usr/bin/opencl directory missing abort
hashcat aborts with a core dump and at the top in red is usr/bin/opencl directory not found

however if i try to trick hashcat by going to the usr/bin and make new folder named opencl then i get some like mem too small.

if it is that i need the opencl drivers where can i get them?

or  is the geforce 8500 gt 512 meg too legacy and i need something like tesla?

what is the usr/bin/opencl is that a folder or a binary?

can i simply copy the binary from another install like The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) and set the permissions to execute?
