Compiling hashcat: -I doesn't detect GPU - james79 - 08-18-2018
Hello,
I'm running hashcat compiled from source on Debian 9.1 Stretch.
I've got an instance with Intel Xeon CPUs and an NVIDIA Tesla P100 GPU. This is the output of nvidia-smi:

This is what I get from ./hashcat -I

I'm not sure how to get hashcat to detect and use the NVIDIA Tesla P100 GPU. I have cuda installed, the OpenCL runtime, and the nvidia drivers. I thought this would work.
Does anyone have hashcat running on Debian 9.1 with NVIDIA GPUs and how did you get hashcat going?
I installed hashcat from deb repo too, and it installed a few other things. Now hashcat -I detects a second platform but no extra device. When I try to run hashcat, I get clGetDeviceIDs(): CL_DEVICE_NOT_FOUND.
Thanks for any help/pointers.
Maybe I should terminate the instance and install with Ubuntu. It seems to be better supported.

D'oh. Found answer to my question:

I also created the instance with Ubuntu 16.04LTS instead of Debian 9.1.
