Subject: Unable to use OpenCL on arm64v8/debian stretch
When I run, as in README-OPENCL,
../run/john --test --format=wpapsk-opencl
../run/john --test --format=wpapsk-opencl --device=0
I see
Device 0@...i: Mali-T860
Benchmarking: wpapsk-opencl, WPA/WPA2/PMF/PMKID PSK [PBKDF2-SHA1 OpenCL]... OpenCL CL_INVALID_PROGRAM_EXECUTABLE (-45) error in opencl_wpapsk_fmt_plug.c:262 - Error creating kernel
What does the error mean and what can I do to eliminate it?
What I did follows.
I compiled and installed Rexgen.
I installed the following packages.
apt-get install ocl-icd-libopencl1 clinfo libopenmpi2 openmpi-bin argon2
The following additional packages will be installed:
libgfortran3 libhwloc-plugins libhwloc5 libibverbs1 openmpi-common
apt-get libssl-dev yasm libgmp-dev libpcap-dev libbz2-dev zlib1g-dev libopenmpi-dev openmpi-bin libgmpxx4ldbl libpcap0.8 libpcap0.8-dev libhwloc-dev libibverbs-dev libltdl-dev libnuma-dev opencl-c-headers libzip-dev libzip4
I have configured JtR resulting in the output below.
