Opencv2.4.0 with mingw in windows get crashed

问题:

I followed steps in this SO link to compile a sample program using OpenCV2.4.0 in windows. I made a setup both in DEVC++ and NetBeans with Mingw. My sample Program is getting Compiled properly, but when I run the exe the application get crashes.

But In same machine I used opencv2.1.0 and the same sample program gets compiled and there is no crash while running it.

The below is the Sample Code I tried to execute:

#include "highgui.h"
using namespace std;
int main( int argc, char** argv ) {
IplImage* img = cvLoadImage( "C:\\Documents and Settings\\All Users\\Documents\\My Pictures\\Sample Pictures\\Water lilies.jpg" );
cvNamedWindow( "Sample", CV_WINDOW_AUTOSIZE );
cvShowImage( "Sample", img );
cvWaitKey(0);
cvReleaseImage( &img );
cvDestroyWindow( "Sample" );
} 

UPDATE :

I follwed as the steps as moskito-x link to build the opencv and when I press "configure", I get the following error. And my make file is also 35kb in size. Any suggestions to solve this?

回答1:

Using the libs in "...\opencv\build\x86\mingw\bin" and "...\opencv\build\x86\mingw\lib

You can not use the libraries that come with OpenCV-2.4.x.exe.

As some developers in forums and I find out. On some systems, the precompiled libs of "opencv 2.4.x" can not be used.
To compile your own programs, works, but it crashed if you try to run them. Until there are not functioning precompiled libs of "opencv 2.4.x , you have to compile opencv yourself.

Ignore so the folder "...\opencv\build\x86\mingw\bin" and "...\opencv\build\x86\mingw\lib" completely.

As already pointed out you can't rely on precompiled binaries. I also had a lot of problems and finally ended up with compiling my own binaries. My setup was for Windows7, Eclipse CDT (Juno) and MinGW. You can check my post on Stackoverflow here

I guess this is an error related to memory management. Maybe because your'e releasing the window before the image. But anyhow you should use the OpenCV C++ interface, as this does a lot of stuff automagically. With the C++ Interface your code would look like this:

    #include <opencv.hpp>

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

            cv::Mat img = cv::imread("C:\\Documents and Settings\\All Users\\Documents\\My Pictures\\Sample Pictures\\Water lilies.jpg");

            cv::imshow("Sample", img);
            cv::waitKey(0);

            return 0
    }
