To revisit the discussion on casting last week... I just ran across
this issue:
error: cannot dynamic_cast ‘oldvar’ (of type ‘void*’) to type ‘class
Preconditioner<Number>*’ (source is not a pointer to class)
The offending code is:
PetscErrorCode __libmesh_petsc_preconditioner_setup (void * ctx)
{
Preconditioner<Number> * preconditioner =
libmesh_cast_ptr<Preconditioner<Number>*>(ctx);
.....
I only get this error in debug (obviously... since a static cast is
done in optimized).
Why can't you cast a void pointer to a class pointer dynamically?
Seems odd to me... so I'm probably doing something wrong.
