Tracking locations error

[Kamel SEGHAIER]

Hi,

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 which is....

Can u help me.

Best regards.
Kamel
