I am using Vivado 2016.3 for compiling the stable version of hdl (hdl_2016_r2). I have successfully generated the bitstream in vivado 2016.3. However when, I am trying to load the No-OS drivers for FMCDAQ2 from 2016_R2 branch into Xilinx SDK i am having problems. I have copied the drivers files into source folders in SDK as described. But i am having the following errors. Analog devices platform library even though do have the definitions of ad_printf, the SDK is not recognizing the header file. How do you compile the project without errors.
