Okay the fix was this:
Under Linker -> General -> Additional Library Dependencies
I put:
C:\opencv_built\lib\Debug
Pergunta
I am using this tutorial to get started with OpenCV 2.4.6 on VS 2008: http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html
I followed all instructions (my OpenCV is not in the default Program Files (x86) folder, it's in
C:\opencv_built
Unlike in the tutorial, I put very simple code, just to make sure all included files are reachable and if it builds successfully etc:
#include "stdafx.h"
#include <iostream> // for standard I/O
#include <string> // for strings
#include <iomanip> // for controlling float print precision
#include <sstream> // string to number conversion
#include <opencv2/imgproc/imgproc.hpp> // Gaussian Blur
#include <opencv2/core/core.hpp> // Basic OpenCV structures (cv::Mat, Scalar)
#include <opencv2/highgui/highgui.hpp> // OpenCV window I/O
using namespace std;
using namespace cv;
double getPSNR ( const Mat& I1, const Mat& I2);
Scalar getMSSIM( const Mat& I1, const Mat& I2);
int main(int argc, char *argv[])
{
return 0;
}
But I get a fatal error when I try to build:
fatal error C1083: Cannot open include file: 'opencv2/imgproc/imgproc.hpp': No such file or directory c:\Users\Administrator\Documents\Visual Studio 2008\Projects\firstopencv\firstopencv\firstopencv.cpp 17
This is obviously referring to this line:
#include <opencv2/imgproc/imgproc.hpp> // Gaussian Blur
I don't know where to find the dll files, or what to do next? I know this must be really easy but I've searched for any of the dll files, eg.
opencv_core243d.lib
but I get no search results.

Okay the fix was this:
Under Linker -> General -> Additional Library Dependencies
I put:
C:\opencv_built\lib\Debug
Outras dicas
1. Check your path to \vc10 folder. It should be either:
C:\opencv_built\build\x86\vc10
or
C:\opencv_built\x86\vc10
2. Go to
Start>Edit environment variables for your account>Under System variables > New...
Variable Name: OPENCV_DIR
Variable Value: Insert your path from step 1 here.
3. Open Visual Studio, make new project, go to Property Pages
4. Under C/C++ > Additional Include Directories
Insert $(OPENCV_DIR)\..\..\include
5. Under Linker > General > Additional Include Directories
Insert $(OPENCV_DIR)\lib
6a. (For DEBUG property!) Under Linker > Input > Additional Dependencies
Insert
opencv_core246d.lib
opencv_imgproc246d.lib
opencv_highgui246d.lib
opencv_ml246d.lib
opencv_video246d.lib
opencv_features2d246d.lib
opencv_calib3d246d.lib
opencv_objdetect246d.lib
opencv_contrib246d.lib
opencv_legacy246d.lib
opencv_flann246d.lib
6b. (For RELEASE property!) Under Linker > Input > Additional Dependencies
Insert
opencv_core246.lib
opencv_imgproc246.lib
opencv_highgui246.lib
opencv_ml246.lib
opencv_video246.lib
opencv_features2d246.lib
opencv_calib3d246.lib
opencv_objdetect246.lib
opencv_contrib246.lib
opencv_legacy246.lib
opencv_flann246.lib
This should be enough. If you get missing .dll window after running code, copy desired .dll from your C:\opencv_built\build\x86\vc10\bin
or C:\opencv_built\x86\vc10\bin
to your project folder.
It's not a dll file, it's a header file. The file is called imgproc.hpp
If you compiler can't find it it's either because it isn't there, or it's because you haven't told your compiler where to find it.
The important part for VS is the “Additional Include Directories”, look at that part again on the web page you followed.
