You're forgetting auxiliary routines (yyerror, yyprint, yydestruct
etc.).  Actually your work is almost to mimic what does, but
with member functions being functions.  The parser struct must
aggregate the parse-params, and provide it to the auxiliary functions.

As for yyparse, do not forget about the %initial-action either.
