LINK : fatal error LNK1104: cannot open file 'opencv_core242d.lib'

edit

Hello. I got similar problem. I read book, tutorials etc and it still don't work. Now I have download latest version of OpenCV (2.4.3). Include to my project ( in include directories) "D:\opencv\build\include\opencv2", "D:\opencv\build\include","D:\opencv\build\include\opencv" and in library directories library path "D:\opencv\build\x86\vc10\lib". And in Linker/Input/Additional Dependencies i add opencv_core243d.lib opencv_imgproc243d.lib opencv_highgui243d.lib opencv_ml243d.lib opencv_video243d.lib opencv_features2d243d.lib opencv_calib3d243d.lib opencv_objdetect243d.lib opencv_contrib243d.lib opencv_legacy243d.lib opencv_flann243d.lib

Now i can compile it. But after i run i got error Canot run this application because can't find opencv_core243d.dll. Reinstall should help.

Yeah "Crash"'s answer is right...But this error also occurs to me when I change my OpenCV version from 2.4.6 to 2.4.9 . I did'nt notice that my .lib files was change from opencv_core246d.lib to opencv_core249d.lib, and so on and so forth. You must also consider this thing.

I think I fixed the problem(first example of code is working). I install opencv on ubuntu ( sudo apt-get install libopencv-dev or something like that in ubuntu terminal ). Then you must create new project in QT Creator (file>new project> qt console application). You will get 2 files main.cpp and your_project_name.proj. Type in 'your_project_name.proj' "INCLUDEPATH += I/usr/include/" "LIBS += -lopencv_core \ -lopencv_highgui \ -lopencv_imgproc \ -lopencv_features2d \ -lopencv_calib3d"

The code in main.cpp file is

#include< opencv2/core/core.hpp>

#include< opencv2/highgui/highgui.hpp>

int main()

{

cv::Mat koko = cv::imread("plik.jpg");
cv::namedWindow("Oko");
cv::imshow("oko",koko);
cv::waitKey(5000);

return 0;

}

And it's work fine. I don't check any other examples.

Hi everybody , I've the same problem but this time with world2411 , the msg error is : Error 1 error LNK1104: cannot open file 'opencv_world2411d.lib' , I've checked the configuration (libs....../ release and Debug) and all is good , but I've noticed that a file called "world" exist in the modules file but I can't find it here : C:\opencv\build\x86\vc12\lib , any suggestions plz :)

Intellisense will only predict compiler errors, this is a link stage error. You need to add the appropriate library directory to your project configuration. For a 32-bit project use opencv-2.4.x\build\x86\vc10\lib.
