Error building on Ubuntu 18.04

Hello,
When building these drivers on Ubuntu 18.04 with Kernel 4.15.0-65-generic I get the following error:

I tried adding cdev as the output requested, but that didn't fix this issue.
I ran ./configure the first time, and when that failed, I tried ./configure --without-memtrack --without-debug-info and run make and I still get the same result.
I have the linux-headers-4.15.0-65-generic and build-essential packages installed on the build system. Are there any other packages required for build?

Thanks,
Luke
