MPI platform

I would appreciate any help regarding installing MPI to run LAMMPS in my laptop. I tried but could not figure out. I am getting MPI_variables error while running the make file even after I install MPICH2 package in my Ubuntu platform.

Looking forward to some advice,

That's really an MPI question, not a LAMMPS one. I presume
you went to the MPICH WWW site and dowloaded a tarball
and followed the instructions? I have no issue building MPICH
on a Linux box. They may even have RPMs or pre-packaged distributions
where you don't have to build anything.
