They recommend copying the adl headers to the /sgminer-gm/AMD_SDL folder. But they are still working on that part, doesn't work all that hot. Don't need it to mine. What kind of card do you have, and what's it hashing?
I have rx470 4g and claymore reads only 3g ram and 14 compute units (the card really is 4g and 32 compute units) so claymore automatically decrease mining speed to i 7 and the mining speed is truly low
