Fedora 18 and cycles

for enable the gpu rendering it’s necessary that i compile blender from the source? if this is correct i need to install cuda toolkit and build it following this metod http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Linux/Fedora/Scons? or there exist other way to do this.

What version of blender ?
Have you a compatible graphics card and latest drivers ?

I recently tried Ubuntu, and I had to use bumblebee to get the nvidia drivers. I still have to get the Cuda set up as well, and without it I can’t get Blender to recognize my laptop’s graphics card.

edit: I was using the Blender from the linux download on blender.org, not building my own.

blender 2.65a (i’ve tried with the repositories version and the offical page), i have a nvidia gt 640 shader model 2.1, i’ve installed the akmod drivers (for avoid the problems with the kernel updates)

i’ve installed CUDA following this wiki http://fedoraproject.org/wiki/Cuda, i’ve only installed the cudatoolkit because when i tried to compile the gpucomputingsdk shows two errors, but now blender recognize my graphics card and the render with “cycles engine” works more faster in linux than in windows (in my case).
