That's fine, I'll try to add the amd64 subfolder to the search location.
Could you also send me your config.log (you can sent this to me  
directly for this, if you want) ?

On my systems, there is only a single warning about xine_trick_mode  
beeing deprectated, no other warnings/error.
I do belief that the warnings are a bad sign, and something goes wrong.
I'll have to make me smart about 64-bit intel stuff and  try to find a  
64-bit intel machine for debugging.

What happens is that on your platform each pointer is 64-bit wide and  
passing pointers between java and C
is a bit tricky. Could you also sent me the generated libxine_warp.c?
I don't think this is a hard problem, but it will requires beeing  
extra careful.

Are all libarares on your system 64-bit wide? what's the output of  
e.g. file /usr/lib/libxine.so.1.24.0 ?

Cheers,
  Matthias
