cannot convert '_p_Vec* const' to '_p_VecScatter*' for argument '1' to 'PetscErrorCode

[Anirban Chatterjee]

Hi,

I am trying to use Steve Wright's OOQP with PETSc support and get this 
error:
cannot convert '/_p_Vec/* const' to '/_p_VecScatter/*' for argument '1' 
to 'PetscErrorCode

Can anyone tell me why I am getting this error. I am getting this error 
in the VecScatterBegin function where the first argument type is Vec.

Thanks,
Anirban
