Uniform initialization doesn't work for initialization parent object in ctor

Question

Suppose I have a struct:

struct A 
{
    int i;
};

I can init it as:

A a{1};

Now I have a derived class:

struct B : public A
{
     B(int _i) : A{_i} {};
};

But I have a compilation error in B struct ctor:

error: no matching function for call to ‘A(<brace-enclosed initializer list>)’

Compiler is gcc-4.6 (SUSE Linux) 4.6.3

Answer 1

There is nothing wrong with your code; it is simply that your compiler doesn't support all of the required C++11 features.

Your constructor compiles fine with gcc 4.7.0.
