Following code failed. class X { int value ; friend class Y ; } ; class Y { public : template < typename T > static auto f(T t) -> decltype( t.value ) { return t.value ; // OK. Y is a friend of X. } } ; int main() { X x ; Y::f(x) ; // gcc issues error } The error message is In function 'int main()': error: 'int X::value' is private error: within this context It looks like access checking is done in the main rather than Y::f<X>. ^ permalink raw reply [flat|nested] 6+ messages in thread
