I'm hoping to help, but I'm not sure I understand the problem here.
CUDA is Nvidia's proprietary compute library for utilizing Nvidia's GPUs, AMD takes an open source approach with their graphics cards by using OpenCL.
Are you trying to use CUDA on an AMD card? If so it won't work.
I don't think so. Just running ./ethminer by default gives this message
Gotcha.
If you have a shell or bash script, try adding the arguments: -X --opencl-devices 0,1,2,3.
You may need to alternate the numbers to the corresponding indices of the graphics cards.
Thanks, got it to work with that
How do I do it in Windows?
I have an AMD R7 360 and the same problem happens to me.
