How to concretely fix the following error message: what(): basic_string::_S_construct null not valid

dncg

Hello,

Each time I try to run this code, the unix terminal shows me the following error message:

  *  terminate called after throwing an instance of 'std::logic_error'
    what():basic_string::_ S_construct null not valid
    Press <RETURN> to close this window...*

This is my code:

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

using namespace std;
using namespace cv;

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

 //Create a window
 namedWindow( argv[1], WINDOW_AUTOSIZE );
 
 //Load an image
 Mat image=imread( argv[1] );

 //Show the image in the window
 imshow( argv[1] );

 //Clean up
 destroyWindow( argv[1] );
 exit( 0 );

}

Could you tell me how to concretely fix this problem please?
Thank you in advance

Hi and welcome to devnet,

Unless I'm missing something, this is not related to Qt. You should ask this question on the OpenCV forums
