    \node [block] (A) {A};
    \node [block,right of=A] (B) {B};
    \node [block,right of=B] (C) {loooooooooooooooong C};
    \node [block,right of=C] (D) {D};

Answer 1

Tienes que usar right = of(que es la sintaxis de positioningbiblioteca) en lugar de right of =.

    \node [block,right = of A] (B) {B};
    \node [block,right = of B] (C) {loooooooooooooooong C};
