PETSC headers

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

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}
 
 --------------------------------------


If I use that is says:

make: *** No rule to make target `debug/main.o', needed by `all'.  Stop.
