Dear Rooters,

I am trying compile this small peace of code,

#ifndef PRIVATEMATH_H
#define PRIVATEMATH_H

#include <TROOT.h>
#include "TMath.h"
#include "Math/IFunction.h"
#include "Math/SpecFuncMathMore.h"
#include <math.h>

    using namespace ROOT::Math;
    using namespace std;

    double m_P( unsigned l, double cos_theta){

         double theta = acos( cos_theta );
         return sqrt(2*TMath::TwoPi())* sph_legendre( l, 0, theta  );

    }

#endif

but i got these errors:
