>Java-GTK and Java-GNOME can be built from the same source.  We split Java-GNOME 
into Java-GTK which only contains GLib, ATK, Pango, GDK and GTK objects and 
Java-GNOME which contains all the GNOME stuff.  There is no seperate project 
called Java-GTK.</P

>The most common error of this type is caused by the fact that your system can 
not find the libraries it needs to load.  Try to run make install as root and 
ensure that the directory the two libraries (libGtkJava.so and libGNOMEJava.so) 
end up in is in the dynamic loader's path.</P

><B
>A: </B
>There are a few arguments to the configure script that
will facilitate the build.  They are --with-gcj-compile
(compile the bindings with native gcj support) and
--with-gcj-prefix (specify the root directory fo the
gcc tree which contains gcj).  If gcj is in your path
you should just be able to type "./configure --with-gcj-compile".

The build process will generate the java and jni code and
compile the java and C code.  This part of the build will
use your standard JDK and C compiler.  Once this is complete 
it will compile the java code into a shared object using
gcj with the jni feature.</P
