TNG is a 32-bit application.
It will run on a 64-bit machine, but requires 32-bit libraries on the 64-bit system.
We can't provide safely libraries for all Linux distribution. With Ubuntu / Debian, we previously installed the ia32-libs package to get the 32-bit library support. On newer Ubuntu / Debian, it supports multiarch, and then the following 32-bit packages are required to install those libraries:
libstdc++6:i386
libuuid1:i386
zlib1g:i386
TNG should not requires libraries besides the basic ones (libc, libdl, libpthread, libz, libuuid, etc.)
