fatal error LNK1104: cannot open file 'opencv_calib3d246.dll'

Question

I'm trying to run visual c++ with OpenCV. I have linked the OpenCV to Visual studio 2012. when I tried to run the code, it's giving me an error;

LINK : fatal error LNK1104: cannot open file 'opencv_calib2d246.dll'

Here's what I was trying to do:

#include "stdafx.h"
#include "opencv2\highgui\highgui.hpp"
#include "opencv2\core\core.hpp"
#include<iostream>

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
    if(argc !=2)
    {
        cout <<"usage: display_image ImageToLoadAndDisplay"<<endl;
        return -1;
    }

    Mat image;
    image=imread(argv[1],CV_LOAD_IMAGE_UNCHANGED);

    if(! image.data)
    {
        cout<<"couldn't open or find the image"<<endl;
        return -1;
    }

    namedWindow("Display Window",WINDOW_AUTOSIZE);
    imshow("Display Window",image);

    waitKey(0);
    return 0;
}

I have included all the libraries. I'm using OpenCV 2.4.6, on windows 7 32 bit system.

Anything more I have to add, or do I have to initialize it in the program?

Update

The path for OpenCV in my hard disk :E:\opencv\opencv. Path in the system environment variable: %OPENCV_DIR%\x86\vc11\bin;, where I have created a new variable as OPENCV_DIR and have given the path as E:\opencv\opencv\build. And in linker\command line

/OUT:"E:\VS2012 Projects\cvtest\Debug\cvtest.exe" /MANIFEST /NXCOMPAT /PDB:"E:\VS2012 Projects\cvtest\Debug\cvtest.pdb" /DYNAMICBASE "opencv_calib3d248.lib" "opencv_calib3d248d.lib" "opencv_contrib248.lib" "opencv_contrib248d.lib" "opencv_core248.lib" "opencv_core248d.lib" "opencv_features2d248.lib" "opencv_features2d248d.lib" "opencv_flann248.lib" "opencv_flann248d.lib" "opencv_gpu248.lib" "opencv_gpu248d.lib" "opencv_highgui248.lib" "opencv_highgui248d.lib" "opencv_imgproc248.lib" "opencv_imgproc248d.lib" "opencv_legacy248.lib" "opencv_legacy248d.lib" "opencv_ml248.lib" "opencv_ml248d.lib" "opencv_nonfree248.lib" "opencv_nonfree248d.lib" "opencv_objdetect248.lib" "opencv_objdetect248d.lib" "opencv_ocl248.lib" "opencv_ocl248d.lib" "opencv_photo248.lib" "opencv_photo248d.lib" "opencv_stitching248.lib" "opencv_stitching248d.lib" "opencv_superres248.lib" "opencv_superres248d.lib" "opencv_ts248.lib" "opencv_ts248d.lib" "opencv_video248.lib" "opencv_video248d.lib" "opencv_videostab248.lib" "opencv_videostab248d.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" /DEBUG /MACHINE:X86 /INCREMENTAL /PGD:"E:\VS2012 Projects\cvtest\Debug\cvtest.pgd" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /ManifestFile:"Debug\cvtest.exe.intermediate.manifest" /ERRORREPORT:PROMPT /NOLOGO /TLBID:1

Now I'm not able to load image. No fatal errors and nothing. It is considering the if statement and not loading anything.

Any suggestions?

did you add reference to this dll? i tried using opencv in c# i just added it in the reference — DarkMakukudo
go to linker/general and add the path where that .lib file is located to "additonal linker directories" or similar — Micka
@Micka I have checked the path. I have specified the path as well. Still I'm getting the same error. — varsha_holla
@EuphoriaGrogi I haven't tried it by adding the reference. I will check that out. — varsha_holla
either add : %OPENCV_DIR%\x86\vc11\lib; to system PATH environmental variable or add it to "additional library directories" in linker->general — Micka

You need to set up more than just your linker dependencies and it is very likely you have missed a step.

I would suggest following this tutorial as it will get you setup completely.
