Build Error in the "refclock.h" header file, a part of Windows platform SDK

Question

I am building a VC++ solution & using Win& SDK & Win8 SDK (including these paths in LIB & INCLUDE settings of VS2008). But I am getting the following build error in refclock.h header file. I don't understand how can we get the error in a standard MSFT header file. Can anyone kindly help me in getting this fixed?

Answer 1

It's caused by an error in the refclock.h header and the order your include directories are specified in Visual Studio.

You need to have the BaseClasses directory (Samples/Multimedia/DirectShow) before the SDK include directory, since they both have a schedule.h file and refclock.h uses <> not "" for the include.
