JavaCV startet nicht

Question

Die erste Sache: Ich bin kein englischer Muttersprachler, also versuche ich mein Bestes zu geben. Ich versuche, JavaCV zu verwenden, aber es funktioniert nicht. Ich erhalte den Fehler:

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 OpenCV mit diesem Tutorial installiert: https://udallascs.wordpress.com/2014/03/30/adding-opencv-and-configuring-to-work-with-eclipse-and-java/

und hier wird der Quellcode:

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();} 
} 

}

Ich Arch Linux verwenden und auch installiert OpenCV mit Pacman hier ist ein Bild der Gläser I picture of jar files

Folgen Sie @ m-prokhorov verwenden. Die von Ihnen gepostete Fehlermeldung sagt deutlich:

Caused by: java.lang.UnsatisfiedLinkError: no jniopencv_core in java.library.path.

Jetzt können Sie diesen Ausdruck in einer Internet-Suchmaschine, der Sie vertrauen, oder sogar SO selbst suchen: Getting JavaCV 0.9 platform binaries to download automatically with SBT.
