I don't remember why, and I can't find a post saying why, but I'm still running 3.1.1. I decided to try out 3.4.2 and I get this:
ADL..................: SDK NOT found, GPU monitoring support DISABLED
from the exact same configure command I can still run in the 3.1.1 source and get this:
ADL..................: SDK found, GPU monitoring support enabled
. Any chance a change needs made in the source to fix that again? I know this happened once before and it was a pretty quick fix, after which I redownloaded.
Copy the ADL_SDK include files from 3.1.1 (or the sdk_app thingy) to the ADL_SDK directory and re-configure.
