[kaffe] HelloWorld > NullPointerException > Aborted

Hi all.

I'm trying to run a HelloWorld on my arm but it craches anyway.

I use the standard gcc cross-compiler and configure kaffe as this :

KAFFEH=/my-x86-build/kaffe-1.1.6/kaffeh/bin/kaffeh \
./configure \
--host=arm-linux \
--build=i686-linux \
--disable-alsatest --disable-esdtest \
--enable-pure-java-math \
--with-jikes \
--without-classpath-gtk-awt \
--without-alsa --without-esd \
--with-kaffe-awt-qt --with-qtdir=$QTDIR \
--with-threads=unix-jthreads \
--enable-xscale

This kind of build works on my scratch-box, but not on my arm.

I ever tried unix-pthreads, unix-jthreads, engine intrp, engine jit, with and
without xscale option but no way to work om my arm :(

My arm uname is : armv5tejl

Here is various debugging lines on my arm:

What is the problem ?


I tried to use libffi too, but when configuring kaffe, it says to me,
unable to find libffi.
Does my libffi have to be built for x86 or arm ?
I tried to put both in my LD_LIBRARY_PATH 
or by --with-includes & --with-libraries for the configuration 
but none of them work.

Regards,

Chrisotphe
