Sigar UnsatisfiedLinkError

Question

I'm new to Sigar. I would like to run a simple test to know how I can monitor my system.

I added sigar-1.6.4 and log4j as external libraries, but when I go to run it, I face this error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.hyperic.sigar.Sigar.getCpuInfoList()[Lorg/hyperic/sigar/CpuInfo; at org.hyperic.sigar.Sigar.getCpuInfoList(Native Method)

Here is my code:

import java.util.Map;
import org.hyperic.sigar.CpuInfo;
import org.hyperic.sigar.FileSystem;
import org.hyperic.sigar.Sigar;
import org.hyperic.sigar.SigarException;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        Sigar sigar = new Sigar();
        CpuInfo[] cpuinfo = null;
        try {
        cpuinfo = sigar.getCpuInfoList();
        } catch (SigarException se) {
        se.printStackTrace();
        }

        System.out.println("---------------------");
        System.out.println("Sigar found " + cpuinfo.length + " CPU(s)!");
        System.out.println("---------------------");
    }

}

Any help would be appreciated.

Answer 1

I understood the problem!
I have to use the following JVM Argument:

-Djava.library.path="./lib" 

in Run Configuration, Arguments tab, VM arguments in eclipse, while the contnet of sigar-bin/lib is in lib folder.
