You don't say which MACHINE file you were using, which would have helped.

Look in Machine.g77_mpich (even if you are using something different). The
followoing lines determine which cpp is used:

# CPP is the cpp for this machine
setenv CPP "/lib/cpp -traditional -I$MPICH_INCLUDE"

You may need to adjust these for your environment. [In particular, if you
are using Machine.g77, and "cpp" is not in your PATH, you will need to
modify the corresponding line in that file.]

"Traditional" Unix/Linux systems put cpp into /lib, but this never really
made any sense, and some distributions (like current RedHat Linux)
put it in /bin. This leads to confusion, and even the different files
in amber7/src/Machines are not all consistent in what they assume.

Some other comments (for you or others thinking about this):

(1) Don't try to do a parallel install without doing a single-processor
install first.

(2) As the manual indicates, there is generally no reason to compile
all of amber on a parallel machine: see the "install.parallel" target
of amber7/src/Makefile. Only compile the codes you are planning to use
on the parallel machine.

...good luck...dac
