Problem with inheritance

[10oTURfi]

After painfull debugging due weird build messages I figured that this code causes problems:

struct Castable
{
    Castable(std::string Name, int Value, int Cost) : Name(Name), Value(Value), Cost(Cost) {}
    const std::string Name;
    const int Value;
    const int Cost;
};

struct Buff : public Castable
{
    Buff(std::string Name, Attribute Attribute, int Value, int Cost) : Castable(Name, Value, Cost) 
    {
        this->Attribute = Attribute;
    }
    Attribute Attribute;
};

If I remove const-ness it will compile. Where is the problem?

These are build errors (200 lines, thus pastebin):

What is Attribute?

what ever it is you are giving a same variable name for that type.
that's the same as:

int int = int;
Attribute Attribute = Attribute;

error C2582: 'operator =' function is unavailable in 'Buff'
says that you try to use
Buff b, c;
b = c;
(or you try to use vector< Buff > )

without existing operator=
when members are const - you can't change them, so default operator= can't be created

@codekiddy
thats was typo :)

@Ivan Sidarau
Yeah, I tried to use vector<Buff>, but I do not understand how does that try to change them.
