Hi Goswin,

my decision and solution was, to create a chroot like described on the 
AMD64-site. Additionally I added two entries 
in /etc/ld.so.conf.d/x86_64-linux-gnu.conf :

/var/chroot/sid-ia32/lib
/var/chroot/sid-ia32/usr/lib

and did a ldconfig.
I hope, this will not destroy my amd64-parts. I fear, the amd64-part will not 
always find the correct libs this way or do they not ?

It would be nice, if you could send me an answer, if my way is not correct.
Anyway, the 32-bit-application is running now. Other 32-bit-applications 
worked using this kind , too.

Thanks for help !

Regards

Hans
