Qt4 or Qt5 (mingw) and openCV 2.4.6 - qt

Question

I have problems with setting up Qt with opencv:
With Qt5 cMake unable to finish the configuration. Luckily with Qt4 it works fine. (default only Qt)
mingw32-make
mingw32-make install
(this runs without error)
But when I use InputVideo which is in highgui, it stops runtime.
Checking with dependecy walker, the LIBOPENCV_HIGHGUI246.DLL has dependecies like:
API-MS-WIN-CORE-KERNEL32-PRIVATE-L1-1-1.DLL
API-MS-WIN-CORE-PRIVATEPROFILE-L1-1-1.DLL
API-MS-WIN-SERVICE-PRIVATE-L1-1-1.DLL
...
these are in theory part of windows8. How can i fix this problem?
(besides moving all dll-s near my executable)

Answer 1

I managed to configure a Qt Creator project with OpenCV to run a simple OpenCV application I wrote recently, named cvDisplacementMapFilter.
I tested it with OpenCV 2.4.7 on Mac OS X 10.7.5 and OpenCV 2.4.2 on Windows 7. I believe the following .pro file can help you:
SOURCES += \
main.cpp
# On my system I have to specify g++ as compiler else it will use clang++ by default
QMAKE_CXX=g++
QMAKE_CC=gcc
## OpenCV settings for Unix/Linux
unix:!mac {
message("* Using settings for Unix/Linux.")
INCLUDEPATH += /usr/local/include/opencv
LIBS += -L/usr/local/lib/ \
-lopencv_core \
-lopencv_highgui \
-lopencv_imgproc
}
## OpenCV settings for Mac OS X
macx {
message("* Using settings for Mac OS X.")
INCLUDEPATH += /usr/local/include/opencv
LIBS += -L/usr/local/lib/ \
-lopencv_core \
-lopencv_highgui \
-lopencv_imgproc
}
## OpenCV settings for Windows and OpenCV 2.4.2
win32 {
message("* Using settings for Windows.")
INCLUDEPATH += "C:\\opencv\\build\\include" \
"C:\\opencv\\build\\include\\opencv" \
"C:\\opencv\\build\\include\\opencv2"
LIBS += -L"C:\\opencv\\build\\x86\\vc10\\lib" \
-lopencv_core242 \
-lopencv_highgui242 \
-lopencv_imgproc242
}
Don't forget to change the paths and version of OpenCV at win32.
