I also think its very nice stuff! The GCJ-native compilation-feature i lik=
e best. But my makfile doesnt compile that gcj-stuff well, so...

In the source-directory there is an /lib -dir. Inthis directory there are =
some files. Copy the file libGTK.so to /usr/lib and run ldconfig as su, or=
 set the LD=5FLIBRARY=5FPATH with "export LD=5FLIBRARY=5FPATH=3D/../.." to the driec=
tory which contains such a file.

Dankt thinnk so. But its needed if you want to load xml-file made with gla=
de.

I=B4m soory, I dont know it exaclty. I=B4m also very new here...

Yeas this is a little bit tricky for not java-jni experts. I have also ver=
y much problems...
Currently I can only use Kaffe to run my java-gtk examples, because i dont=
 know the standard-classpath of the jdk1.4 (intalled in /opt/java1.4/). So=
 f I set CLASSPATH=3D/usr/lib/gtk.jar it doesnt find the java.lang and other=
 packages...
Maybe you can help me=3F

Much luck and fun with java-gtk!

[cedric <ced...@fr...>]

Hi,
I just resolved my problem. The error was in my libGTKJava.so.0.8.0 binary,
which lacks of all the symbols from the libglade-2.0. I didn't know if the
problem come from my system or the java-gnome configure.in but the solution
permits to have a working java-gtk system....GREAT!
=> I am able to run all "java TestGTK" tests (run as good as Swing...speed
is very good)
without any problems (with sun jdk1.4, GTK2 version 2.0.1, libglade and
libxml from Gnome2 pre1)
THANKS A LOT TO ALL THE WORKER. I expect to give apps for the examples
directory, as soon as I have time to do one, of course :-)

For Clemens Eisserer: your classpath problem isn't. Even with only
CLASSPATH=/usr/gnome/share/java-gnome/gtk.jar:. set on my linux box, I have
no errors like "java.lang not found".
Maybe try to set "export JAVA_HOME=/opt/java1.4" or even "export
PATH=/opt/java1.4/bin:$PATH". Good luck. May be I will have some time to try
to compile and run the TestGTK using gcj...not sure.

----------------------------------------------------------------------------
----------
SOLUTION (edit the paths to reflect your gnome2 installation path!!):
1. edit the makefile in src directory to complete this lines (which were
empty for me)
(else all must work well):
LIBGLADE_CFLAGS= -I/usr/gnome2/include/libglade-2.0 -I/usr/gnome2/include/li
bxml2/libxml
LIBGLADE_LIBS= -lglade-2.0
2. type make all (or "make gtk_nativelib" to build only the
libGTKJava.so.0.8.0)

I also can also only say thanks for this great stuff. It comines two 
very nice things: The Java-programming language, which is very intuitive 
and clean, and the fast and nice gtk native widget support.

Thanks for your tipps! That doesnt really matter. I can now compile my 
code with gcj - I found a mistake in the build-scripts so i built it my 
own....
Great!
