[Mesa-dev] Error when trying to compile RADV

[Jakub Hlusička]

I ended up having to use `env LLVM_CONFIG=llvm-config-3.9` in order to 
get it to compile. After installing it, I think it loaded up properly. 
I couldn't get Vulkan examples ( 
https://github.com/SaschaWillems/Vulkan ) to work, though; it was 
saying "Unsupported driver". So I played around the files, trying to 
get it work, rebooted the system and found out I had broken it 
completely, because the login screen didn't even show up. I guess I'll 
just wait for the "official" RADV release. Oh, well.

Thanks,
Jakub "Limeth" Hlusička
