integrating petsc code into non petsc code

[Matt Funk]

If i am missing the question please ignore this email,

but i think you are using your own make files (i.e. NOT petsc make system?).
If so, i am doing the same. Here is what you need during compilation:
    
PETSC_INC_DIR= -I$(PETSC_DIR)/include -I$(PETSC_DIR)/bmake/$(PETSC_ARCHITECTURE)
PETSC_LIB_DIR= -L$(PETSC_DIR)/lib/$(PETSC_ARCHITECTURE)
PETSC_LIBS= -lpetsccontrib -lpetscts -lpetscsnes	-lpetscdm -lpetscksp -lpetscmat -lpetscvec -lpetsc

Petsc make does this automatically for you i believe.
Again, if i missed the question please ignore.

matt

ps: i am on petsc-2.3.3-p15
