Did you change sometime in when link Path to OpenCV 3.2.0 library or change some where in source code, Attached images are some error I met when using OpenCV3.2.0 on qt creator. When I debug code. It show problem here " while (running) if (capture.read(image)) ". Beside, when I run using "Make all" command. It showed error as below. I have been trying to remove -lopencv_nonfree in "makefile" But it still not work.
