Java-GTK on Windows (was: Re: [Java-gnome-developer] GConf assertion failures)

since nobody answered this earlier question let me ask it again in more
general terms: what kind of difficulties should we expect when trying to
develop an application with java-gnome (most importantly -gtk) that runs
out-of-the-box on Windows?  How much experience is there with Windows as
a target platform?

GConf-support we could actually live without but easy installation on
Windows is pretty close to a must-have...

So we just talked this over in #java-gnome, and I have a hypothesis for
you.

-lglibjava is the library that we generate when you compile to native in
using GCJ that is effectively the equivalent of glib.jar. In the Gentoo
ebuilds, it only gets built if you have USE=3Dgcj set in your USE flags
(either /etc/make.conf, /etc/portage/packages.use or on emerge command
line)

So, my speculation is that you're not finding /usr/lib/libglibjava.so
because the glib-java package was built USE=3D-gcj (either explicitly by
you, or as a default by not setting the gcj use flag).

If that is so, then when you are trying to build cairo-java from CVS,
you have configured as --with-gcj-compile which is the default. As a
workaround, you can probably do

         $ ./configure --without-gcj-compile --prefix=3D/opt/blah...

Then it won't try and build the gcj native libraries libcairojava.so
that is the equivalents of cairo.jar, which means you won't need
libglibjava.so. Give it a try and let us know?

[Or, you could re emerge glib-java with USE=3Dgcj active - all assuming
that this hypothesis is correct]

Be aware that in general, if you're building something from CVS, you end
up needing to build the dependencies from CVS. That is (probably) not
necessary in this case, but there are one or two few bug fixes in
glib-java since we released 0.2.1. FYI.

I don't know much about the gentoo ebuilds myself, and from the error
snippet, it's not apparent what's going wrong. The problem is occurring
in the native compilation step, however, so you can skip that step while
we're trying to figure out why the problem is happening if you so wish.
This can be done by passing --without-gcj-compile to autogen.sh or
configure.

To help us figure out why the problem is happening, it would be useful
if you could post the whole output instead of just that small fragment.

Oh, that's awesome! I had thought about doing exactly that a while back, but the Cairo bindings
were too in-the-beginning, so i didn't go further. But this is really great.

Thanks for the quick response.  I'd like to try your patch, but so far I 
have not succeeded in building cairo-java from CVS.  I get this error 
when I execute 'make':

make[1]: *** [libcairojava.la] Error 1
make[1]: Leaving directory `/home/dgilbert/cairo-java-cvs/cairo-java'

I know nothing about this stuff, I only got cairo-java working via the 
Gentoo ebuild.  Any hints?

P.S.  By the way, my interest in cairo-java is to create a 
CairoGraphics2D class that can be used with JFreeChart (and any other 
applications that use the Graphics2D API).  I started that and got some

Hi,

It seems like a bug in the library. It would be useful if you could post
a bug report[1], so that this doesn't get lost. Regarding relevant
information to put in the bug report, the ideal is a runnable test case.
This is obviously not always possible, and the information you provided
in your email message is generally good enough, but you may probably
want to attach the file generated by the Sun JVM when it crashes. It's
usually in the directory where the app was launched from or the home
directory. Thanks.

[Java-gnome-developer] cairo-java / getMatrix() problem

[David G. <dav...@ob...>]

Hi,

I'm going a little outside my comfort zone and trying out cairo-java.  So far, it is 
going pretty well, and I've got some nice things working. But, I'm having some 
trouble when I try out transformations, specifically the following code:

         ImageSurface surface = new ImageSurface(Format.ARGB32, 300, 200);
         Context context = new Context(surface);
         Matrix m = context.getMatrix();

...generates this error message:

#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0xab1b9a73, pid=10577, tid=16384
#
# Java VM: Java HotSpot(TM) Client VM (1.4.2_09-b05 mixed mode)
# Problematic frame:
# C  [libcairo.so.2+0xca73]

I'm running Eclipse on JDK 1.4.2_09 on Gentoo Linux, and I installed the 
cairo-java-1.0.1.ebuild.

I can provide additional information if required.  I have no experience using 
"native" libraries, so I don't know what's relevant information and what's not.  Any 
help will be greatly appreciated.

Regards,

Dave Gilbert

Are there Debian or Ubuntu packages of more recent versions available
somewhere?  Or is a source-install the best option for me to get up to
date?

Sorry, I somehow expected the problem to be known.

The following simple program prints the mentioned assertion failure and
shows the returned value as beeing 0:

--->8---
package test;

import org.gnu.gconf.*;

public class Test {

	public static void main(String[] args) {
		ConfClient conf_client = ConfClient.getInstance();
		int value = -1;
		
		try {
			conf_client.setInt("/apps/test/value", 42);
			value = conf_client.getInt("/apps/test/value");
		} catch (Exception e) {
			e.printStackTrace();
		}		
		
		System.out.println(value);
	}
}
---8<---

When I change the above code to use {get,set}String everything works as
expected.

Yes, maybe.  Perhaps as soon as we got anywhere with the program we are
about to develop :)

At the moment, all that I'm prepared to offer is my gratitude for the
fact that people are working on Java bindings for Gtk, glade, etc. as
this releases us from the burdon of using such awkward toolkits as AWT,
Swing or SWT!  Hope you find the energy to keep this going!

Regards,
Lars

PS: speaking of GConf, does there exist any experience with using
GConf-Java under Windows?  Is it known or at least expected to work or
should I expect there to be major problems and therefore maybe switch to
use something else?

I don't know of anyone still using 2.10; on the other hand while there
were significant changes to libgtk-java in the last cycle, gconf isn't
getting much love.

As ever, if someone can run your test case it makes it easier for a

Forgot to mention the worst part: the call to getInt() always returns 0

[Java-gnome-developer] GConf assertion failures

[Lars W. <la...@di...>]

Hi everyone,

whenever I try to get an int value from a ConfClient using getInt I get
an assertion failure like this:

        (java-gnome:10739): GConf-CRITICAL **: gconf_client_get_int:
        assertion `err == NULL || *err == NULL' failed
        
The same is true for bool and list values.

Is this a known error in the version of Java-GConf I use (2.10.1-1 from
Ubuntu Breezy) and if so, is it going to be fixed soon (if it hasn't
been already)?  Or should I try to look more closely for an error on my
part (which seems rather unlikely to me currently)?

Regards,
Lars

[Java-gnome-developer] GNU Classpath hacker room at FOSDEM 2006

[Mark W. <ma...@kl...>]

Hi all,

Like the last couple of years we want to come together with all the
projects around GNU Classpath and the various free runtimes, compiler
and tool projects to discuss what has happened in the last year in the
Free Software community and what the next year will bring us during
FOSDEM.

The 6th edition of FOSDEM (Free and Opensource Software Developers'
European Meeting) will take place on February 25+26 2006 in Brussels
(Belgium), at the Solbosch Campus of the ULB (Free University of
Brussels). FOSDEM is a free and non-commercial event for the community
and organized by the community. See http://www.fosdem.org/

We were thinking of the following setup:

- Saturday from 13:00 to 17:30 - "End-User talks" presentations to
promote what we all build together to a wider audience that might have
heard of what we do, but haven't actually seen it in action/put
together. We might also want to have a "lightning" hour with lots of
quick Demos of applications running on a completely free stack (5 - 10
minutes per demo).

- Sunday from 09:00 to 12:30 - "Developer talks" presentations of things
that are in progress and that people want to explain in more depth to
get developers of the other projects to join in a share the fun.

- Sunday from 13:00 to 17:30 - "The Future" hard core interactive
technical hacker discussions on how to integrate the projects more and
move forward in the next year.

Arnaud Vandyck, Dalibor Topic, Mark Wielaard, Michael Koch and and Tom
Tromey will be our "program committee" this year. If you would like to
present something, have an idea for a demo or discussion topic please
let us know at fo...@de... Please mention the
title, a little abstract, which track and whether you want to do a quick
demo, a short 30 min talk or full hour talk (we prefer 30 minute talks
to give everybody a chance to present something). Deadline for proposals
is December 18, so you have a month to think of something cool. Then we
make sure to have some kind of "formal program" at the start of January.

Examples of presentations and reports from previous years:
http://www.gnu.org/software/classpath/events/escape_fosdem05.html
http://www.gnu.org/software/classpath/events/fosdem04.html

Some ideas for interesting topics:
- Free Swing - The Demo!
- Your GNU/Linux distro and the free runtimes - package overview.
- From 0 to 100 in 15 Minutes: Getting started with GNU Classpath=20
  development using Eclipse, JamVM, Mauve, and the ChangeLog plugin!
- Integrating with Objectweb through native-(gcj)-JOnAS
- Writing OpenOffice.org plugins using a free software stack.
- Using GNU Classpath/gcj/kaffe for games
- Using free runtimes on Wine and other win32 environments
- Embedding GNU Classpath in web browsers and support for JNLP
  - Security Auditing!
- 1.5 language support in GNU Classpath, gcjx and the free runtimes
- GNU Classpath/OSGi/J2ME/Library splitting and trimming
- Harmony through interfacing.
- Beyond JAPI: what is needed to "really finish" GNU Classpath
  Or, "Beyond Java" -- what we can do when we finish 1.5.
  Or more generally some kind of presentation about development
  metrics: bug rates, rates of change in japi/lines of code/tests,
  email volume, stuff like that.
- Debugging, JDWP development efforts.
- etc.

Hope to see you in Brussels on February 25 and 26 2006,

Arnaud, Dalibor, Mark, Michael and Tom

Re: [Java-gnome-developer] multiple windows

[Joao V. <jvi...@ya...>]

That's called an "MDI interface". 

Usability studies shows MDI most of the times is bad interface, and, because of that, Gtk doesn't
provide an MDI component (consequently, there isn't one in Java-Gnome).

There are 2 solutions: using tabs (doesn't feel 'right' in every situation though) or simply using
separate windows - like Gimp does (and is heavily critisized for doing it - lol :D).

Cheers,
J.V.

Re: [Java-gnome-developer] Help me compile a Glade based app natively with GCJ

[Spyros S. <fou...@gm...>]

Hi Anthony,

you were right, I should have used the full path org.test.Main. I should
have thought that it was going to be a stupid mistake.

Thank you (and everybody) for your kind help

... along with forgetting to put the class in a subdirectory matching
its package declaration (Spyros, if you want to keep the package
statement, then Main.java has to be in ./org/test assuming . is on your
classpath)

Perhaps add . to the classpath (ie. -classpath <blah>:.)?

Use --main=org.test.Main instead of just --main=Main.  This is a common
error.

[Spyros S. <fou...@gm...>]

Hi, again

I think I've found smth here:
The Main.java class contains the package declaration

package org.test;

When removing it, it seems to compile fine. When put back the linker
produces the same error. Is there a way to keep the package declaration?

Re: [Java-gnome-developer] Help me compile a Glade based app natively with GCJ

[Spyros S. <fou...@gm...>]

Adam,

Thank you for your answer however, adding :/. to the end of classpath, so
that the command looks like:

gcj -classpath
/usr/share/java/gtk2.4.jar:/usr/share/gnome2.8.jar:/usr/share/java/glade2.8=
.jar:/.
-lgtkjar2.4 -lgnomejar2.8 -lgladejar2.8 --main=3DMain -o Main Main.java
yields the same result again.

/tmp/ccYlRfbE.o(.text+0x30): In function `main':
ccADRhVT.i: undefined reference to `Main::class$'
collect2: ld returned 1 exit status
