$ 1 z `… 'nemá v Bison / Yacc žiaden deklarovaný typ - linux, kompilátor, yacc, bizón

Keď vykonám príkaz yacc -dv c2p.y na mojom súbore yacc c2p.y, chyba $ 1 "..." nemá deklarovaný typ v Bison / Yacc sa vyskytne niekoľkokrát.

Viem, že musím pridať niečo typu% a vymazať reťazec $ 1.string, ale stále to nefunguje.

Môžete mi pomôcť vyriešiť túto chybu?

Tu je môj počiatočný kód:
