Bug ID: 60265
Summary: [C++11] using-declarator of enumerator fails if fully
qualified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roger.ferrer at bsc dot es
Hi,
a using-declarator the nested-name of which includes an enumerator-name fails,
as g++ seems to expect only namespace-names at this point.
This seems a specific lookup problem of the using-declarator. Other
qualified-ids, seem to work, as shown in the snippet below.
// -- enum.cc
namespace A
{
enum E { V };
}
namespace B
{
void f1()
{
int x;
x = A::E::V; // OK
x = A::V; // OK
}
void f2()
{
using A::V; // OK
int x;
x = V;
}
void f3()
{
using A::E::V; // ERR (but should be OK)
int x;
x = V;
}
}
// -- end of enum.cc
$ ~/soft/gcc-experiment/gcc-install/bin/g++ -std=c++11 --version
g++ (GCC) 4.9.0 20140218 (experimental)
$ g++ -std=c++11 -c enum.cc
enum.cc: In function ‘void B::f3()’:
enum.cc:24:21: error: ‘A::E’ is not a namespace
using A::E::V; // ERR
^
enum.cc:26:13: error: ‘V’ was not declared in this scope
x = V;
^
enum.cc:26:13: note: suggested alternative:
enum.cc:3:14: note: ‘V’
enum E { V };
Kind regards,
