Hi Chomsri,
What has happened is that when you have installed and configured mpich it
has looked for fortran compilers on your system and picked up the absoft
compiles and is using these. The Absoft compilers do not work properly with
Amber.
Try the following:
1) Resinstall MPICH manually specifing the compilers
e.g ./configure -prefix=/usr/local/mpich-1.2.1 -fc=g77 -cc=gcc
Then do make / make install etc.
Then try recompiling amber. Make sure you do a make clean in ./amber6/src
first.
if this doesn't work try replacing all occurances of mpif77 and mpicc in the
machine file with g77 and gcc respectively.
Also, I would ensure that /usr/local/mpich-1.2.1/bin is in your path.
I also trust you uninstalled v1.2.0 of mpi? If not then you need to check
which one is favoured as far as libraries etc go.
e.g which mpirun
Hope this helps
All the best
Ross
