Julia Set - CUDA by example - help me set up the project - c

Question

I have been reading CUDA by Example by Jason Sanders and Edward Kandrot and have come across chapter 4 where they solve Julia Set using CUDA.
Also, there is a source code available on a books page; https://developer.nvidia.com/content/cuda-example-introduction-general-purpose-gpu-programming-0
When I try to include all the files necessary for the project (all header files and .cu ones) it won't compile.
My usual CUDA projects that I create from scratch work without problems (VS 2010, CUDA 5.0).
Did anyone had the same problem and can you please specify each step in order to make this Julia Set set up as it should be?
P.S. Here is a code that won't work in header file:

Line that is making a first error is :
PFNGLBINDBUFFERARBPROC glBindBuffer = NULL;
VS says: IntelliSense: PCH warning: header stop cannot be in a macro or #if block. An intellisense PCH file was not generated.
thank you very much

Answer 1

to run it properly you have to first download the source codes from :`CUDA by Example source code
then extract it. when you create your project in visual studio, if it is 2010 and newer you should go to the project properties and go to VC++ Directories and add the extracted folder as an include path. also add the lib folder as library path and the bin as the executable path.
then you can add a new cu file to your project and copy the content of the chapter 4 folder -which ever file you want from that- and paste it there and compile it.
if still it doesn't compile, you should go to project properties -> linker and find the "Additional Dependency" and add cudart.lib and you are all set.
also pay attention that the include phrases in the books code are like this: /.../common/book.h , you should change them to common/book.h format.
