You are probably missing the opencl-headers package on Ubuntu, because it works fine for me on Arch. You are right about the debug build being broken, though. I've just fixed that in e2369ed24e07b893beb5ccf755986594af2e8651.

After that commit both the "real" version and the debug version work fine on my system.

Indeed, after installing opencl-headers, I was able to run make and run vramfs. Working now, thanks.
