xf_resize fails compiling on HLS

[Q-point]

I tried to use a standalone compilation of resize, Gaussian, erode using HLS.

Only erode passes:

@Q-point ,

Do not use the flag "-std=c++0x" for Synthesis, when using Vivado HLS in Windows OS. It is mentioned as a note in HLS use model guide.

@bgouthamb

OK, thanks. Synthesis passes when I remove the flag "-std=c++0x". Curiously enough the same flag works with the dilation core with no problem on Windows 10.

Hi bgaouthamb, I 'm facing the same issue. But on removing the "-std=c++0x" although the original errors are resolved, I'm facing a "C preprocesor failed" error as shown below : -

Any idea as to what might be the reason ?Thanks, Nitin
