I successfully compiled and installed the `3.1.0-dev`
#pkg-config
$pkg-config --libs --cflags opencv

#main.cpp:
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
using namespace std;
using namespace cv;
Mat src; Mat dst;
char window_name1[] = "Unprocessed Image";
char window_name2[] = "Processed Image";
int main( int argc, char** argv )
{
/// Load the source image
src = imread( argv[1], 1 );
namedWindow( window_name1, WINDOW_AUTOSIZE );
imshow("Unprocessed Image",src);
dst = src.clone();
GaussianBlur( src, dst, Size( 15, 15 ), 0, 0 );
namedWindow( window_name2, WINDOW_AUTOSIZE );
imshow("Processed Image",dst);
waitKey();
return 0;
}
I can compile and execute `main.o` by using very simple argument
g++ main.cpp `pkg-config --cflags --libs opencv` -o main.o
./main.o image.jpg
But when I put my `include` and `libs` directory to `Eclipe`
