Hi Hans,
I'm using traking locations to detect error in my parser, i'm using
the macro YYLLOC_DEFAULT ,I define YYRHSLOC(Rhs, K) (Rhs)[K]) and
add the directive %locations and %pure_parser but i have always
this error :
`Rhs' undeclared (first use in this function).
May I miss some declaration but I don't know exactly ....
int yylex (YYSTYPE * lvalp, YYLTYPE * llocp );
#define YYRHSLOC(Rhs, K) (Rhs)[K])
#define YYLLOC_DEFAULT(Current, Rhs,
N) \
do \
if
(N) \
{ \
(Current).first_line = YYRHSLOC(Rhs,
1).first_line; \
(Current).first_column = YYRHSLOC(Rhs,
1).first_column; \
(Current).last_line = YYRHSLOC(Rhs,
N).last_line; \
(Current).last_column = YYRHSLOC(Rhs,
N).last_column; \
}
\
else \
{ \
(Current).first_line = (Current).last_line
= \
YYRHSLOC(Rhs,
0).last_line; \
(Current).first_column = (Current).last_column

YYRHSLOC(Rhs,
0).last_column; \
