Hello there,
thank you both for the guide and the advices...greatly appreciated!
However, I'm still in trouble since I cannot get my GPU working with OpenCL:
I followed all the steps in this tutorial, but when I run clinfo it returns that the only
available device is my Intel Core i7-4712MQ CPU, and the HD4600 iGPU is not given.
My system is a Linux Mint 17 workstation with 3.16.0-38-generic kernel, rebuilt for the 3.15/16 kernel issues,

and with the register whitelist patch applied.


I had intel SDK installed, and that was the error..I uninstalled it and now clinfo says that libOpenCL.so.1 is missing (however I have plenty of libOpenCL in /etc/alternatives or /usr/lib/i386-linux-gnu or /usr/lib/x86_64-linux-gnu)...


Many thanks in advance, any help would be appreciated!
Stefano
