OpenCV for Android with QTCreator
Solved
Qt Creator and other tools
-
Hi, i am using QtCreator for build a simple app for android using OpenCV. The code compile succesfully only when there aren't OpenCV object. When i add a simple cv::Mat it fails with a lot of error of type "the vtable symbol may be undefined because the class is missing its key function" this is my .pro file:
