Solved - Segmentation fault (core dumped) - When running simple OpenCV compiled code

C++
7

I’m not too sure how to catch the exception using the try and catch method, never played around much of it. (yes, I am beginner c++) I’ll figure it out soon but I do know how to play around with the debugger.

I think the gtk is disabled on opencv. I do know I have gtk3-3.24.34 installed in the OS.

I have come up with this code:

#include <iostream>
#include "opencv2/highgui/highgui.hpp" 

using namespace cv; 

int main( int argc, char** argv ) 
{ 
    int e;

    try
    {
        Mat img = imread( argv[1]); 

        if( img.empty() ) {return -1;}

        namedWindow( "Example1", WINDOW_AUTOSIZE );

        imshow( "Example1", img ); 

        waitKey( 0 ); 

        destroyWindow( "Example1" );

        throw e;
    }

    catch (int e)
    {
        std::cout << "An exception occurred. Exception Nr. " << e << '\n';
    }
    return 0;
}

I do not get any exceptions, same error as to the 1st post.

Edit:

I was able to fix the problem. I needed to recompile OpenCV with GTK3 enabled since for some reason it is disabled for the FreeBSD’s distribution of OpenCV. I would like to know if anyone was able to get OpenCV 4.6.0 compiled and working on FreeBSD 13.1 since 4.6.0 is not available on the FreeBSD distribution yet.
