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 On Tuesday 21 April 2009, Pierre-Yves Aquilanti wrote: > Hello everyone, > > i'm trying to integrate petsc code into one big software. petsc would act > as a solver for the program. > The way that i try to integrate my petsc code is like that: > > ######################## > program myoldnonpetsccode > > use mymodule > > implicit none > > call process_petsc > > end myoldnonpetsccode > ######################## > module mymodule > implicit none > > #include "finclude/petsc.h" > > contains > subroutine process_petsc > call PetscInitialize(PETSC_NULL_CHARACTER,ierr) > > call PetscFinalize(ierr) > > end subroutine process_petsc > end module mymodule > ############### > > > The compiler used for petsc, mpich and the non-petsc code is the same > (PGI).
