I am using static OpenCV 3.0 libraries with Qt 5.4. I am having compilation errors about cv::displayOverlay():
OpenCV Error: The function/feature is not implemented (The library is compiled without QT support) in displayOverlay, file C:\Programs\opencv\sources\modules\highgui\src\window.cpp, line 446 terminate called after throwing an instance of 'cv::Exception' what(): C:\Programs\opencv\sources\modules\highgui\src\window.cpp:446: error: (-213) The library is compiled without QT support in function displayOverlay
and
undefined reference to `_imp___ZN7QWidgetD2Ev'
Could it be that I am missing a static library? As a note, I compiled OpenCV myself and have made sure that WITH_QT was checked. I have no problems when using the dynamic libraries.
