Dear All,

I am trying to configure OpenCV 2.4.13 with Qt MinGW. The config with CMAKE was successful, however, when I try to build with mingw32-make command I get the following error:

C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window_QT.cpp:2539:9: note: in expansion of macro 'foreach' foreach (QAction a, centralWidget->vect_QActions) ^ C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtCore/qglobal.h:963:49: error: request for member 'control' in '_container_', which is of non-class type 'int' for (variable = *_container_.i; _container_.control; _container_.control = 0) ^ C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtCore/qglobal.h:971:21: note: in expansion of macro 'Q_FOREACH' # define foreach Q_FOREACH ^ C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window_QT.cpp:2539:9: note: in expansion of macro 'foreach' foreach (QAction *a, centralWidget->vect_QActions) ^ C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtCore/qglobal.h:963:70: error: request for member 'control' in '_container_', which is of non-class type 'int' for (variable = *_container_.i; _container_.control; _container_.control = 0) ^ C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtCore/qglobal.h:971:21: note: in expansion of macro 'Q_FOREACH' # define foreach Q_FOREACH ^ C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window_QT.cpp:2539:9: note: in expansion of macro 'foreach' foreach (QAction *a, centralWidget->vect_QActions) ^ C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window_QT.cpp: In member fun ction 'void DefaultViewPort::controlImagePosition()': C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window_QT.cpp:2748:21: error : ambiguous overload for 'operator=' (operand types are 'QTransform' and 'QTrans form') matrixWorld_inv = param_matrixWorld.inverted(); ^ In file included from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtGui/qimage.h:47:0, from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtGui/qpixmap.h:48, from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtGui/qicon.h:46, from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtWidgets/qabstractbu tton.h:43, from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtWidgets/qpushbutton .h:43, from C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtWidgets/QPushButton :1, from C:/opencv-2.4.13/opencv/sources/modules/highgui/src/window _QT.h:53, from C:\opencv-2.4.13\opencv\sources\modules\highgui\src\window _QT.cpp:47: C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtGui/qtransform.h:79:17: note: candidate: QTransform& QTransform::operator=(QTransform) QTransform &operator=(QTransform &&other) Q_DECL_NOTHROW // = default ^ C:/Qt/Qt5.7.0/5.7/mingw53_32/include/QtGui/qtransform.h:81:17: note: candidate: QTransform& QTransform::operator=(const QTransform&) QTransform &operator=(const QTransform &) Q_DECL_NOTHROW; // = default ^ modules\highgui\CMakeFiles\opencv_highgui.dir\build.make:193: recipe for target 'modules/highgui/CMakeFiles/opencv_highgui.dir/src/window_QT.cpp.obj' failed mingw32-make[2]: [modules/highgui/CMakeFiles/opencv_highgui.dir/src/window_Q T.cpp.obj] Error 1 CMakeFiles\Makefile2:2042: recipe for target 'modules/highgui/CMakeFiles/opencv_ highgui.dir/all' failed mingw32-make[1]: * [modules/highgui/CMakeFiles/opencv_highgui.dir/all] Error 2

Hey guys,

I found the major issue to this. When configuring opencv with mingw for Qt.5.x do not enable the "compile with Qt" option in cmake as this is only enabled for opencv with Qt.4.x. Just compiled like a charm.

Regards.
