Kind of.  I grepped for "libgtkpeer" and it looks like the library is
properly found, opened, read etc...  Though I am not quite sure why
do I see a the end SableVM being "killed by SIGINT" !

Can you add --enable-debugging-features to 'sablevm's ./configure,
remove any --with-threading=... option, and recompile reinstall it?
(no need to touch sablevm-classpath or any other software)

Do you get any additional information (ie. a failed assertion) when
ran normally?


There's also other things I have not asked you about yet, i.e.
does the app you're trying to run on ARM run when you use SableVM
on an x86?


I also went thru all the code involved in initiating gtkpeers
and then loading a library, up to sablevm native method 
Java_java_lang_VMRuntime_nativeLoad in
src/libsablevm/java_lang_VMRuntime.c

I do not know if you have gdb running reliably on your Taurus
(I remember there were problems with it sometimes), so if I were
you, I'd put in the above function a few 'printf(); fflush(NULL);'
statments that would show with what parameters its called,
what is the control flow inside and where exactly it fails!


For now I suspect a libtool problem that we might need to work
around (though the strange thing is that the .so library actually
is found, opened and read).


It might seem a vague advice, but you should not give up.  It's
probable we're very near finding the exact problem.  Just a little
more patience :-)
