[dune-pdelab] petsc test example in pdelab

[Jizhou Li]

Hi,
I installed petsc and linked with dune-pdelab and compiled the file /dune/pdelab/test/testpoisson-petsc.cc. But, when I tried to run the code I got following error message.
Is there something wrong with petscbackend in dune-pdelab?

Thanks

Jizhou
