Microsoft Visual Studio finds errors with all of my CUDA device-side functions

I was wondering if anyone can help with this error I'm getting in Cuda code. I want to define the function but it's saying that this declaration has no storage class or type specifier. Anyone know what should I do? This is a link to the screenshot of the error.

As @RobertCrovella explains, this is just your IDE not being aware of CUDA keywords when parsing your source.

Something you could do is make your parser find a

#define __device__

line, which would make it stop complaining. The problem is, you want the CUDA compiler not to hit this #define. So you can put it within an #ifdef, like so:

#ifdef __CUDACC__
#define __device__
#endif

which does the trick.

Of course, this only handles one keyword, __device__. You would need to have similar definitions for all CUDA keywords, as well as types and functions which are implicitly defined.
