LAMMPS (21 Feb 2017) ERROR: Unknown pair style eam/alloy/opt (../force.cpp:244)

Good afternoon!

I try to perform simulation of crystallization of alloy with LAMMPS package.

The initialization file and the file with potential are here: in-file, potential.

However, the execution fails with the following output:

…/…/src/lmp_g++_openmpi < …/in.AlNi.prism_npt-1
LAMMPS (21 Feb 2017)

My system information:

lsb_release -idrc && echo Kernel Release: uname -r
Distributor ID: SUSE LINUX
Description: openSUSE Leap 42.1 (x86_64)
Release: 42.1
Codename: n/a
Kernel Release: 4.1.38-47-default
gcc --version | grep ‘gcc’
gcc (SUSE Linux) 4.8.5

This LAMMPS version was installed from GitHub.

I also have an older version of LAMMPS installed from repository,

lammps -help | grep ‘LAMMPS’
LAMMPS (12 Apr 2013)

It does run the simulation, but returns incorrect results. As I know, this was fixed at later versions in 2016 year, so I need to use recent versions of LAMMPS.

Could somebody help to overcome the error, obtained with the later version on my system, please?

Thank you in advance.
