Thanks for that. I went ahead and compiled the bleeding-jumbo from GitHub. Unfortunately I am getting the same error, line 782 now.

The first attempt output:

Build log:
ptxas info		: 0 bytes gem
ptxas info		: Compiling entry function ‘derive_key for ‘sm_30’
ptxas info		: Function properties for derive_key
ptxas 		. 	176 bytes stack frame, 12 bytes spill stores, 12 bytes spill loads
ptxas info		: Used 63 registers, 344 bytes cmem[0], 8 bytes cmem[2]

This output happened only once. I toggled the sm_30 line in john.conf with no change

The NVIDIA_CUDA env variable was not set so I looked and  found 4 different versions on my system and set the path for the cuda version from the cuda toolkit, then tried the driver version. I did not try the mesa or Intel version. I set it for /opt/cuda/lib64/libOpenCL.so, thinking the include would be found but I’m unsure about that. They were not in the same directory. 

Any idea how I should proceed?

Thanks

Bill
