[petsc-users] Petsc ObjectStateIncrease without proivate header

[Pichler, Franz]

Hello,
i am using petsc in a single cpu setup where I have preassembled crs matrices that I wrap via PetSC's
MatCreateSeqAIJWithArrays  Functionality.

Now I manipulate the values of these matrices (wohtout changing the sparsity) without using petsc,

When I now want to solve again I have to call
PetscObjectStateIncrease((PetscObject)petsc_A);

So that oetsc actually solves again (otherwise thinking nothing hs changed ,
This means I have to include the private header
#include <petsc/private/petscimpl.h>

Which makes a seamingless implementation of petsc into a cmake process more complicate (This guy has to be stated explicitly in the cmake process at the moment)

I would like to resolve that by "going" around the private header,
My first intuition was to increase the state by hand
((PetscObject)petsc_A_aux[the_sys])->state++;

This is the definition of petscstateincrease in the header. This throws me an
error: invalid use of incomplete type 'struct _p_PetscObject'

compilation error.

Is there any elegeant way around this?
This is the first time I use the petsc mailing list so apologies for any beginners mistake I did in formatting or anything else.

Best regards

Franz Pichler
