Cannot find libOpenCL.so in CUDA toolkit 4

I’ve downloaded the CUDA Toolkit 4.0 and the GPU Computing SDK but I cannot find the required libOpenCL.so to compile my program.
Any idea where is located?
thx.

The libOpenCL.so is packed in Nvidia driver not CUDA Toolkit or GPU Computing SDK. If the driver has been installed successfully, you should have it.

First go to C:\Documents and Settings\All Users\Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK x.x\OpenCL\common

then double click on oclUtils_vcX and then build it. You’ll have the OpenCL.lib in: …\All Users\Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK x.x\OpenCL\common\lib\Win32

Linux has no C:\Documents and Settings External Image

Ohh, I see. External Image
