Use cuda function in cpp file

Question

How do I use CUDA function in a cpp file?

I must use a CUDA function declared in "cuda.h" (or other cuda libraries), for example cudaMalloc. I know it is simple to do in .cu files but my project is extended, we decide call some CUDA functions in .cpp files.

I saw in the SDK some CUDA functions are called from main.cpp, so why is it not working for me? How do I configure CUDA with Visual Studio 2010?

The error is:

cudaMalloc identifier not found

and

undeclared identifier for size_t types

I've tried to clean up your question a bit to make it more readable, hopefully I understood correctly but please add more information if not. — Tom, Sep 14 '12 at 11:46

You can call CUDA API calls from C/C++ compiled with cl.exe, just make sure you include the cuda.h header and link with cudart.lib.

For more detailed instructions on setting up Visual Studio 2010, see this answer.

I created my first cuda project following this link. Also, you need to include not only #include <cuda.h> but also #include<cuda_runtime.h>.
