neoengine compiler error

please help me guys! why am I getting this error when compiling a "copy and paste" of first tutorial of neoengine?!?!? a start a new win32 console project. then insert a new main.cpp, copy and paste all lines of first neoengine''s tutorial. I already build the whole engine workspace. what I have to do to start a new app using the engine?
