Nice to hear about your progress! :-)
Due the fact that Kaffe uses libtool you will never get a "real" static 
executable, but you can only have a "semi-static" executable that will NOT 
use the Linux dynamic library loading but will make all this works on its 
own (IOW: kaffe-bin itself loads libnative and extract the right function 
pointer). I'm not an expert of libtool (I have just some minor experience 
with Kaffe and other open source project that use this tool) so, anyone 
that knows libtool better that me can correct me! :-)

You have find a way to tell to Kaffe where to find this library (which is 
what the original kaffe bash script does)... I run kaffe-bin with the 
following msh script (that I call 'java'):

#!/bin/msh
env KAFFE_NATIVE_LIBRARY_DIR=/kaffe/jre/lib/arm KAFFE_LIBDIR=/kaffe/lib \
LIBRARY_PATH=/kaffe/jre/lib/arm \
LD_LIBRARY_PATH=/kaffe/jre/lib/arm \
/kaffe/jre/bin/kaffe-bin  $*

Please note that I used /kaffe as prefix when configuring kaffe.

Best Regards,

Andrea
