Hi folks, I'm having a problem with using a "using" directive to use a type in a base class in a derived class. A typedef of the same thing does work however:
class other
{
public:
typedef int foo;
};
template <typename T>
class base
{
public:
T something;
typedef other::foo bar;
};
template <typename T>
class derived : public base<T>
{
using base<T>::bar; // This does not work.
//typedef other::foo bar; // This does work.
void breaks()
{
bar baz;
baz = 4;
}
};
int main()
{
derived<int> var;
}
% g++ -Wall -pedantic -o test test.cc
test.cc: In member function ‘void derived<T>::breaks()’:
test.cc:23: error: expected `;' before ‘baz’
test.cc:24: error: ‘baz’ was not declared in this scope
test.cc: In function ‘int main()’:
test.cc:30: warning: unused variable ‘var’
Is this an issue with GCC, or am I using incorect syntax here?
Many thanks,
Roger
