libvulkan.so.1 seems to be missing?

[Svetomech]

I get this error when trying to run the binary (either by itself or using a vkquake-launch.sh wrapper): error while loading shared libraries: libvulkan.so.1: cannot open shared object file: No such file or directory

I googled the error. Most answers say I must have VulkanSDK installed. Is that correct? I thought that a Vulkan-supported videocard w/ updated drivers are enough to run the game.

This is what I have:

Ok, I may have missed adding that lib. I will check the libs folder for the library.

[Svetomech]

Don't. It is present, but doesn't seem to load properly.

[mdeguzis]

Can you please provide your Linux distirubtion details? I can try to reproduce the error when I get home in a few hours. It's possible I made a mistake somewhere.

[Svetomech]

My distro is Linux Mint 18.

Also, I got the libraries to load (export was behaving weird for some reason), but now all I get is an uninformative Segmentation fault.

Should I create a separate issue for this? I would, but it seems like I've been doing this too much recently :)

[mdeguzis]

I tried ./vkquake-launch on my Debian VPS, and it loads up until the point where it is trying to load the WAD files. I will setup a VM later this evening for Mint to reproduce. If this does not work for you in the end, I will host vkquake on my PPA here: https://launchpad.net/~mdeguzis/+archive/ubuntu/libregeek-games . The owner here does not wish to support/provide distro packages.

[Svetomech]

Hmm, I think I know what is the problem here. I downloaded vulkan-utils package and ran vulkaninfo: Cannot create Vulkan instance. /build/vulkan-1P8eOh/vulkan-1.0.8.0+dfsg1/demos/vulkaninfo.c:633: failed with VK_ERROR_INCOMPATIBLE_DRIVER

So, what driver are you using exactly on your Debian VPS? Compatibility page says Mesa is supported, but vulkaninfo says otherwise, it seems. Do I have to pull it from some PPA and not from official repositories?

[mdeguzis]

You need to check your driver version with lspci -v. You could also check http://vulkan.gpuinfo.org/ for more. I often will tell people to check their driver against the release notes page, or the manufacturers listing as well. For instance, Nvidia has a page such as: https://developer.nvidia.com/vulkan-driver

[Svetomech]

I've installed latest Mesa drivers from here. vulkaninfo output is now diferrent: stdout.txt, stderr.txt

Here is info for my device from the site you mentioned:

vkQuake still gives me a Segmentation fault.

[Novum]

This is not the official "my driver installation is broken" support page. This has nothing to do with vkQuake.

[Svetomech]

Segmentation fault might not be related to that (I tried some other Vulkan demos, like vkcube - they do work). But okay, you're the repo owner, you can close the issue regardless of its ‌state.

[Novum]

Please report to Intel, the seg fault is 99% likely a driver bug.

[Svetomech]

Okay.

[Svetomech]

Wait. I installed vkQuake from the PPA given by @mtdeguzis and now seg fault is no more.

Where should I put game files? Is there a command line parameter to set a base directory?

[mdeguzis]

@Svetomech , since you are not using a hand-compiled version here, this is outside the scope of this issue. Feel free to contact me via libregeek.org or LaunchPad. It is not Novum's court now that you are using a different installation method.

[Svetomech]

to contact me via libregeek.org or LaunchPad

Didn't even know it is possible w/ the latter and never heard of the former. But okay, sure.

@Novum, sorry for all the inconvenience.
