     Recently I decided to update my OpenCV from 2.4 up to 3.2. I went through problems, and errors since am coding with C++ in Eclipse and using MinGW on Windows 10. After a little struggle, I finally got it running. Here is the step by step I used.

UPDATE: The latest version of OpenCV is now 3.3, to stay up-to-date please access the newer version of this article here. If for some reason you still want the 3.2 guide, ignore this note and continue.



 

Getting started

– You will need:

 

Configuring OpenCV

  • Add MinGW to System Path
    – Search for Environment variables;
    – Click on Path, and Edit;
    – Then, New, and add the address of your MinGW bin folder.

Adding environment variables

 

  • Extract OpenCV to a folder, rename it
    opencv_src
    – Inside it, create a folder named
    Mingw_build

 

Now, let’s compile OpenCV

  • Open CMake-gui;
  • set src folder as
    opencv_src
    and build folder as
    opencv_src/Mingw_build/

Setting build and source folder for OpenCV

 

  • Click on Configure, choosing
    Eclipse CDT4 - MinGW MakeFile
    in the next window, then next;
  • Wait for the entire configuration, then hit generate;
  • Now, open the CMD, and navigate to
    opencv_src/Mingw_build/
  • Inside
    opencv_src/Mingw_build
    type
    mingw32-make
    and hit enter;
    – This step probably will take a while, wait until it’s finished.
  • Install using
    mingw32-make install
  • Finally, add
    C:\opencv_src\Mingw_build\install\x86\mingw\bin
    to your system path.

 

Configuring Eclipse

  • Open it and create a C++ program using the following OpenCV  example:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
 
using namespace cv;
using namespace std;
 
int main( int argc, char** argv )
{
    if( argc != 2)
    {
     cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
     return -1;
    }
 
    Mat image;
    image = imread(argv[1], CV_LOAD_IMAGE_COLOR);   // Read the file
 
    if(! image.data )                              // Check for invalid input
    {
        cout <<  "Could not open or find the image" << std::endl ;
        return -1;
    }
 
    namedWindow( "Display window", WINDOW_AUTOSIZE );// Create a window for display.
    imshow( "Display window", image );                   // Show our image inside it.
 
    waitKey(0);                                          // Wait for a keystroke in the window
    return 0;
}

 

  • Go to
    Project > Properties > C/C++ Build > Settings > GCC C++ Compiler > Includes
    and add the source OpenCV folder
    C:\opencv_src\Mingw_build\install\include

Project > Properties > C/C++ Build > Settings > GCC C++ Compiler > Includes

 

  • Go to
    Project > Properties > C/C++ Build > Settings > MinGW C++ Linker > Libraries
    , and add this to the Libraries (-l), separately as shown in the image

Project > Properties > C/C++ Build > Settings > MinGW C++ Linker > Libraries

 

  • You can  add additional libraries from lib folder if you need, just follow the presented format;
  • Add
    C:\opencv_src\Mingw_build\install\x86\mingw\lib
    to Library search path (-L);
  • Build the project. It will work flawlessly;
  • The code and configuration files can be found here.

 
 

 

 

Have fun with your projects!

  1. Hi,
    My build is failing when i enter the command mingw32-make, I am unable to know the reason for the fail.
    Could you help me out?
    Steps i am done with:
    Extracted OpenCV 3.4.0
    from the Cmake GUI, I was able to configure and generate.

  5. Jean,

    Both entries are already there in the files 🙁 I was going through various forums and got to know about following changes to be made in precomp.hpp in highgui which solve the error yet set up could not complete.

    #if defined _WIN32 || defined WINCE
    #if !defined _WIN32_WINNT
    #ifdef HAVE_MSMF
    #define _WIN32_WINNT 0x0600 // Windows Vista
    #else
    #define _WIN32_WINNT 0x0500 // Windows 2000
    #endif
    #endif

    however now errors are here..

    At global scope:
    C:\opencv\sources\modules\highgui\src\window.cpp:552:37: error: ‘ButtonCallback’ has not been declared
    C:\opencv\sources\modules\highgui\src\window.cpp:552:71: error: ‘int cv::createButton(const cv::String&, int, void*, int, bool)’ should have been declared inside ‘cv’

    mingw32-make: *** [all] Error 2

  6. i am trying to run the following code to access the web cam
    #include
    #include
    #include

    using namespace std;
    using namespace cv;

    int main(int argc, const char *argv[])
    {
    VideoCapture vid(0);
    if(!vid.isOpened()){
    cout<<"Camera could not load…"<<endl;
    return -1;
    }
    namedWindow("webcam",CV_WINDOW_AUTOSIZE);
    while(1){
    Mat frame;
    bool ctrl = vid.read(frame);
    imshow("webcam",frame);
    if(waitKey(0) == 27){
    cout<<"The app is ended…"<<endl;
    break;
    }
    }
    return 0;
    }

    it failed with the following error, please help me in solving it

    Description Resource Path Location Type
    undefined reference to `cv::VideoCapture::~VideoCapture()' abcd.cpp /opencv line 10 C/C++ Problem

  7. I am using Windows 10 with eclipse oxygen.
    While building,it shows configuration debug uses tool-chain mingw-gcc that is not supported on this system,attempting to build anyway.
    Could you please suggest any alternative.

  11. Hello, can you show how to run open cv libraries in ARM based micro controllers(ARM_CORTEX-M4). I have SDK with Eclipse IDE, MinGW and python packages.
    Please help me…..
