Tutorial integrating Code::Blocks and OpenCV 2.1.0

In this tutorial, we will learn about “how to integrate Code::Blocks and OpenCV 2.1.0”. For OpenCV 2.2.0, please see my other tutorial about “Tutorial integrating Code::Blocks and OpenCV 2.2.0”.

You must have OpenCV 2.1.0 and Code::Blocks installed on your system. If you don’t have it, please see my other tutorial how to installing them in this blog.

Ok, lets jump to the tutorial step.

  1. We assume that you have installed opencv and codeblocks on your computer. So ,we jump to the next step.
  2. Run Code::Blocks and select on the menu “Setting->Compiler and debugger” like image below.
  3. Next, you will see a dialog for Compiler and debugger settings like image below, on the “search directories” tab select “compiler” tab and add opencv include directory by click “Add” button on the bottom.
  4. Next, On the “search directories” tab select “linker” tab and add opencv library directory by click “Add” button on the bottom like image below.
  5. Next, still on a dialog for Compiler and debugger settings, select “Linker setting” tab and add opencv include file by click “Add” button on the bottom like image below.
  6. Create New project from menu “File->New->Project”, select “Console Application”, choose C++ project and give project name. Select “GNU GCC Compiler” and click “Finish” button.
  7. On the left panel expand folder “src” and then open main.cpp. On the code editor put this code bellow.
    #include "stdio.h"
    #include "cv.h"
    #include "highgui.h"
    
    int main(int argc, char** argv)
    {
     IplImage *img = cvLoadImage("lena.jpg", CV_LOAD_IMAGE_COLOR);
    
     /* initialize font and add text */
     CvFont font;
     cvInitFont(&font, CV_FONT_HERSHEY_SIMPLEX, 1.0, 1.0, 0, 1, CV_AA);
     cvPutText(img, "Hello World!", cvPoint(10, 50), &font, cvScalar(255, 255, 255, 0));
    
     /* display the image */
     cvNamedWindow("image", CV_WINDOW_AUTOSIZE);
     cvShowImage("image", img);
     cvWaitKey(0);
     cvDestroyWindow("image");
     cvReleaseImage( &img );
    
     return 0;
    
    }
    
    
  8. Build and run project by press “F9”. (Note: you must put image file on the project folder first and then run project.)
  9. Then you will see result like image below. Congratulation you are successful integrate Code::Blocks and OpenCV. Have fun…
