does not give a valid preprocessing token

Je compile des fichiers sous gcc 3.4.2 et jobtient la meme erreur a MAINTE reprise

Je comprend absolument rien du preprocessing token dont ils parlent??

Inliner la fonction reviendrait pas au même que la remplacer par cette macro tout en évitant ce genre de surprise?

Tu utilises une macro qui utilise ## de maniere abusive.

Hum lerreur devrait donc venir de mes PREC et SUIVANT

Code:

---

1 2 3

#define PREC(entite) mknom((entite),->prec) #define SUIVANT(entite) mknom((entite),->suivant)

---

Qui elle utilise mknom

Code:

---

1 2	#define mknom(a,b) a##b

---

Et la il aime pas mon ##....

Pourquoi PREC appelle mknom? mknom essaye de faire un symbole a partir de deux, ici tu lui en passe une floppee d'une part, et d'autre part tu passes des symboles qui ne peuvent pas faire un seul symbole s'ils sont juxtaposes.

Je ne suis pas lauteur du logiciel mais jimagine que cest pour obtenir comme resultat:


face->prec, dans le cas ou entite = face

Est-ce quil serait plus approprie de faire

Code:

---

#define PREC(entite) entite##->prec

---

?


EDIT: Memes erreurs :(

Mais pourquoi vouloir fusionner des symboles? Moi je ferais simplement:

Code:

---

#define PREC(entite) (entite)->prec

---

Woah javais pas penser a ca du tout

Merci beaucoup, je ten doit une!
