I see the problem. Generic_Real_Arrays is the name of the parent generic
package; that's not a concrete package, so it can't be used here.

This compiles:
with Ada.Numerics.Generic_Complex_Arrays;
with Ada.Numerics.Generic_Complex_Types;
with Ada.Numerics.Generic_Real_Arrays;
generic
type Real is digits <>;
with package Real_Arrays is new Ada.Numerics.Generic_Real_Arrays (Real);
with package Complex_Types is new Ada.Numerics.Generic_Complex_Types (Real);
with package Complex_Arrays is new Ada.Numerics.Generic_Complex_Arrays (Real_Arrays, Complex_Types);
package Extensions is
function Eigenvalues (A : Real_Arrays.Real_Matrix) return Complex_Arrays.Complex_Vector;
end Extensions;
Is there some reason you want Extensions to be a child of Generic_Real_Arrays?
