Question about NppGpuComputeCapability

Hi, All,

I am installing cuda tookit4.0 and it’s SDK, I install both of these two into /home/tookit/ directory, and trying to build the CUDA SDK, but I suffer the error “error: ‘NppGpuComputeCapability’ was not declared in this scope” in NVIDIA_GPU_Computing_SDK/CUDALibraries/src/freeImageInteropNPP/freeImageInteropNPP.cpp.

I checked that the NppGpuComputeCapability is defined in cuda/include/nppdefs.h and thus include this header file in freeImageInteropNPP.cpp file, but the error still shows up.

Does anyone know the answer and can give some hints?
