Hi. Today I'm trying to compile OpenCV on a Windows Xp machine with mingw32. At the 91% of the process I obtain this error:

you do not need to compile, you can just download the .exe of opencv from http://opencv.org/downloads.html and run it.

I have tried that package but my program goes to crash on startup. Using the libraries compiled from myself my program works well. The program is based on Qt 5.1 (mingw).

@Pinky : The prebuilt libraries won't work with QT, they are built without that option so for QT support you need to build the openCV library yourself.

@Denis Gottardello : make sure that you are building the openCV 2.4 branch if you retrieve the sourcecode from GIT and not the master branch. Master branch is most of the time unstable and cannot guarantee that build will finalize completely.
