Qt OpenCV程序退出，代码为-1073741515

Question

What i want to do

I try to use opencv and run a short example program.

Problem

It exits with code -1073741515 . I never managed to use openCV on any of the 4 systems i tried, so i do something wrong but don't know what.

I had diffrenet errors using different attempts (undefined reference, crashing programm without error code, etc.), this here is the just simplest example.

What i figured out

Another post told me, that -1073741515 is equal to 0xC0000135 meaning STATUS_DLL_NOT_FOUND .

What i tried

The programm crashes, if include #include <opencv2/core/core.hpp> , #include <opencv2/highgui/highgui.hpp> and #include <opencv2/imgproc/imgproc.hpp> . When i comment them out, it runs wnd returns 0 as intended. I don't even need to use anything like cv::Mat or something to make it crash. That seems strange, because the code completion suggests me stuff from openCV, so it somehow sees it. Including #include <opencv2/opencv.hpp> instead leads to the same error code. Including something beginning with opencv (not opencv2) works, for example #include <opencv/cv.hpp> , but has not enough functionality.

Source file

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

#include <iostream>
using namespace std;

int main()
{
    cv::Mat InputImage = cv::imread("C:/Users/Public/Pictures/Sample Pictures/Chrysanthemum.jpg");

    if(!InputImage.empty())
        cv::imshow("test", InputImage);
    else
        cout << "imgage is empty" << endl;

    return 0;
}

Answer 1

As Jiu pointed out in the comment above, the solution was simple:

Copy the .dll not the .lib and it works.
