Ah... Figure 6(a) and (b) are both .cpp files. You can put them in separate files, or just merge them into one large .cpp file. To compile, you need to add a "-I" include option for finding the OpenCL include files. To link, you need to add a reference to the OpenCL library.

The example does not have a ".cl" file because it would then have to be read into a string (char *) for clLoadProgramWithSource(), using for example oclLoadProgSource()--which is not part of OpenCL. Instead, the kernel code is set as a string, which is passed to clLoadProgramWithSource(). There is also a bunch of code in Figure 6(b) in an "#else ... #endif" block. That code is for reading binary from a hacked version of the CLCC OpenCL compiler, but I don't use in this example. For clarity, I removed that stuff, and combined the code like I said. I'll updated the blog to contain a link to a MSVC Project to make it easier to build.
