C++ defining static object inside class

I have a class A in "a.h":

#include "b.h"

class A {
public:
    static B b;
}

I want to initialize b in another function

In "main.cpp":

#include "a.h"
#include "b.h"

int main () {
    ....
    B A::b = B(arg1, arg2);

But the syntax checker give me the error: "member A::b cannot be defined in the current scope." What is the correct way of doing this?

You may set the value in main() but the definition has to be in the global scope:

#include "a.h"
#include "b.h"

B A::b; // <<<<<<

int main () {
    ....
    A::b = B(arg1, arg2);
 // ^^^^
