fortran makefile problem!

[Milentije]

This is what I get when I try to make my code:
f77 -O2 -o eik eik.o eik.para velo vel1.dat eik.out
/usr/bin/ld.real:eik.para: file format not recognized; treating as linker script
/usr/bin/ld.real:eik.para:1: syntax error
What is the problem?
My makefile:
F77=f77
FLAGS= -O2
# executables
eik: eik.o eik.para velo vel1.dat eik.out
$(F77) $(FLAGS) -o eik eik.o eik.para velo vel1.dat eik.out
# object files
eik.o: eik.f eik.para velo vel1.dat eik.out
$(F77) $(FLAGS) -c eik.f -o eik.o
# dependancies
eik.o: eik.para velo vel1.dat eik.out
