Re: [Java-gnome-developer] Java gtk does not work anymore after gentoo update

[Abcdefg <ab...@so...>]

Thanks for your help, but it doesn't work yet, I changed my Makefile to
this:

JAVAC=gcj -C
JAVA=gij
GCJ=gcj

INCLUDES=/usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
LIBS=-lgtkjava2.6 -lgladejava2.8
LIBPATH=/usr/lib
FILES=Example.java
MAIN=Example
TARGET=Example

all:
${JAVAC} -classpath ${INCLUDES} ${FILES}

run:
${JAVA} -Djava.library.path=${LIBPATH} -classpath .:${INCLUDES} ${MAIN}

native:
${GCJ} -classpath ${INCLUDES} ${LIBS} --main=${MAIN} -o ${TARGET} ${FILES}

clean:
rm -f *.class

But I still have the same errors as described in the last mail

Also note that the error happens both with gcj and the Makefile and the
'normal' java (blackdown) because when I type
javac Example.java
and than
java -classpath
".:/usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
This is the error:
Exception in thread "main" java.lang.NoSuchMethodError:
org.gnu.gtk.Widget.makeWidget(I)Lorg/gnu/gtk/Widget;
at org.gnu.glade.LibGlade.getWidget(LibGlade.java:202)

at Example.main(Example.java:11)

could the problem be that I have libglade-java version 2.8 and gtk+-2.6? I
haven't found an ebuild for the 2.10 version

Thanks,
David

Ok, I changed the Makefile, it recognises the jar files now but gives
another error:

Do you have an idee what that means?

you are missing the l (link) - should be -lgtkjava-2.6.

Andrew, in the context of Java-Gnome there's really nothing the Sun's VM can do that GCJ/Kaffe
can't do, really. I know you know that, because you said this yourself in the email. So Sun's VM
is not a solution, because GCJ/Kaffe is not the problem here.

As for being "pro-GCJ", here goes my opinion (which is not necessarily the opinion of the JG
team):

I want the free VMs to be as good as the proprietary ones, i really do. And because i want that a
lot, i wanna help to make that happen, i don't want to just sit and wait. But how can i help?

Well, if i would contribute with code to the free VMs that would be perfect, that would be a great
contribution. But i don't think i'm that good hacker and i'm not very interested in digging into
the code of the VMs - so i take another path: i help to test and give the GCJ/Kaffe team some
feedback by actually _using_ their VMs. (Is there anything more fulfilling in free software
development than to see people actually using the software you made and giving feedback?)

Plus, by testing our code in the free VMs we garantee JG will always run in the free VMs, which is
important if you want JG to get into the distros and succeed as a viable free development
platform.

Cheers,
J.V.

Should be gtkjava-2.6, etc.  Sorry for the incorrect posting earlier.

That's because I haven't released a set of ebuilds for gtk2.6 or
lib*java 2.10 yet, so the fact you're mixing gtk 2.6 with java-gnome 2.8
stuff is at least part of your problem.

[Someone contributed a bug with a libgtk-java 2.6 ebuild. I eyeballed
it, but I haven't tested yet. Is that what you're using? The fact you're
having problems with it isn't a great sign, but I suspect your real
issue is API mixing, as mentioned]

The known-good Gentoo ebuilds are listed here:
http://www.operationaldynamics.com/reference/software/gentoo/#java-gnome
Give it a few days, and I'll have new ebuilds for java-gnome 2.10 in
there.

I started work on new debian packages last night -- libgtk-java 2.6.0 seems to
work fine with libgnome-java 2.8.3.1, etc.
