GPU and Cuda

I'm trying to use gpu functions in my code but it seems something has gone wrong. I followed all the instructions out there that's related to setting up the gpu. Cmake recognized my cuda graphics card and I compiled all libs and bins including the new gpu dll which came to about 1.5gb. The strange thing is that when I use the getCudaEnabledDeviceCount() it returns a -1 value, which I'm not sure what it stands for. But I guess its not right. And of course when I use any other gpu related function it crashes the program. I'm using Visual Studio 2005, OpenCV 2.45, on Windows XP x64.

Does anyone know if there is a compatibility issue between Visual Studio 2005 and Cuda?

Looking at the sourcecode I found out

 if (error == cudaErrorInsufficientDriver) { return -1; }

Which means your CUDA version is not high enough for the OpenCV version you want to build! Update your CUDA runtime libraries! AFAIK, 2.4.5 requires CUDA 4.1!

Thanks, I'm using 4.2. but I think it might be a graphics driver issue. I'm going to try to update. Its might effecting the runtime.

It is indeed a driver mistake, it clearly shows from the error. Try updating or reverting to 4.1!
