    AMD APU OpenCl Error

    I installed the AMD APP SDK and get an odd error when i run oclhashcat

    root@kali:~# oclhashcat+ -m 0 098f6bcd4621d373cade4e832627b4f6 --force
    /usr/bin/oclhashcat+: line 3: 4467 Segmentation fault ./oclHashcat-plus.bin "$@"

    and if I run clinfo I get

    root@kali:~# clinfo
    Segmentation fault

    Does anyone have recent guide to setup opencl?

    which version of amd app sdk did you install? how did you install amd graphic drivers? probably it is a missmatching between drivers and sdk. i am still running into installing amd latest drivers on a desktop apu.

    The version I have installed is the one installed by this guide . The versrion of the APP SDK is AMD-APP-SDK-v2.8.1.0-lnx64. What version Should I have for the driver version. I do know the version in the repos is before version 13.
