Is the software also built on the wheezy or jessie system before attempting to run it, or is it built elsewhere? What is the exact error output that you get? What is the output of 'ldd /path/to/the/program'? Is it written in C++?

Without knowing precisely what resources the software needs, though I cannot be certain if it is suitable. In any event, building a chroot environment is as simple as installing debootstrap and then doing this: sudo debootstrap unstable /path/to/chroot After that, you can install your program under that directory and run it with: sudo chroot /path/to/chroot /inside/chroot/path/program Or, so work interactively in the chroot: sudo chroot /path/to/chroot /bin/bash The debootstrap utility knows about the Debian releases as well as the Ubuntu releases and should be able to set up either. Though, you may need to install an updated debootstrap for setting up chroots for the latest Debian or Ubuntu releases. Regards, -Roberto -- Roberto C. Sánchez
