Yes, Bison does now parse the grammar file.
However, now I found another problem: the resulting C++ code does not
compile.
A very quick partial report (I've got to go now).
In LilyPond's parser.yy we have:
#define YYPARSE_PARAM my_lily_parser
#define YYLEX_PARAM my_lily_parser
extern My_lily_parser * current_parser;
int
yylex (YYSTYPE *s, void * v)
{
My_lily_parser *pars = (My_lily_parser*) v;
My_lily_lexer * lex = pars->lexer_;
lex->lexval = (void*) s;
lex->prepare_for_next_token();
return lex->yylex ();
}
Which works with bison <= 1.35, but doesn't with 1.50a. Has anything
changed wrt this? If it doesn't ring a bell, I'll investigate some
further tomorrow or on Monday.
Thanks.
Greetings,
Jan.
