Failed to use my JNAerator built jar though added it in the classpath

I've donwloaded the latest JNAerator jar (jnaerator-0.12-SNAPSHOT-20130609) here. Then, from my Ubuntu 13.04 64 bits, I translated a simple C source (just below) with the command :

java -jar jnaerator-0.12-SNAPSHOT-20130609.jar -gui -mode StandaloneJar operations.c

so that I get a jar operations.jar

---

operations.c :

int myAddtion(int a, int b){
    return a+b;
}

---

Then I add this jar to my Eclipse (Juno 4.1) test project build path : here the screenshot of my project organisation

and here is the single source file of my project :

package com.gmail.loloof64.j2se.bon_compte.operations;

import operations.OperationsLibrary;

public class BonCompteTest {

    public static void main(String[] args) {
        System.out.println(OperationsLibrary.myAddtion(10, 30));
    }
}

But I get the following error output :

juil. 02, 2013 1:19:47 PM org.bridj.BridJ log
INFO: Library not found : operations
juil. 02, 2013 1:19:47 PM org.bridj.BridJ log

# BridJ: dlopen error when loading operations : operations: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou dossier de ce type
# BridJ: dlopen error when loading operations : operations: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou dossier de ce type

(The last sentence means : Can't open shared object file : No file or folder of this type).

I am using sun Java7 JDK (64 bits).

Does someone knows what I forgot ?

I am sure that there must be a problem like the fact that my C source file is missing, but I have tried to add it to the project, and to the jar, at several locations, but it did not solved my problem.

These logs (and your command line) seem to indicate that BridJ failed to find your native library (i.e. the .dll / .so / .dylib file). To fix that, you have a few options:

• Provide your library as a command-line argument to JNAerator
• If the library is installed on your system, adjust the platform-specific lookup paths: see Libraries Lookup on the wiki
• Point at its full path during runtime using the environment variable BRIDJ_OPERATIONS_LIBRARY=path or the java property -Dbridj.operations.library=path
