Linker Problems with Cublas Library (cannot open file 'cublas.lib')

I wrote some code to multiply some symmetrical matrices and decided to use CUDA (cublasSgemm) to do the work for me.

I've got the Toolkit, as well as everything else set up but run into a problem when I try to use the cublas functions.

I've included:

#include <cuda_runtime.h>
#include "cublas_v2.h"

And I've also gone to Properties>Linker>Input and added cublas.lib to the dependencies. When I get everything going, I hit this error:

LINK : fatal error LNK1104: cannot open file 'cublas.lib'

If I remove the library from my dependencies, I get unsolved errors for all of the cublas functions.

Any help would be wonderful... :).

So, the solution was simpler than I thought. Go to your project properties and make sure that you're running x64 rather than win32. The cublas lib file does not exist in the win32 library folder.
