Trouble running FLACCL under linux on Optimus laptop, no opencl platforms found Options

[skamp]

I tried running FLACCL and FlaCuda under linux on a Optimus laptop (NVIDIA GT 555M not connected to any display, plus Intel HD 3000 chip integrated in the Sandy Bridge CPU), but I can't seem to make it work. My understanding is that I need to use Bumblebee in order to make use of my NVIDIA GPU. I've tried the following:

CODE

optirun ./CUETools.FLACCL.cmd.exe --opencl-type GPU --opencl-platform 'nvidia' foo.wav
optirun ./CUETools.FLACCL.cmd.exe --opencl-type GPU --opencl-platform 'NVIDIA' foo.wav
optirun ./CUETools.FLACCL.cmd.exe --opencl-type GPU --opencl-platform 'NVIDIA CUDA' foo.wav

I get:

Error     : no opencl platforms found

Same with FlaCuda:

Error     : Exception of type 'GASS.CUDA.CUDAException' was thrown.

I made sure in the latter case to install the linux version of CUDA.NET.dll.

I have libOpenCL.so and libcuda.so installed. Am I missing something?

[Gregory S. Chudo...]

I'm afraid i don't know much about Bumblebee.
Try omitting --opencl-platform 'NVIDIA CUDA' parameter, so that it will try to use the first available platform. Bumblebee might have a different name for opencl platform.
Or it might be that you don't have an opencl driver installed. Have you tried running opencl samples from nvidia?
Take a look here: http://samiux.blogspot.com/2011/05/howto-n...-on-ubuntu.html

I installed the CUDA toolkit and ran the sample CUDA code as instructed on that blog.

Then I tried running FlaCuda and FlacCL without --opencl-platform but I got the same result. I'm sure it's something silly, there's no good reason your apps can't run on my setup.

need compile wine with opencl support

if use archlinux (i look you first post, the link is archwiki, i suposed uses this distro, like me xd) install libcl, opencl-headers, and lib32-nvidia-utils. and build wine from the GIT
