OpenCL installation on Linux

[itanon]

Plus I'm starting to realize(reading on the web) that openCL seems to not to work properly on linux, but maybe I got wrong

You got that wrong.

You'll likely have much better luck switching to Ubuntu LTS.

I've tried to install all the openCL versions available(including the one for Ubuntu) but although the installations starts it warns me with:
"unsupported os detected..." And this happened either with the Ubuntu version as well as the rhel and sles versions....Maybe The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) is not supported at all but that's pretty strange since it's basically a Debian distro....
