initializing static stdlib containers

If I wanted to count how many objects of a class I make, I could write

Code:

// header.hh

class bob
    {
    public:
        bob() ;
    private:
        static int bobCount_ ;
    }

and then a file with the code and initialization

Code:

// code.cc

#include "header.hh"

bob::bobCount_ = 0 ;

bob::bob()
    {
    bobCount_++ ;
    }

So here is the question. Say I want to instead add each object to a stdlib set? Then my header file is

Code:

// header.hh

#include <set>

class bob
    {
    public:
        bob() ;
    private:
        static std::set<bob*> bobSet ;
    }

and then a file with the code and initialization

Code:

// code.cc

#include "header.hh"

bob::bobSet = ????

bob::bob()
    {
    bobSet.insert( this ) ;
    }

So how do I initialize the set container class? The row of question marks doesn't work!

You can just write in code.cc:

Code:

std::set<bob*> bob::bobSet;

Thanks, that definitely works. I never would have come up with the syntax, although now that I've seen it, I understand where it comes from.
