[dune-fem] Errors with petsc in example-solvers, dune-fem-howto

[Sacconi, Andrea]

Hi all,

I just installed petsc 3.5.0, and I was curious to see how to use it with dune-fem-1.4.0.
So I tried to play with one of the examples in the howto, but unfortunately I got this compilation error:

In file included from main.cc:43:0:

                                                   ^

     inline void KSPSetOperators (KSP ksp, Mat Amat, Mat Pmat, MatStructure flag ) { ErrorCheck( ::KSPSetOperators( ksp, Amat, Pmat, flag ) ); }

Is the howto currently working?
If someone of you does manage to use it, which version of petsc do you use? Could it be a problem of compatibility?

Thanks in advance!
Andrea
