Reentrant Parser

[Ramaswamy]

Hi,

    I am using bison 1.75. I wanted to write a pure-parser where I pass a parameter to the yyparse. In the .y file I have given

 

---

"#define YYPARSE_PARAM   translationUnit"

---

 

and am using it in one of the productions. But I get the following msg -

---

./asnGrammar.y: In function `yyuserAction':
./asnGrammar.y:105: `translationUnit' undeclared (first use in this function)
./asnGrammar.y:105: (Each undeclared identifier is reported only once
./asnGrammar.y:105: for each function it appears in.)

---

 

    I have given %pure-parser declaration to enable pure parser generation. Only when I define the object in the yacc file itself in the same name 'translationUnit' does it work. But bison manual says that defining the macro is sufficient and the object can be from main file. Kindly advise as to how to pass arguement to a reentrant parser when the object is defined in some other fiile. Thanking you in advance.
