ANSWERED custom kernel 4.5.2 and catalyst amd driver

Recommended Posts

Hello I'm new here, i experiment a little bit on funtoo and I admit the world of custom kernel is new for me 

My problem is during the install of catalyst driver 14-20 from the amd site on a custom 4.5.2 kernel.  I had build the header whith make headers_install and in first I had an issue that said version.h not found so I had copy the file in /lib/modules/4.5.2/build/include/linux/version.h but after this I had another issue :

furthermore I had read somthing I think about it on fedora (https://bluehatrecord.wordpress.com/2015/09/17/installing-the-proprietary-amd-catalyst-15-9-fglrx-15-201-driver-on-fedora-22-with-linux-kernel-4-1-6/)but the english is not my language and all this stuff  are news for me (kernel, funtoo, and graphical driver hack )
 
can someone help me ? 

ps: i'm not use to post on forums and with html sorry if they are no html balise.

Driver source code has to be modified a.k.a. patched because your trying to build it against a newer kernel than when it was written.

Its like a key that only works in one lock,if you change the lock(kernel version) or key(driver version) it no longer works.

This can also apply to the build tool chain, glibc,gcc,libtool,dep versions when building other software.

I let the developers determine the versions,write the patches, so it builds on my computer.

When there's a problem I can file a bug report.

Hello cardinal,

I'm not sure to understand; do you purpose to file a bug report for my case ? 

if i understand well, my answer is I don't know !! how long is in general the time for the dev to make a patch like that ?

and i'm not sure it 's really important i just need the catalyst for virtualgl.
I try to make it work with an app server on xen or kvm and the graphics with virtualgl on the dom0 
I had yet make it work with a xen serv and an ssh connexion with a virtualgl machine and another ssh connection with a thin client (little tricky i know :D ) i'd like to know if its possible to do work 2 or 3  minecraft client with one hd7970 i don't need, i think the last kernel for that

 

have fun !
