OS X 10.8 で Eclipse を使用して次の例をビルドしようとしています。
//============================================================================
#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;
}
しかし、この結果が得られます:

pkg-config が次のように報告するように opencv をインストールしました。
$ pkg-config opencv --cflags
-I/opt/local/include/opencv -I/opt/local/include
と
$ pkg-config --libs opencv

そしてEclipse内で、私が持っているプロジェクトのプロパティで、C/C++ Build -> Settings -> GCC C++ Compiler "All options" set to:
-I/opt/local/include/opencv -I/opt/local/include/opencv2 -O0 -g3 -Wall -c -fmessage-length=0
C/C++ Build -> Settings -> MacOS X C++ Linker -> "All options" は次のように設定されています: -L/opt/local/lib
C/C++ Build -> Settings -> MacOS X C++ Linker -> Libraries に次のライブラリ (-l) もリストされています。
opencv_core opencv_imgproc opencv_highgui opencv_ml opencv_video opencv_features2d opencv_calib3d opencv_objdetect opencv_contrib opencv_legacy opencv_flann
OS Xではなく、Ubuntuでこの同じ例を構築できます。opencvのOS XでEclipseが使用するパスのセットアップを説明できる人はいますか?
