[linux] Vulkan API back-end does not works - Shished - 10-05-2016

I'm compiling dolphin from source for myself and Vulkan API has never worked for me since the PR merge.
After pressing Play button emulator silently crashes. Here is the terminal output:

Code:

Aborted (core dumped)

GDB reveals more info about the crash:

Code:

Thread 11 "Emuthread - Sta" received signal SIGSEGV, Segmentation fault.

GDB Backtrace:

I tested earlier revisions from the separate repo (before the PR merge) and it worked. Latest revision from that repo also does not works.
Vulkan API demos and games (Talos Principle and Dota 2) works fine. Only Dolphin has such problem.

My OS and PC specs:

OS: openSUSE Tumbleweed x86_64 (linux 4.7.5)
GPU: Nvidia GTX 660 (proprietary driver version 370.28)
CPU: Intel Core i5-3570K
RAM: 12GB

Run "vulkaninfo" in terminal. The output should list an API version. What does it show?

Edit: It's probably due to you having an older version. When I was on 1.0.8 dolphin would crash, but other demos would work. When I updated to 1.0.21 dolphin worked.

Looks like my installation was messed up and after some cleanup vulkaninfo reports API version 1.0.26 and dolphin-emu works now. Thanks!
