesome quake 3 port on my M1 PRO.......edit: Also I wanted say I ran make using commands mentioned by tomgreen66 inside issue #176 that should've fixed the problem with the recent changes of Vulkan 3.216.0, but I still get the same error about not loading Vulcan subsystem when running the created binaries.

Did you find a solution? I am about to try the same on My Mac Pro M1 as well.

No I never figured it out. If it works for you let me know. I'm running Ventura though, so that alone could be the problem im having.

Try with r_fullscreen 0

I'm getting this same error, although slightly different output.

Here's what it looks like with r_fullscreen 0 and r_modeFullscreen "-2". Here's my q3config.cfg file: q3config.cfg.zip

Sys_Error: VKimp_Init() - could not load Vulkan subsystem

EDIT: oh and I built the binary with: make USE_VULKAN=1 RENDERER_DEFAULT=vulkan USE_RENDERER_DLOPEN=0 -j 8

The good news is the opengl renderer still works (although not opengl2).

[Pan7]

After getting the error "VKimp_Init() - could not load Vulkan subsystem" and using the start parameter "+set fs_debug 1" it showed me an error about the missing file "vulkan-1.dll". Downloading the runtime component for Vulkan solved the problem and Quake3e runs now with the Vulkan renderer (set cl_renderer "vulkan").

export DYLD_LIBRARY_PATH=`brew --prefix molten-vk`/lib

export DYLD_LIBRARY_PATH=`brew --prefix molten-vk`/lib

Thanks @ph1lm!! That worked!!
