Reading an image exits with error code -1073741515 (“Some dll not found”)

[farazk86]

I have a very simple program to test my opencv installation:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include "opencv/cv.h"
int main() {
        // read an image
        cv::Mat image= cv::imread("c:\\img.jpg");
        // create image window named "My Image"
        cv::namedWindow("My Image");
        // show the image on window
        cv::imshow("My Image", image);
        // wait key for 5000 ms
        cv::waitKey(0);
        return 1;
}

I am using Qt Creator for this and when I run the code it exits with the error: -1073741515, which according to this post:http://www.qtcentre.org/threads/57083-1073741515-problem relates to a dll not found.

This is really annoying as I am sure I have pretty much done everything according to the book. Here is my pro file:

QT       += core

QT       -= gui

TARGET = opencv_pls
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app


SOURCES += main.cpp

    -lopencv_imgproc2410.dll \
    -lopencv_features2d2410.dll \
    -lopencv_calib3d2410.dll

And here is my PATH:

Everything seems to be in order.

Dependency Walker shows these errors:

But according to this post: http://stackoverflow.com/questions/17023419/win-7-64-bit-dll-problems these are all false positives.

WHAT am I missing??? I'm nearly at the stage of pulling my hair out.
Help please

At least libstdc++-6.dll is required. Respectively all MinGW related dlls are required.

Also there are the plugins which have to be present. I think I had a similar message when the image format dlls were missing.
Did you checkout the windows deployment docs?

Hi and welcome to devnet,

To add to @koahnig , your application is probably not finding the OpenCV dlls. You would need to update the PATH variable in the Run part of the Project panel.
