fortran debugging problem

I have compiled code but it doesn't work properly.My makefile:

FC= ifort
LD = ifort -align all
FCFLAGS = -O0 -g -ipo -traceback -warn noalign
LDFLAGS = $(FCFLAGS)

# Executables
nray: main.o findnode.o plots.o segmnt.o empty.o aldone.o erase.o pcolor.o box.o plot.o axtick.o axis.o line.o pltsrcbox.o find.o dot.o开发者_如何学运维 grad.o intersect.o straight.o backproj.o ddtime.o kernel.o resolution.o plotnd.o bndinterpret.o time.o $< $(INCS)
    $(FC) $(LDFLAGS)  $(FCFLAGS) -o nray main.o findnode.o plots.o segmnt.o empty.o aldone.o erase.o pcolor.o box.o plot.o axtick.o axis.o line.o pltsrcbox.o find.o dot.o grad.o intersect.o straight.o backproj.o ddtime.o kernel.o resolution.o plotnd.o bndinterpret.o time.o $< $(INCS)
main.o:main.f ray.par ray.com
    $(FC)  $(FCFLAGS) -c main.f

So if I want to see why backproj.o is not working,what should I do?

You are reading past the end of the file:

/home/milenko/fast/ray/num.cell

this is either because num.cell isn't long enough or your reading routine isn't stopping at the right place. The offending read is at line 226 of main.f or at least called there.

Can't really say much more without seeing some code.

It seems unlikely the problem is with backproj.f (doesn't sound like the sort of routine which should/will be reading a file) but that's just a guess based on the names of your routines.

You are getting and end of file error from the fortran runtime library trying to read the file num.cell. The first step should be to check whether the contents of that file are valid.
