OpenCV on Windows Debug Mode
For some reason (I am not clear as to why), OpenCV seemingly did not work in debug mode with QT on Windows 7. I am running Windows 7 64-bit and I built the OpenCV libraries myself (in Visual Studio 2010). Unfortunately, it took me an unreasonable amount of time to discover that in Windows, if I want to run some of the OpenCV libraries in debug mode without everything blowing up in my face, I need not only the .dlls and the .libs, but also the .pdb files. Apparently, Windows uses these to run the libraries in debug mode. Once I figured this little piece of magic out (and Google did not offer a solution immediately), I just placed the libs, the dlls, and the pdbs in the same folder and told my program where this directory was when linking. Then, viola---it worked perfectly. Wish I had found out sooner.
