PETSC headers

[Satish Balay]

PETSc is installed with MPI, LAPACK - and can be installed with PARMETIS
[which has metis.a].  So there is no reason to have a non-petsc
makefile.

And you can't use a different MPI than what PETSc is installed with.

The simplest makefile would be:

--------------------------------------
CFLAGS           =
FFLAGS           =
CPPFLAGS         =
FPPFLAGS         =
CLEANFILES       =

include ${PETSC_DIR}/bmake/common/base

ex1: ex1.o  chkopts
	-${CLINKER} -o ex1 ex1.o  ${PETSC_LIB}
	${RM} ex1.o
--------------------------------------

Where 

CLEANFILES - is additonal files you want to get deleted with 'make clean'
CPPFLAGS, FPPFLAGS are additional user required preprocessor flags [for eg -DFOOBAR]
CFLAGS,FFLAGS are additional user required compiler flags [perhaps like -r8]

If you wish to just use PETSc as installed [without parmetis] - and
'metis' required by your code, use:

--------------------------------------
SOURCE_DIR = ???
METIS_INC  = -I$(SOURCE_DIR)/metis/include
METIS_LIB  = $(METIS_DIR)/libmetis.a
EXECUTABLE = examples/ex
SOURCE_OBJ = ex1.o

CFLAGS           = 
FFLAGS           =
CPPFLAGS         = $(METIS_INC)
FPPFLAGS         =
CLEANFILES       = $(EXECUTABLE)

include ${PETSC_DIR}/bmake/common/base

all: $(SOURCE_OBJ)  chkopts
	-${CLINKER} -o $(EXECUTABLE) $(SOURCE_OBJ) $(METIS_LIB)  ${PETSC_LIB}

--------------------------------------
