I am trying to convert a cpp file to a .cu file . However the compiler is reporting errors for all the typedefs and static functions in cpp. It also does not detect the scope resolution operators and report errors for them as well.

CUDA makes some significant changes to the way preprocessor macros are expanded, as it runs the code through the preprocessor multiple times to expand the CUDA constructs and separate host and device code. This is likely to break large existing code bases.
My general strategy in this case (and even with newly written projects) has been to keep all the existing code in .cpp files and only move as little code into .cu files as possible. I just move the typedefs and defines that are needed in .cu files as well as .cpp files into separate headers, and write small wrapper functions around CUDA calls and kernel launches which I then call from the existing .cpp files.
