Subject: Antwort:  template friend declaration not recognized





Hi all,

I'm responding to the "Comments From lerdsuwa at gcc dot gnu dot org
2004-11-27 16:19":

I do not think that the cited standard rule (11.4/2) matches my example
because the nested class C1::S1 uses a name of its surrounding class -
namely C1::T_PAR. For the definition of this name class C1 in turn
is referring to a name of class C2 - namely C2::T_PAR_TYPE. And
class C2 grants class C1 access to its private names.


Best regards,
W. Roehrl

Not a bug.  You are using TPAR inside the class C1::S,
however, only C1 is a friend of C2.  This is the relevent section
of C++ standard (section 11.4 paragraph 2):

  ... the declarations of members of classes nested within
  the friend class cannot access the names of private and
  protected members from the class granting friendship. ...

and the example in the same section:

  class A {
class B {};
friend class X;
  };
  class X : A::B {   // ill-formed: A::B cannot be accessed
 // in the base-clause for X
A::B mx; // OK: A::B used to declare member of X
class Y : A::B { // OK: A::B used to declare member of X
  A::B my;   // ill-formed: A::B cannot be accessed
 // to declare members of nested class of X
};
  };
