I have an error code while compiling my program and explicitly it has to do with the linear problem of Belos but I am not sure how to solve this problem. What did I miss? Is it something I should have included? Is it some typedef thing?

Basically, the following is my code, with matrix A and vectors x and b which are all declared by Teuchos::RCP as well.

#include <Tpetra_MultiVector.hpp>
#include <Tpetra_Core.hpp>
#include <Tpetra_Version.hpp>
#include <BelosLinearProblem.hpp>
#include <Teuchos_RCP.hpp>
#include "Tpetra_Operator.hpp"
int main(int argc, char *argv[])
{
typedef Tpetra::Vector<>::scalar_type scalar_type;
typedef Tpetra::Vector<>::local_ordinal_type local_ordinal_type;
typedef Tpetra::Vector<>::global_ordinal_type global_ordinal_type;
typedef Tpetra::Vector<>::node_type node_type;
typedef Tpetra::MultiVector<> mv_type;
typedef Tpetra::Operator<> op_type;

...

Teuchos::RCP<Belos::LinearProblem<scalar_type, mv_type, op_type>> belosProblem = 
  Teuchos::rcp(new Belos::LinearProblem<scalar_type, mv_type, op_type> (A, x, b));
}

And this is the error message I get:
