Thread: C struct and a bit of yacc

I have the following code in yacc:

Code:

typedef struct data {
     int type;
     union {
        float f;
        char *str;
        int v;
     } d;
} data;

%}

%union
{ 
   data *typ;  ==> error occurs here in the y.tab.h
   char* stringcon;
   char charcon;
   char *id;
}

%type <typ> expr

however it gives me an error :

y.tab.h:24: error: expected specifier-qualifier-list before âdataâ

Can someone tell me why?

How about listening to and heeding to the words of your compiler. I see an error on line 22 that causes line 24 to become confused. Please just copy and paste code directly next time.

you have the same name for the typedef and the struct, thats name must be different.
example

Code:

  typedef struct strdata {...} data;
