Subject: Re: problem with john-cuda and osx
hi,
thx for help, but which newly compiled version (macos-x86-64-opencl i get:
$ ./john --format=wpapsk-opencl --test
OpenCL platform 0: Apple, 2 device(s).
Using device 1: GeForce 8800 GT
Compilation log: Error getting function data from server
Error building kernel. Returned build code: -11. DEVICE_INFO=130
btw, i followed some tutorial about compiling john with multicore abilities enabled by editing "makefile" in src folder.
However, the files isn't there, do i have to make it somehow?
thanks in advance!
