Hi Benny,
Your question is off-topic for the GCC-help forum. Your question is a
general C++ question. I do not say this to chastise you, but to help you
get your questions answered faster and accurately in a more appropriate
forum.
That being said...
The B::a routine hides the other signatures of the overloaded A::a routines.
If you want to bring the A::a routines forward, you need to explicitly say
so.
You do that by specifying 'using A::a;' in class B:
class B : public A
{
public:
using A::a;
void a()
{
}
};
