Using OpenCV 2.4.0 in a Visual studio 2010 project

Question

I have asked a similar question on How to link and use OpenCV headers?, but no luck so far. So I decided to ask a new, more specific question.

Can someone tell me wh

Answer 1

See http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to

Add these to your stdafx.h

#include <opencv2/core/core.hpp>        // cv::Mat etc, always need this
#include <opencv2/imgproc/imgproc.hpp>  // all the image processing functions
#include <opencv2/highgui/highgui.hpp>  // Display and file I/O

Assuming you have set OPENCV_DIR to the place you put opencv eg. OPENCV_DIR=c:\opencv2.4\opencv

Then set the VC++ directories in project settings to Include add $(OPENCV_DIR)\include and to Library add $(OPENCV_DIR)\lib

Then in the "linker Input" add opencv_core240.lib (opencv_core240D.lib for debug) opencv_imgproc240.lib and opencv_highgui240.lib etc

Answer 2

The folder structure of OpenCV has changed in 2.4, therefore you should use other folder than mentioned in the tutorial:

• Point OPENCV_DIR to the build-directory (e.g. C:\opencv\build), NOT the platform-specific dir.
• The Path-Variable must point to your platform-specific bin-directory (e.g. %OPENCV_DIR%\x86\vc10\bin)...
• ...same for the Linker properties (e.g. $(OPENCV_DIR)\x86\vc10\lib)
