Hello !

I encountered the following compile errors when build calcOpticalFlowFarneback example (farneback_optical_flow.cpp).

however I have no idea where's the errors come from. does anyone know why ?

I just guess major errors are "saturate_cast : __forceinline not permitted ~" and "C++ asm syntax ignored ~", and something might not be included in the project.

  • with opencv 2.4.8, VS 2012

thanks in advance !

Best Regards, yeonchool

How did you build this example? Did you build it as a part of OpenCV project or you added farneback_optical_flow.cpp to your project? Did you modify this source? opencv2\gpu\device\saturate_cast.hpp header can be used only in CUDA code that compiles with NVCC, but farneback_optical_flow.cpp doesn't include this header.

I added and compiled it in my application. what headers should I add to compile it in my project ? or I cannot use the function without NVCC ?
