As i mentioned in another issue: Compiler should be able to deduce overloading here. But if it doesn't - i would try to move poly_postsmooth() and poly_presmooth() functions to partially specialized class/struct with general template throwing "not supported" error.

Something like

template<class T_Config>
struct poly_smooth
{
    static void poly_postsmooth(const Matrix<T_Config> &A, const Vector<T_Config> &B, Vector<T_Config> &C, cusp::relaxation::polynomial<typename T_Config::MatPrec, typename T_Config::MemSpace> &poly)
    {
        FatalError("Mixed precision is not supported for scalar matrix type", AMGX_ERR_NOT_IMPLEMENTED);
    }
    static void poly_presmooth(const Matrix<T_Config> &A, const Vector<T_Config> &B, Vector<T_Config> &C, cusp::relaxation::polynomial<typename T_Config::MatPrec, typename T_Config::MemSpace> &poly)
    {
        FatalError("Mixed precision is not supported for scalar matrix type", AMGX_ERR_NOT_IMPLEMENTED);
    }
}

template<AMGX_MemorySpace t_memSpace, AMGX_IndPrecision t_indInt>
struct poly_smooth<TemplateConfig<t_memSpace, AMGX_vecDouble, AMGX_matDouble, t_indInt>>
{
    static void poly_postsmooth(...){...};
    static void poly_presmooth(...){...};
}

template<AMGX_MemorySpace t_memSpace, AMGX_IndPrecision t_indInt>
struct poly_smooth<TemplateConfig<t_memSpace, AMGX_vecFloat, AMGX_matFloat, t_indInt>>
{
    static void poly_postsmooth(...){...};
    static void poly_presmooth(...){...};
}

...
poly_smooth<T_Config>::poly_postsmooth(...);
...
