Exception: Requested binding {"symbol": "IntTools_CArray1OfReal"} does not exist!

When I create a Custom Builds,and add a symbol IntTools_CArray1OfReal,complilated the yml and it report exception like that:Exception: Requested binding {"symbol": "IntTools_CArray1OfReal"} does not exist!
But I saw the opencascade.full.d.ts installed from npm,it has the IntTools_CArray1OfReal class.So How I custom builds with the class?
the code in opencascade.full.d.ts is:

export declare class IntTools_CArray1OfReal {
  Init(V: Quantity_AbsorbedDose): void;
  Resize(theNewLength: Graphic3d_ZLayerId): void;
  Destroy(): void;
  Length(): Graphic3d_ZLayerId;
  Append(Value: Quantity_AbsorbedDose): void;
  SetValue(Index: Graphic3d_ZLayerId, Value: Quantity_AbsorbedDose): void;
  Value(Index: Graphic3d_ZLayerId): Quantity_AbsorbedDose;
  ChangeValue(Index: Graphic3d_ZLayerId): Quantity_AbsorbedDose;
  IsEqual(Other: IntTools_CArray1OfReal): Standard_Boolean;
  delete(): void;
}
