[RESOLVED] how should I arrange classes in files?

[Feoggou]

I do use #pragma once at the beginning of every header file.

I've changed my code in a few places. Now I've gotten to a situation like this:

file1.h:

namespace one
{
	class class1
	{
		int x;

		friend class class2;
	};
}

file2:

#include "file1.h"

class class2
{
public:
	int y;
	class class2()
	{
		one::class1 obj;
		obj.x = 3;
	}
};

main.cpp:

#include "file2.h"
....
//in the main function:
class2 obj;

And I get these errors in file2:

error C2248: 'one::class1::x' : cannot access private member declared in class 'one::class1'
IntelliSense: member "one::class1::x" (declared at line 6 of "d:\my projects\testslearn\testslearn\file1.h") is inaccessible

Why does the friendship not work? well... I assume it expects the class to belong in the same namespace. But, isn't there a way to do it without putting class2 in a namespace?

it seems that friend class ::class2; does not work, even if class2 is global.
It says:

error C2039: 'class2' : is not a member of '`global namespace''
error C2248: 'one::class1::x' : cannot access private member declared in class 'one::class1'
