OpenCv Compiling With Code::Blocks on Windows

Question

I want to use the opencv library with code::blocks.

I am using windows 7 Pro x86 os. I've installed Code::Blocks 13.12.

I've download and extract opencv library on my disk (C:\Opencv242).

I also have opencv 2.4.9 and some other versions.

I already tried so much method. I never compilied succesfully. Every time it get me some errors.

Like;

for this code:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/opencv.hpp>
#include <iostream>

using namespace std;
using namespace cv;

int main()
{

Mat img = imread("C:\\PROJELER\\Software Projects\\Opencv\\pic.jpg", CV_LOAD_IMAGE_COLOR);

namedWindow("MyWindow", CV_WINDOW_AUTOSIZE);
imshow("MyWindow", img);

waitKey(0);
return 0;
}

It getting theese errors to me;

||=== Build: Debug in Opencv (compiler: GNU GCC Compiler) ===| obj\Debug\main.o||In function main':| C:\PROJELER\Software Projects\Opencv\main.cpp|12|undefined reference tocv::imread(std::string const&, int)'| C:\PROJELER\Software Projects\Opencv\main.cpp|14|undefined reference to cv::namedWindow(std::string const&, int)'| C:\PROJELER\Software Projects\Opencv\main.cpp|15|undefined reference tocv::_InputArray::_InputArray(cv::Mat const&)'| C:\PROJELER\Software Projects\Opencv\main.cpp|15|undefined reference to cv::imshow(std::string const&, cv::_InputArray const&)'| C:\PROJELER\Software Projects\Opencv\main.cpp|17|undefined reference tocv::waitKey(int)'| obj\Debug\main.o||In function ZN2cv3MatD1Ev':| C:\PROJELER\Software Projects\Opencv\..\..\..\Opencv242\opencv\build\include\opencv2\core\mat.hpp|278|undefined reference tocv::fastFree(void*)'| obj\Debug\main.o||In function ZN2cv3Mat7releaseEv':| C:\PROJELER\Software Projects\Opencv\..\..\..\Opencv242\opencv\build\include\opencv2\core\mat.hpp|367|undefined reference tocv::Mat::deallocate()'| ||=== Build failed: 7 error(s), 0 warning(s) (0 minute(s), 1 second(s)) ===|

I want to clean install.But i dont know how.

I followed so many person.Last I tried this one;

http://kevinhughes.ca/tutorials/opencv-install-on-windows-with-codeblocks-and-mingw/

Can any one help me how is this?Which way is the right one?

Thanks all of you.

I hope some one help and somehow this problem is solve.

By the way i forget some details.So sorry.. I've added system path opencv\build\x86\bin, c:\mingw\bin,cmake\bin,codeblocks and some others. — yldzmuhammed

there were a lot of problems with prebuilt mingw libs due to the fact that you have to use exactly the same mingw setup used when compiling the libs, so they ditched that lately. do yourself a favour and build them from the 2.4.9 src using cmake. — berak

honestly, the whole mingw thing involves a certain amount of masochism. — berak

You need to add linker directory path. For more info, check this link: OpenCV Codeblocks Setup
