Subject: Incompatible types for array conversion

Message-ID: <d189dbFb5b2U1@mid.individual.net> (raw)
I have a generic vector package:
generic
dim: positive;
type Real is digits <>;
package Vectors is
type Vector is array (1..dim) of Real;
function "*" (a: Vector; b: Real) return Vector;
end Vectors;
In another package I want to model the definition of a (physical)
position vector by its direction and module:
package Basic is
type Real is new Interfaces.IEEE_Float_64;
type Length is new Real;
package Positions is new Gen.Vectors (3, Length);
package Directions is new Gen.Vectors (3, Real);
subtype Position is Positions.Vector;
subtype Direction is Directions.Vector;
function "*" (l: Direction; r: Length) return Position;
end Basic;
Now my attempt to define this function:
function "*" (l: Direction; r: Length) return Position is
begin return Positions."*"(Position(l), r); end "*";
gets me the error message in the subject line.
Do I have to convert the vector element by element in a loop or is there
a more elegant way?
