Failed to Load Kernel

[Gabriel-Grechuk]

I'm trying to run the OpenCl version because my computer can't run the CUDA one. Same issue #31
but when I try to run Bitcracker it gives me an error Failed to load kernel. after Dictionary attack

here is the complete log

Words error... exit!

I'm using Arch Linux, the CUDA and OpenCl are installed in /opt/cuda/; I fixed the Makefile and it compiles with no errors, but can't run 😔

请尝试再bitcracker根目录下执行 bitcracker_opencl
例如：./build/bitcracker_opencl
不要再build中执行程序

Not sure how helpful this will be but this seems to be related to line 55 of the w_blocks.c file for OpenCL where it tries to get a file handle to the path: "./src_OpenCL/kernel_wblocks.cl" since this seems to be a relative path perhaps when running the executable it is unable to find the kernel cl file? I'd try running the command from the bitcracker-master directory and see if that helps.

E.G.
./build/bitcracker_opencl -f has_recv_pass.txt -d passwords.txt -t 1 -b 1 -g 0 -r
