How can i use OpenCV 3.0 pre-build in windows with Qt 5.5?
Hi and welcome to devnet,
The first thing to do is verify that the compiler used to build OpenCV matches the one used for Qt.
As for using OpenCV and Qt together, please search this forum, it's a question that has been asked and answered many times already.
