I sometimes have issues running a 32bit program under Linux X64.
When you run ldd it reports that it’s not a dynamic executable
# ldd /usr/bin/snx not a dynamic executable
However if you run file, you do see that it is.
# file /usr/bin/snx /usr/bin/snx: setuid ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped
You can confirm that you are running 64 bit Linux
# uname -i x86_64
To fix this you need to install 32 bit libraries. On Fedora you can install them using
dnf install /lib/ld-linux.so.2 libX11.so.6 libpam.so.0 libstdc++.so.5
And on Debian
apt-get update apt-get install lib32z1 lib32ncurses5 libstdc++5:i386
Worked for me.
