When I'm trying convert OpenCV4.1 program to wasm following error is comming

Question

When I'm trying to convert OpenCV4.1 program to wasm with the following command an error occured:

sudo /home/xxx/Documents/emsdk/upstream/emscripten/em++ -std=c++11 -s WASM=1 -I ../../../../usr/local/include/opencv4/ test.cpp  -o test.html

The following error is coming:

Simple test code:

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

using namespace cv;
using namespace std;

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

 Mat image = imread("./1.png");

 // Check for failure
 if (image.empty())
 {
  cout << "Could not open or find the image" << endl;
  cin.get();
  return -1;
 }

 String windowName = "test";

 namedWindow(windowName);

 imshow(windowName, image);

 waitKey(0);

 destroyWindow(windowName);

 return 0;
}

Please help me if anyone has any ideas.
