I was not able to compile with 19 gpu's, i've got a lot of errors. 16 gpu's version compiled without any troubles.
I htink tpruvot must check this situation.

You need to modify 2 more files...... check here....
https://github.com/tpruvot/ccminer/pull/54It build without any error for me..... But i don't have 19 GPU rig to test....

Please try and let us know.
Thanks, just compiled x32 x64 versions without any troubles.
But haven't tested yet< because i have removed cards from rig.
Ccminer is very unstable with 19 gpu's and die very fast on lyra2z and skein algo, so ccminer is not usable with 19gpu's. I think only tpruvot can find solution(((
Strange thing, but on both algos miner dies on gpu0 but in case when i am using 16 gpu config, there is no troubles with gpu0 on ccminer x64 ver and x32 ver have different gpu troubels. In my situration gpu0 is p104-100

Tried zm miner 0.5.8 it is awesome and works well. Tried ewbf cuda miner it is peace of shit.
