    OpenJDK 64-Bit Server VM warning: You have loaded library /usr/lib/libtbb.so which might have disabled stack guard. The VM will try to fix the stack guard now.
    It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

i installed OpenCV with this tutorial:
https://udallascs.wordpress.com/2014/03/30/adding-opencv-and-configuring-to-work-with-eclipse-and-java/

and here is the source code:


<!-- begin snippet -->

    import com.googlecode.javacv.cpp.opencv_core.IplImage;

    //import static com.googlecode.javacv.cpp.opencv_core.*; 
    //import static com.googlecode.javacv.cpp.opencv_imgproc.*; 
    //import static com.googlecode.javacv.cpp.opencv_highgui.*;

    import java.awt.image.BufferedImage;
    import java.io.File;

    import javax.imageio.ImageIO;


    public class Main {
    	
    public static void main(String s[]) {
    	try {
    	BufferedImage bi = ImageIO.read(new File("/home/arjan/Desktop/HelloWorld.jpg"));
    	IplImage img = IplImage.createFrom(bi);
    	// cvShowImage("Hello-World",img);
    	// cvSmooth(img, img, CV_GAUSSIAN, 13);
    	// cvShowImage("Blur-Image",img); 
    	// cvWaitKey();
    	// cvReleaseImage(img); 
    	
    	}catch (Exception ex) {ex.printStackTrace();}
    }
}

I'm using arch linux and also installed OpenCV with pacman
here is a image of the jars I use [picture of jar files][1]
