GCJ and AWT

[Antonio Fiol Bonnín <fiol.bonnin@terra.es>]

Hello,

I am new to GCJ, but not to Java or Debian.

I have a fairly simple application I would like to compile using GCJ in 
order to get a native binary. I have succeeded to get my binary, but it 
does not work.

As of February 2002, I read on this list archives that AWT was not 
usable. However, it seems that since then things may have changed.

What I get is:
Exception in thread "main": java.awt.AWTError: Cannot load AWT toolkit: 
gnu.java.awt.peer.gtk.GtkToolkit

being the fourth (and AFAICT important) line of the stack trace:
at ...: java.awt.Toolkit.getDefaultToolkit() ...

I compiled it with:

gcj-3.2 --main=MyMainClass -o MyMainClass *.java


If I try the jikes-compiled version of it, packaged in a jar, like:
gij-3.2 -jar myjar.jar

I get exactly the same error.

I have tried to install the classpath package, and to export 
LD_LIBRARY_PATH=/usr/lib/classpath before I try to run my app, but it 
does not seem to help at all.

If I ldd MyMainClass, I do not get any broken library reference.

I saw that there are some unavailable classes, such as GridBagLayout, 
but I rewrote the code to avoid this little hassle. So now it compiles 
OK, but it does not run.

BTW, before the stack dump, I get the two following lines:
returned
end

Can anyone point me to the right direction?

I did not find much info on http://www.gnu.org/gcc/java


Thank you very much for any hint!
