Question

我在Windows 7下编写Eclipse编程，并且在使用OpenCV库编译小程序时遇到问题（2.4.9）以下是GCC ++编译器中的路径列表，包括：＆＃34; C：\ OpenCv2.4.9 \的OpenCV \建立\包括＆＃34; ＆＃34; C：\ OpenCv2.4.9 \的OpenCV \建立\包括\ OpenCV的＆＃34; ＆＃34; C：\ OpenCv2.4.9 \的OpenCV \建立\包括\ opencv2＆＃34;

我还添加了这些库：

opencv_core249d
opencv_imgproc249d
opencv_highgui249d
opencv_ml249d
opencv_features2d249d
opencv_calib3d249d
opencv_objdetect249d
opencv_contrib249d
opencv_legacy249d
opencv_flann249d

并指出以下库搜索路径：＆＃34; C：\ OpenCv2.4.9 \的OpenCV \建立\ 86 \ VC10 \ lib中＆＃34; ＆＃34; C：\ OpenCv2.4.9 \的OpenCV \建立\ 64 \ VC10 \ lib中＆＃34;

而我不明白的是，这个程序正在编译

#include <cv.h>
#include <highgui.h>
#include <iostream>

using namespace std;
using namespace cv ;
int main ( int argc, char **argv )
{
   cvNamedWindow( "My Window", 1 );
   IplImage *img = cvCreateImage( cvSize( 640, 480 ), IPL_DEPTH_8U, 1 );
   CvFont font;
   double hScale = 1.0;
   double vScale = 1.0;
   int lineWidth = 1;
   cvInitFont( &font, CV_FONT_HERSHEY_SIMPLEX | CV_FONT_ITALIC,
          hScale, vScale, 0, lineWidth );
   cvPutText( img, "Hello World!", cvPoint( 200, 400 ), &font,
         cvScalar( 255, 255, 0 ) );
   cvShowImage( "My Window", img );
   cvWaitKey();
   return 0;
 }

即使我没有得到它的输出，以及以下程序：

#include <cv.h>
#include <highgui.h >
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"

using namespace cv;
using namespace std;

int main( int argc, char** argv )
{
  Mat image;
  image = imread( argv[1], 1 );

  if( argc != 2 || !image.data )
    {
      printf( "No image data \n" );
      return -1;
    }

  namedWindow( "Display Image", CV_WINDOW_AUTOSIZE );
  imshow( "Display Image", image );

  waitKey(0);

  return 0;
}

不编译，用红色加下代码中的opencv函数并显示这些消息：

D:\SVN\C++ Workspace\OpenCVTest\Debug/../src/main.cpp:25: undefined reference to `cv::imread(std::string const&, int)'
D:\SVN\C++ Workspace\OpenCVTest\Debug/../src/main.cpp:33: undefined reference to `cv::namedWindow(std::string const&, int)'

C:/OpenCv2.4.9/opencv/build/include/opencv2/core/mat.hpp:298: undefined reference to `cv::Mat::copySize(cv::Mat const&)'

有人可以帮我解决这个问题吗？感谢
