How to integrate OpenCL with Visual Studio 2008 help needed

Accelerated Computing CUDA CUDA Programming and Performance

Hi,

Is there any tutorial presenting how to integrate openCL with Visual Studio??

I’ve tried lots of stuff to do, but nothing helped me. I’ve installed cudatoolkit and gpu computing sdk properly, cause all the tutorials includd works.

i’ve set system variables :

$OPENCL_INC - pointing to

C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK\OpenCL\common\inc;C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK\shared\inc

and

$OPENCL_LIB - pointing to

C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK\OpenCL\common\lib;C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK\OpenCL\common\lib\Win32;C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK\shared\lib

in visual studio i’ve set in tools->options->project directories

on Includes and Liblaries appropriate system paths

and with a simple code :

[codebox]include

include <Cl/opencl.h>

include <oclUtils.h>

int main(int argc, char *argv) {

cl_int err;

cl_platform_id pl;

err = oclGetPlatformID(&pl);

std::cout<<err<<std:endl;

return 0;

}[/codebox]

all i get is multiple errors :

and so on

where is there a problem

can anyone help me ??

try to open in the SDK the project on VectorAdd for example and just take the same options

The main problem is incorporating all the libraries and header files into your project. I believe the easiest solution is to open one of Nvidia’s projects and work from there, as jonathan81 has suggested. Merely make a copy of one of the projects, such as oclVectorAdd, and play around with it. In Project Settings, I was even able to change it from a console into a windows application. However, if you wish to create your own project from scratch, for whatever absurd reason it is, you should be able to find appropriate instructions in the ‘OpenCL SDK Release Notes’ (it will tell you which header files and libraries are required to have your OpenCL program up and running).
