'struct' member redefinition

**Fooshi** · 05/11/2010, 15h47

Hello,
j'ai une erreur a la compilation d'une extension php, un truc assez incomprehensible

Code :

/// session_open result declaration.
struct session_open_result
{
	net_sessid_t session_id;	///< The session_id choosen by the server, this session_id must be used for all subsequent calls to the server or they will fail.
};
 
/// session_reset result declaration.
struct session_reset_result
{
	net_sessid_t session_id;	///< The new session_id choosen by the server.
};

voici l'erreur :

error C2020: 'session_id' : 'struct' member redefinition

comme ci j'avais definie session_id dans la meme structure ce qui n'est pas le cas.
je vous donne mon code entier on sais jamais :

Je ne saurais pas trop te dire. Mais qu'est-ce que net_sessid_t ? Lorsque tu déclares un objet de type structure, il faut clairement indiquer struct, à moins que tu le crées comme un nouveau type (typedef).

Par exemple :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
struct machin
{
  int membre;
};
 
machin monobjet; /*ERREUR ! Le compilateur connait "struct machin" mais pas le type "machin". */

ne pourra pas compiler. Le compilateur ne connait pas machin mais seulement struct machin.

Mais si on écrit

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
typedef struct machin
{
  int membre;
} machin;
 
machin monobjet; /* OK ! Le compilateur connait le type "machin" */

là, ça compilera.

Peut-être que ton compilateur ne connait pas net_sessid_t mais seulement struct net_sessid_t ?

je comprendrais mon erreur si net_sessid_id etais un typedef d'une structure mais ici ce n'est pas le cas :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
 
typedef unsigned __int32 uint32_t;
typedef uint32_t net_sessid_t;

comme tu peux le voir c'est juste un entier non signé.

je viens d'essayer :

Code :

/// session_open result declaration.
typedef struct session_open_result
{
	net_sessid_t session_id;	///< The session_id choosen by the server, this session_id must be used for all subsequent calls to the server or they will fail.
}
session_open_result;
 
/// session_reset result declaration.
typedef struct session_reset_result
{
	net_sessid_t session_id;	///< The new session_id choosen by the server.
}
session_reset_result;

mais ce ne resous pas mon probleme. Lorsque je fais ca, ca me me met : "illegal storage class"

Bonjour
Ce serait pas

Code :

#ifndef ZTS  // au lieu de ifdef ZTS
#include "TSRM.h"
#endif

?

@pierre dolez : non ca c'est bon :-)

**jeroman** · 08/11/2010, 11h07

Difficile à dire avec aussi peu de code.

Bonjour,
Assurément, ce n'est pas vraiment le style que j'ai l'habitude d'utiliser, alors pardonnez-moi si je pose des questions idiotes.
Il y a pas mal de choses que je n'ai pas comprises, mais en voici une qui me parait pas très logique :

Code :

static const struct net_func session_reset_func_def =
{
    0,
    1,
    NULL,
    &session_reset_result_format
};

Vous initialisez une structure. Cette structure est static, donc, elle est initialisée au début, à l'ouverture. Or elle est aussi const donc, ne sera pas modifiée. Pourtant elle contient une référence, qui est probablement non-définie au moment de l'initialisation, et qui ne pourra de toute façon pas être modifiée.

@ Pierre Dolez:

Pourtant elle contient une référence, qui est probablement non-définie au moment de l'initialisation,

C'est l'adresse d'une structure static définie plus haut, donc il n'y a pas de problèmes. Sinon, d'ailleurs, le compilateur l'aurait signalé.

effectivement comme le dis diogene pas de probleme de ce coté la, et puis ca n'a pas de rapport avec mon probleme de départ. Je continue a chercher de mon coté mais je ne trouve vraiment pas

**Fooshi** · 09/11/2010, 10h26

Mon probleme est résolu !
en supprimant les macros ZEND_BEGIN_MODULE_GLOBALS(mod_0) et ZEND_END_MODULE_GLOBALS(mod_0) ca fonctionne (et puis je n'en ai pas l'utilité)

'struct' member redefinition
