Invalid pair style (eam, 20 Aug 2011)

Dear lammps users,

That's what I have with the recent version (downloaded via svn)
  for a benchmark file:

./lmp_serial < in.eam
LAMMPS (20 Aug 2011)
Lattice spacing in x,y,z = 3.615 3.615 3.615
Created orthogonal box = (0 0 0) to (72.3 72.3 72.3)
   1 by 1 by 1 processor grid
Created 32000 atoms
ERROR: Invalid pair style

was something changed with regards to declaration of pair_style eam?

Kind regards,
Denis Davydov

have you checked whether the manybody package is installed?

you can try out the new -help switch to lammps that will dump
the list of compiled in styles.

the svn versions by default don't compile in _any_ optional packages.

Dear Axel,

That was exactly the case, manybody was not installed.
Thank you for your help.

Kind regards,
Denis
