salut mes amis
quand j'utulise le map de sdl cad je fais #include <map>
using namespace std ;

je trouver plusieurs warning
je sais q'il ya une commande qui elimine les warning
c'est #pragma ..... disabled
ya qq qui le connais

[Médinoc]

1. Je ne vois pas ce que vient faire "sdl" là-dedans.
2. Et si tu nous montrait plutôt tes warnings ?
   De plus, le pragma ne marche que sous Visual...

[killer_instinct]

voila ce que j'ai dans #include "stdfx.h"

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#include <map>
#include <string>
#include "iostream.h"
using namespace std


beh le probleme que cette map fais bcp des warning
j'utulise vc++ version 6.0

[killer_instinct]

voila un examplaire des warnings

1. Plus de iostream.h. Le header standard, c'est <iostream>
2. Jamais de using namespace dans un header. Jamais. Je parie que c'est ça qui génère le plus de bordel.

Quant au warning, en effet, on peut virer ça. Sans doute un bug de Visual 6, donc on peut le désactiver ainsi:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#pragma warning(disable:4786)

[koala01]

Salut,

En plus, bien plus que d'essayer d'éviter l'affichage des warnings, il serait intéressant, apres avoir pris en compte les remarques de medinoc , de plutot essayer de prendre en compte celles qui restent pour voir si tu ne peut pas les corriger...

En effet, un warning en lui meme ne fait rien ("Attention, vous faites quelques choses de suspect")... Mais ca peut attirer ton attention sur quelque chose qui est susceptible de provoquer un comportement indéfini...

Et qui dit "comportement indéfini" dit "risque de plantage" aléatoire, quand, par malheur, on essaye de faire le genre de chose qu'on n'essaye qu'une fois tous les trois ans

Un simple exemple, le fameux et souvent rencontré "warning: comparison between signed and unsigned integer expressions" qui ne posera aucun problème tant que tu resteras dans la fourchette des nombres non signés... mais qui pourrait en poser quand tu passera du coté des nombres négatifs

[Volune]

Quand on lit le warning :

identifier was truncated to '255' characters in the debug information

On se rend compte que ça vient du compilateur, et que ça n'a rien de vraiment grave sur l'exécution du programme.
Soit tu désactive le warning, soit tu passe en "Release", soit tu change de compilo ^^
