Compiling hashcat: -I doesn't detect GPU

[james79]

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.
