I am getting an error when trying to compile my code in g++ using the current signature:
cannot declare member function static void Foo::Bar(std::ostream&, const Foo::Node*) to have static linkage
My question is twofold:
Signatures have always been the death of me when using C++
Edit: Here is the class header file, as well:
class Foo {
public:
Foo();
~Foo();
bool insert(const Foo2 &v);
Foo * find(const Foo2 &v);
const Foo * find(const Foo2 &v) const;
void output(ostream &s) const;
private:
//Foo(const Foo &v);
//Foo& operator =(const Foo &v);
//Not implemented; unneeded
struct Node {
Foo2 info;
Node *left;
Node *right;
};
Node * root;
static bool insert(const Foo2 &v, Node *&p);
static void output(ostream &s, const Node *p);
static void deleteAll(Node *p);
I'm guessing you've done something like:
class Foo
{
static void Bar();
};
...
static void Foo::Bar()
{
...
}
The "static void Foo::Bar
" is incorrect. You don't need the second "static
".
