I am trying to add energy equation in the solver InterIsoFoam. The in-built solver calculates rhoPhi as

rhoPhi = advector.getRhoPhi(rho1f, rho2f);

Since Energy equation is also added so i am trying to calculate rhoCpPhi as

rhoCpPhi = advector.getRhoCpPhi(rho1f, rho2f);

I have defined getRhoCpPhi in isoAdvector.H as:

// Return Heat flux
        tmp<surfaceScalarField> getRhoCpPhi
            (
                const dimensionedScalar rho1,
                const dimensionedScalar rho2,
            const dimensionedScalar cp1,
                const dimensionedScalar cp2
            ) const
            {
                return tmp<surfaceScalarField>
                (
                    new surfaceScalarField
                    (
                        "rhoCpPhi",
                        (rho1*cp1 - rho2*cp2)*dVf_/mesh_.time().deltaT() + cp2*rho2*phi_
                    )
                );
            }

The library gets compiled but while compiling the solver, it displays:

What might i be missing?
