I am using Visual Studio 2010 environment and am trying to accelerate some of my previously written OpenCV algorithms with the help of CUDA. I have a separate .cu file that compiles fine individually in Visual Studio and my .cpp file also compiles fine individually.
But when I try to build the solution that contains both of these files I get an error as below:
error LNK2019: unresolved external symbol "void __cdecl ComputeBasisKernelWrapper(float *,float *,float *,float *,float *,float *,float *,float *,float *,int,int)"
ComputeBasisKernelWrapper is a function that is defined using extern "C" in the .cu file and is responsible for making the necessary CUDA allocations and carrying out parallel computations.
I have a similar framework that works fine where I use a non object-oriented .c file that makes calls to functions in a .cu file.
So, I am not sure whether I need to make some changes in the compilation settings or if something else is the issue.
Any help is appreciated.
