Re: [Java-gnome-developer] undefined reference to `org::gnu::gtk::Entry::class$'

[Jean-Christian de R. <jc...@ec...>]

Thanks for you response, I did't know about the ABI species.

I finally get my stuff working, but the result raised two new questions:


1) I did not success removing completely the JNI stuff. For exemple I=20
can compile fine with the following command an application that only use=20
GTK:

gcj --classpath=3D/usr/share/java/gtk2-10.jar:/usr/share/java/glib0.4=20
/usr/lib/gcj/gtk2.10.jar.so /usr/lib/gcj/glib0.4.jar.so=20
--main=3Dch.eclis.ch.test.Simple -o Simple src/ch/eclis/test/Simple.java

But it run fine only if I use the command:

LD_LIBRARY_PATH+=3D/usr/lib/jni ./Simple

Without the LD_LIBRARY_PATH I get this message:

Exception in thread "main" java.lang.UnsatisfiedLinkError:=20
libgtkjni-2.10: libglibjni-0.4.so cannot open shared object file: No=20
such file or directory

I did not understand why the GCJ library still make the JNI stuff=20
required. I that normal or I still make someting wrong ?


2) If I understand correctly the packages that provids a GCJ library=20
have to install at least 2 files: a classmap *.db file (under=20
/usr/share/gcj/classmap.d/ on the Ubuntu Edgy) and a library *.jar.so=20
file (under /uar/lib/gcj/ on the Ubuntu Edgy). This is at least what I=20
can see in all packages I have, with the exception of the=20
libglade-java-gcj package that install a classmap *.db file but no=20
library *.jar.so file at all. This sound very strange to me because the=20
classmap point to a /usr/lib/gcj/glade2.12.jar.so file that is not=20
included into the libglade-java-gcj package.

This can be a Ubuntu Edgy specific issue. But I want to know if there is=20
something special I did't understand or if this is a real issue.


Thanks,
