I have this error when trying to compile this:


//Libreta.java file.
import aniky.Vector;

public class Libreta {
public static void main(String[] args) {
new Vector();

}

}

--------------------------------------------------------------------
//other file Vector.class

package aniky;

public class Vector {
public Vector() {
System.out.println("euieuior");
}
}

//compiled to .class file: gcj -C Vector.java
-----------------------------------------------------------------
when: gcj --main=Libreta Libreta.java -o lib
It complains with undefined reference to Vector etc.

If only import the file no complains. If the import is from the default library no complains.

Is a very simple test, but i dont know what i am doing wrong. I have the gcj that comes with sw 12. version 4.something

AFAIK, you have to list the bytecode files explicitly for gcj if you want to produce native object code:

gcj --main=Libreta Libreta.java aniky/Vector.class -o lib

If you just want class files, there is no such restriction:

$ gcj -C Libreta.java
$ java Libreta
euieuior

That answer was just perfect. Thanks.
