I get this error
error: field has incomplete type
when doing something like:
class MinhaClasse
{
MinhaClasse teste; // Erro aqui
};
I already tried to add this line at the beginning of the code class MinhaClasse; , but it did not work.
I understand the error, but I do not know how I can resolve it.
The error already says the problem. To set MinhaClasse need to set MinhaClasse , and enter loop infinite, there is no solution.
In fact there is a solution, it is to transform the field into a pointer, then it knows exactly how the field is composed since it is a pointer, something that the compiler already knows. That is, a indirection solves the problem. It may not be what you want, but it's the only way.
class MinhaClasse { MinhaClasse *teste; };
See running on ideone . And no Coding Ground . Also I placed GitHub for future reference .
or
class MinhaClasse { MinhaClasse unique_ptr<teste>; };
