Setup QT 5.5.1 + OpenCV 3.0 + Visual Studio 2013 on windows 10

1. Install Visual studio 2013 community version which is free to use for personal usage.

2. Setup the debugger follow the instruction in http://doc.qt.io/qtcreator/creator-debugger-engines.html . On windows can go to link

https://msdn.microsoft.com/en-us/library/windows/hardware/ff551063(v=vs.85).aspx to download and install Debugging Tools for Windows.

3. Install OpenCV 3.0

4. Use CMake create OpenCv 2013 solutions.

5. Build OpenCv project, target platform choose x86. ( OpenCv 3.00 cannot build success if target x64 platform)

6. Install QT. Download qt-opensource-windows-x86-msvc2013-5.5.1.exe and install. (Can not use qt-opensource-windows-x86-msvc2013_64-5.5.0.exe, because no 64 bit dynamic library available)

7. Create a QTConsole project in QT creator. Add the below blue code to the QTConsole.pro file. (Please change the include path and library path to the real path on your PC)

QT += core

QT -= gui

TARGET = QTConsole

CONFIG += console

CONFIG -= app_bundle

TEMPLATE = app

INCLUDEPATH += C:/Users/shenxiao/Downloads/opencv/build/include

LIBS += -LC:/Tools/OpenCV_MyBuild/lib/Debug 

    opencv_core300d.lib 

    opencv_highgui300d.lib 

    opencv_imgproc300d.lib 

    opencv_features2d300d.lib 

    opencv_calib3d300d.lib 

    opencv_videoio300d.lib 

    opencv_video300d.lib 

    opencv_imgcodecs300d.lib

SOURCES += main.cpp

8. Change the main.cpp to code as below.

#include <QCoreApplication>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv/cv.h"


void Test()
{
    cv::Mat mat;
    mat = cv::imread("C:\Test\QTConsole\img.jpg");
    if ( mat.empty() )
        return;
    cvNamedWindow("hello");
    cv::imshow("hello",mat);

    cvWaitKey(0);

    cv::destroyWindow("hello");
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    Test();
    printf("hello world");
    getchar();
    return a.exec();
}

9. Run QMake, build and then press F5 to run with debug.

    If the application can not start, then need to copy all the opencv build .dll files to the debug folder, together with the exe file.
