Compilateur Yacc / Bison

Bonsoir a tous,
Je souhaite faire un petit compilateur pour requetes sql simples.

J'utilise Yack/Bison et Flex/lex, j'approche de la fin mais j'ai une serie d'erreurs identiques dans mon fichier .y lorsque je compile :

bison -d -v compil_sql.y -ocompil_sql.c
flex compil_sql.lex
gcc -Wall -c lex.yy.c
gcc -Wall -c compil_sql.c
compil_sql.c: In function «yyparse":

make: *** [compil_sql.o] Erreur 1

Voici une partie du code du fichier .y :
Code:

L'appel de la fonction cons_tree serv à créer l'arbre de requete.
N'ayant jamais rencontre ce type d'erreur j'aimerai en connaitre la cause (syntax, inclusion de headers, mauvaise edition de lien dans le makefile....).
Toute aide sera la bienvenue.

Merci par avance,

Cordialement.

Code:

$<ptr>2

Ça me parait bizarre, cette syntaxe...
Quand j'utilisais yacc en BTS, on disait $2 tout court, et on précisait le champ dans les déclarations %token...

Le problème vient effectivement de

Code:

$<ptr>2

.

Si je comprend bien, tu veux typer tes tokens. Dans ce cas ça se passe dans la directive %token.

En clair si tu veux que PROJECTION soit de type ptr alors il faut écrire

Code:

%token <ptr> PROJECTION

Sinon dans la partie règle il faut utiliser uniquement $1, $2, ...

Voilà.
