Hello ,
I am trying to pass a TVECTOR3 as an argument to function created by me ,
and the thing seems not to work. I work on RedHat Linux v7.2 and the
3.02/07 version of ROOT.
The code looks like
gSystem->Load("libPhysics");
Float_t my_func(TVector3 p_one, TVector3 p_two);
void main()
{
gSystem->Load("libPhysics");
......
TVector3 *a = new TVector3(5.0, 6.0, 7.0);
TVector3 *b = new TVector3(2.0, 5.0, 2.0);
Float_t c = my_func(a,b);
.......
}
Float_t my_func(TVector3 *p_one, TVector3 *p_two)
{
gSystem->Load("libPhysics");
Float_t k1 = p_one->Mag();
Float_t k2 = p_two->Mag();
return sqrt(k1*k2);
}
The error i get is :
Error: Illegal Assignment to an undeclared symbol TVector3*p_one FILE:testing.C LINE:20
Error: Illegal Assignment to an undeclared symbol TVector3*p_two FILE:testing.C LINE:20
*** Interpreter error recovered ***
What do i miss?
Thanks in advance.
