ofxOpenCV different behavior on Mac and Windows (VS 2008)

Hi Guys, I’m working on a project on my mac that needs to ultimately run on a windows.
I am using cvCalcOpticalFlowBM(), and on windows I get a rather cryptic error message talking about wrong input dimensions (“sizes of input arguments do not match”), while on the mac it runs smooth. I debugged on both platforms to confirm that the values passed to cvCalcOpticalFlowBM() were identical, so it’s the cvCalcOpticalFlowBM()'s implementation that must be different on both platforms.

I would be really surprised, but is it possible that the mac and vs_2008 versions of the libs included in ofxOpenCV are compiled from different versions of the OpenCV source? I see all the platforms share the same headers (openCV version 1.1.0), so all the compiled libs should be the same version too, right?

I am using the latest revision of ofxOpenCV from github…

Thinking about rebuilding openCV myself to create the libs and see how it goes, but I’d like to confirm first…
