AD9371 CORE_BASEADDR ?

I rebuilt the AD project using 2018.2 (which is listed as the latest supported Xilinx release) and posted the project here:

The problem is that AXI_AD9371_CORE_BASEADDR is undefined.  If I define it, the program compiles.

 

What is AXI_AD9371_CORE_BASEADDR?  Why is it missing from the project?

Thanks,

Ray
