I am trying to compile a parallel fortran package in a beowulf cluster,
my compiler is Portland Fortran90. I got a very strange problem, following is
error message, does anybody know what's the problem?

make
pgf90 -O -lfmpich -lmpich skgen.f -c
pgf90 -O -lfmpich -lmpich zxssq.f -c
pgf90 -O -lfmpich -lmpich ludec.f -c
pgf90 -O -lfmpich -lmpich luelm.f -c
pgf90 -O -lfmpich -lmpich uertt.f -c
pgf90 -O -lfmpich -lmpich func.f -c
pgf90 -O -lfmpich

You didn't link the mpi library when make your executable file.
You need add -lfmpich -lmpich options in your makefile

Thank you for your reply. However, I think I linked mpi library. See the
message from making executable file
pgf90 -O -lfmpich -lmpich skgen.f -c
pgf90 -O -lfmpich -lmpich zxssq.f -c
pgf90 -O -lfmpich -lmpich ludec.f -c
Is this the correct way to link?
The makefile which is related:
SHELL=/bin/csh
#
CFT= pgf90
LDR= pgf90
# On IBM set all constants to double precision (Alpha does this automatically)
FFLAGS = -O -lfmpich -lmpich
# FFLAGS = -O -L/usr/pgi/linux86/lib/libpgf90.a
# FFL

When you generate those .o file, such as
skgen.o, zxssq.o and ludec.o, it's not necessary to link those mpi libraries.
But you do need it when you link all these .o files into your executable
files. So this line matters:
pgf90 -o skfit2 skgen.o zxssq.o ludec.o luelm.o uertt.o func.o diag.o myhtdi.o
myred.o mytql2.o fermi4sk.o hsort.o tnewef.o matri.o setup.o rotate.o
quadroot.o symmeg.o input.o input1.o mapk.o multatoms.o search2.o shifttrue.o
mpifake.o
Change the line following skfit2 to
skfit2
