I spent about week+ looking into you and quasar84's fork of ccminer and both produce the exact same errors when trying to compile this in VS2013 with CUDA 7.5-8.0.
First I will state that I do not want to compile this in CUDA 9.0 As I don't have any nvidia cards of the 10xx variety, and I don't like that CUDA 9.0 depreciates older 2.x cards, making the software compiled very limited to the amount of graphics cards compatible.
You really should update that Readme file because even though it recommends CUDA 6.5 with 7.5 optional. Looking at the project file it clearly is set to go with CUDA 9.0 and changing it will produced tons of errors during compile.
