need help with makefile

[P. Aaron Lott]

Thanks for this information. I think I setup things almost right, but  
something is causing preprocessor to complain. The errors it is  
giving are referring to lines of my main program file that doesn't  
exist.

I would appreciate any recommendations about how to fix this problem.  
I've list some of the details of my setup below.

Thanks,

-Aaron



e.g.

macbeth% make unsteady_ex
/usr/local/mpich-1.2.5.2/bin/mpicc -I/Users/palott/research/codes/ 
petsc/petsc-2.3.2-p8 -I/Users/palott/research/codes/pets
c/petsc-2.3.2-p8/bmake/darwin-mpich-g -I/Users/palott/research/codes/ 
petsc/petsc-2.3.2-p8/include  -I/usr/local/mpich-1.2.
5.2/include        -E -traditional-cpp __unsteady_ex.c | /usr/bin/ 
grep -v '^ *#' > __unsteady_ex.F
/usr/local/mpich-1.2.5.2/bin/mpif90 -c  -I. -g  __unsteady_ex.F -o  
unsteady_ex.o
"__unsteady_ex.F", line 965.2: 1515-019 (S) Syntax is incorrect.


But there are only 207 lines in this file.....



In my current makefile I have

F90=mpif90
F77=mpif77
F77FLAGS= -C -g -qdpc -qautodbl=dbl4 -qinitauto -Wl,-framework - 
Wl,vecLib
FLAGS=  -C -g  -qdpc -qautodbl=dbl4 -qinitauto -Wl,-framework -Wl,vecLib


EXENAME = unsteady_ex
CMD:=EXENAME

SOBJS = mpi.o  quicksort.o routines.o binsort.o  coordinates.o  
comm_maps.o elements.o globaldata.o sem.o comp_inv.o d1ops.o maps.o   
pardss.o dss.o stiffness.o convection.o Mass.o  pressure.o buildU.o   
wind.o forcing.o boundary_cond.o  navier_stokes.o runge_kutta.o   
out.o gmres.o pcg.o stream.o uzawa.o print_matrices.o projection.o  
bdf.o  stokes_solvers.o  initialize_mpi.o unsteady_ex.o


$(CMD)  : $(SOBJS)
	-${FLINKER} $(FLAGS) -o $(EXENAME) $(SOBJS)   $(PETSC_SYS_LIB)


mpi.o		: ../Comm/mpi.f90 		;$(F90) $(FLAGS) -c ../Comm/mpi.f90
gmres.o		: ../Solvers/gmres.f90		;$(F90) $(FLAGS) -c ../Solvers/ 
gmres.f90
etc.... for all the object files except unsteady_ex.o

unsteady_ex.F is my main program.

In the example you gave, ex1f.F would be the main program, and at the  
top of the file it would have the statement:

#include "include/finclude/petsc.h"

So in my case, I've put that in the top of my unsteady_ex.F
