No, all libs are not hardcoded ( as I suppose).

In the required application, there is no configuration, where I can point the

The application is called "X-Plane", it is is a famous flight simulator, but
closed source. Of course it is not in Debian, as the license does not allow
it.
Anyway, if I am understanding your words correctly, then the 32-bit
applications will always know, which lib it has to use, if it is available
and can be found on the system ?
So my way using a chroot is correct and will not cause trouble. Nice to hear
this ! This is really great !
Thank you very much for your help !
