Amay,
are you sure you're using mpicc? What you described is what you need to do
to build LAM, but that's not the same as using mpicc to build your other
mpi-compliant tools. Once you've completed your LAM build, you should have
mpicc and possibly mpif77 in /sjtu2/users/amay1975/cxm/lam/bin. You use
those wrapper compilers to build your other tools. In the makefile for
GROMACS (or in an included make.inc or similar) there should be options to
specify CC and F77. Set those to CC =
/sjtu2/users/amay1975/cxm/lam/bin/mpicc and similar for Fortran. Then
rebuild GROMACS.
