Here is code sample which reproduces my problem:
template <typename myType>
class Base {
public:
Base() {}
virtual ~Base() {}
protected:
int myOption;
virtual void set() = 0;
};
template <typename InterfaceType>
class ChildClass : public Base < std::vector<InterfaceType> >
{
public:
ChildClass() {}
virtual ~ChildClass() {}
protected:
virtual void set();
};
template <typename InterfaceType>
void ChildClass<InterfaceType>::set()
{
myOption = 10;
}
My usage in main()
:
ChildClass<int> myObject;
I get the following error (gcc 4.4.3 on ubuntu):
‘myOption’ was not declared in this scope
If my ChildClass would be without new template parameter this would work fine, i.e.:
class ChildClass : public Base < std::vector<SomeConcreteType> >
Edit
I've managed to solve it, if my set method looks like:
Base<std::vector<InterfaceType> >::myOption = 10;
It works fine. Still though not sure why I need to specify all template parameters.
