When I run the OpenCL 13.1 project on Visual Stdio 2012 on Terasic's DE5-Net board, the compilation error shows up: link : fatal error lnk1181: cannot open input file 'kernel32.lib'; no compilation error on Visual Stdio 2010.
Go into the Visual Studio linker settings and remove kernel32.lib from the library list. I'm guessing Microsoft removed that library or they moved it to a different location that isn't being referenced. This assumes you do not rely on anything that is contained in kernel32.lib
