我正在尝试在 OS X 10.8 中使用 Eclipse 构建以下示例：
//============================================================================
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
if( argc != 2)
{
cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
return -1;
}
Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR); // Read the file
if(! image.data ) // Check for invalid input
{
cout << "Could not open or find the image" << std::endl ;
return -1;
}
namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image ); // Show our image inside it.
waitKey(0); // Wait for a keystroke in the window
return 0;
}
但得到这个结果：

我已经安装了 opencv，以便 pkg-config 报告以下内容：
$ pkg-config opencv --cflags
-I/opt/local/include/opencv -I/opt/local/include
和
$ pkg-config --libs opencv
/opt/local/lib/libopencv_calib3d.dylib /opt/local/lib/libopencv_contrib.dylib /opt/local/lib/libopencv_core.dylib /opt/local/lib/libopencv_features2d.dylib /opt/local/lib/libopencv_flann.dylib /opt/local/lib/libopencv_gpu.dylib /opt/local/lib/libopencv_highgui.dylib /opt/local/lib/libopencv_imgproc.dylib /opt/local/lib/libopencv_legacy.dylib /opt/local/lib/libopencv_ml.dylib /opt/local/lib/libopencv_nonfree.dylib /opt/local/lib/libopencv_objdetect.dylib /opt/local/lib/libopencv_photo.dylib /opt/local/lib/libopencv_stitching.dylib /opt/local/lib/libopencv_ts.dylib /opt/local/lib/libopencv_video.dylib /opt/local/lib/libopencv_videostab.dylib
在 Eclipse 中，在我拥有的项目属性中，C/C++ Build -> Settings -> GCC C++ Compiler "All options" 设置为：
-I/opt/local/include/opencv -I/opt/local/include/opencv2 -O0 -g3 -Wall -c -fmessage-length=0
并且 C/C++ Build -> Settings -> MacOS X C++ Linker -> "All options" 设置为：-L/opt/local/lib
我还在 C/C++ Build -> Settings -> MacOS X C++ Linker -> Libraries 中列出了以下库 (-l)：
opencv_core opencv_imgproc opencv_highgui opencv_ml opencv_video opencv_features2d opencv_calib3d opencv_objdetect opencv_contrib opencv_legacy opencv_flann
我可以在 Ubuntu 中构建相同的示例，而不是在 OS X 中。任何人都可以帮助解释 Eclipse 在 OS X 中使用的路径的设置，用于 opencv 吗？
