New page

The following is an example Makefile that compiles an object-oriented CFD solver that uses Petsc.

The example program is a Laplace solver.

<syntaxhighlight lang="make">

# To begin with, a default target must be defined.
# The default is the driver contained in the
# Laplace.cc file.

default: Laplace

# Define the path to the Petsc install directory

PETSC_DIR=/Users/charles/pkg/petsc-3.0.0

# Include Petsc-defined variables

include ${PETSC_DIR}/conf/base

# These rules define how to compile the cc file.
# Then the Makefile links the executable to
# the output (.o file).

SRC_FILES = \
BoundaryCondition.cc \
BoundaryConditionFactory.cc \
Field.cc \
FileIO.cc \
JacobiSolver.cc \

OBJ_FILES = $(SRC_FILES:%.cc=%.o)

DRIVER_SRC = \
Laplace.cc \

# Make macros:
# $< = first input
# $^ = inputs
# $@ = outputs

# Define a make target for non-Petsc source files: any .cc file is compiled into a .o file

# Define make target for the GMRES solver class, which uses Petsc

# Define make target for both Petsc and non-Petsc objects

objects: $(OBJ_FILES)

# Define make target for linking the objects with the driver
# The ${CLINKER} variable is defined by Petsc. The "-" prefix is also very important.
# If you compile Petsc to use C, ${CLINKER} is mpicc. If you compile Petsc to use C++, ${CLINKER} is mpic++.
