fortran makefile problem!

[milosavpejic]

I have made and compiled a programme,but the calculations are not good,because it has somehow problems with findfiff2d.o file(calulates travel-times on nodes).May be the problem is that findiff2d calls 6 other subroutines.So main=>findiff2d=>expand,sort,pass,stensilcs2d,fnod e,fside.So how to tell them to look for these 6 subroutines?
My makefile:
FC= ifort
LD = ifort
FCFLAGS = -O2 -g
LDFLAGS = $(FCFLAGS)
# Executables
main: main.o model.o findiff2d.o findnode.o timenearsrc.o readsrc.o fnode.o expand.o fside.o sort.o pass.o stencils2d.o find.o timeinterp.o timeinterp2d.o timelinear.o time1d.o timeb2d.o timec2d.o blkdat.o fd.par fd.com
$(FC) $(FCLAGS) -o main main.o model.o findiff2d.o findnode.o timenearsrc.o readsrc.o fnode.o expand.o fside.o sort.o pass.o stencils2d.o find.o timeinterp.o timeinterp2d.o timelinear.o time1d.o timeb2d.o timec2d.o blkdat.o

What should I change?

Hi.

The easiest action to take seems to change the makefile to look like:

FC= ifort
# LD = ifort
FCFLAGS = -O2 -g
LDFLAGS = $(FCFLAGS)

main: main.o sub.o
	$(FC) -o $@ $^

which, for the short files main.f and sub.f, then make will produce:

% make
ifort   -c -o main.o main.f
ifort   -c -o sub.o sub.f
ifort -o main main.o sub.o

Best wishes ... cheers, drl

Thanks drl.I am going to try now.

$(FC) -c $(FCLAGS) -o $@ $^ main main.o model.o findiff2d.o findnode.o timenearsrc.o readsrc.o fnode.o expand.o fside.o sort.o pass.o stencils2d.o find.o timeinterp.o timeinterp2d.o timelinear.o time1d.o timeb2d.o timec2d.o blkdat.o

There isn't any change,gives me:
make: `main' is up to date.

That's a status, not an error.

Do you have a specific error condition? ... cheers, drl

[milosavpejic]

So far as I know,I don't have error condition.Problem is that he does not see these variables.

What variables? ... cheers, drl

$@ $^
How do you call this up?Yes there are not variables.

Hi.

$@ $^
How do you call this up?Yes there are not variables.

If you are asking what these symbols mean, then here is a reference:

# Automatic Variables set after a rule match:
#
#   $@  Filename representing the target
#   $%  Filename element of archive member specification
#   $<  Filename of the first prerequisite
#   $?  Names of all prerequisites newer than target, space separated
#   $^  Names of all prerequisites, duplicates removed, spaced
#   $+  Same as $^, but with duplicates removed, spaced
#   $*  Stem of the target - typically file without suffix
#   GNU make, 3rd, pages 16-17

Best wishes ... cheers, drl
