missing ap_int.h

[ahamilton57]

Following instructions for building IDCT example, I have a build issue:

$ make run TARGET=sw_emu

Same issue. How did you resolve it?

Your issue is most likely due to the fact that the ap_int.h file is not in your g++ include path.

Which version of the Xilinx tools are you using?
What is the XILINX_VIVADO env var set to?
