Wrong ELF class

Hi,

I’ve started learning Vulkan very recently and I came across a problem. I set up validation layers buy they are giving me errors:

    Validation layers: /opt/amdgpu-pro/lib/i386-linux-gnu/amdvlk32.so: wrong ELF class: ELFCLASS32
    Validation layers: /usr/lib/i386-linux-gnu/libvulkan_intel.so: wrong ELF class: ELFCLASS32
    Validation layers: /usr/lib/i386-linux-gnu/libvulkan_radeon.so: wrong ELF class: ELFCLASS32

Graphics driver seems to use for some reasons 32bit versions of Vulkan libraries. I tried to find solve the problem by googling it, but couldn’t find an answer.
Would you mind helping me with that?

Thanks.
