compilation problem

[logiq32]

Hi to all,

I need to compile a kind of program like this one:

class a;
class b;

class a { b b1;};
class b { a a1;};

int main(int argc, char *argv[]) { return 0; }

and i get this error message :
error: field 'b1' has incomplete type

is there some issue to get it working ?

Thank you.

class a { b* b1;};

ok, its better thank you, but now I'm stuck with a :

error: invalid use of incomplete type 'struct a'
error: forward declaration of 'struct a'

for this code:

class a;
class b;

class b
{
public:
    a *a1;
    b()
    {
        a1 = new a();
    }
};
class a
{
public:
    b *b1;
    a()
    {
        b1 = new b();
    }
};


void main(int argc, char *argv[])
{
    a my_a;
    b my_b;
}
