[petsc-users] using makefiles

[Satish Balay]

Normally you would do:


CPPFLAGS = I$(OLYMPUS_INC_DIR) -I$(FEI_DIR) -DPROM_HAVE_METIS -DPROM_USE_PETSC -DPROM_NO_FEI -DPROM_HAVE_SILO # -I$(SILO_INC)
FPPFLAGS   = -fdefault-integer-8

include ${PETSC_DIR}/lib/petsc/conf/variables
include ${PETSC_DIR}/lib/petsc/conf/rules

[CFPPFLAGS/FPPFLAGS are used for compile - and CFLAGS/FFLAGS are used for both compile and link]
