Simple OpenCV command works in Debug mode but not Release mode

Question

I am trying to load in a training xml file with CascadeClassifier::load(), and it works just fine in Debug mode, but in Release mode I get a runtime error.

Answer 1

make sure you're linking to openCV's release dlls when running in release mode. I've had similar problems when I tried to load files with mixed release and debug dlls.
