Re: [Java-gnome-developer] UnsatisfiedLinkError on HTMLDocument ( html_document_new)

[Nicholas R. <ni...@mn...>]

Thanks for the info.

It is quite strange.  Here's a small test program that shows the
problem.

import java.io.IOException;
import java.net.MalformedURLException;
import org.gnu.gnome.App;
import org.gnu.gnome.Program;
import org.gnu.gtk.Gtk;
import org.gnu.gtk.ScrolledWindow;
import org.gnu.gtkhtml.HTMLDocument;
import org.gnu.gtkhtml.HTMLView;

public class TestHTML {

    public static void main( String[] argv ) {
        // Initialization
        Program.initGnomeUI("First", "0.1", argv);

        App app = new App("First", "First App");
        app.show();

        HTMLDocument document = new HTMLDocument();
        HTMLView view = new HTMLView();
        ScrolledWindow sw = new ScrolledWindow();
        sw.add( view );
        try {
            document.loadURL( "http://www.google.com" );
            view.setDocument( document );
        } catch( MalformedURLException ex ) {
            System.err.println( ex );
        } catch( IOException ex ) {
            System.err.println( ex );
        }

        Gtk.main();
    }
}

I compile and run this (with Java 1.4.2 or 1.5) and i get the following
exception:

Exception in thread "main" java.lang.UnsatisfiedLinkError:
html_document_new
        at org.gnu.gtkhtml.HTMLDocument.html_document_new(Native Method)
        at org.gnu.gtkhtml.HTMLDocument.<init>(HTMLDocument.java:44)
        at TestHTML.main(TestHTML.java:19)

I then run it with strace to see what's going on and i can see that it
is loading the correct library, but the UnsatisfiedLinkError is raised
just after the load.  However, if i run nm on my library, i can see that
the above mentioned function is in the library.

i thought then that it might be my compile of the libgtkhtml-2.6.2
library, so i re-emerged it.  didn't work.  then i compliled it by hand
into /usr/local.  still the same error.

perhaps if there's some other gentooers out there (with a standard
gentoo setup) they could try out the little program above and see what
happens.  i'll probably also post to the gentoo forum to see if anyone
there has had a similar experience.

As for a 2.8 ebuild, let me know if you want some help with testing.
Currently, I'm trying to get the CVS version of java-gnome installed,
hoping i'll have better luck with that (i have gnome 2.8 installed
already as it's in gentoo's ~x86).
