[Java-gnome-developer] Re: java-gtk 2 error on tests

[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)
