Problème définition multiple sur une lib externe

**RPGamer** · 16/03/2014, 22h44

Salut,

Je réalise le programme pour un petit robot équipé d'une carte RoBoard. La carte RoBoard peut être programmée avec la librairie RoBoIO rendant théoriquement les accès aux GPIO, port I2C, COM, SPI, etc. très faciles. C'est la première fois que je fais ça.

J'ai pris la version déjà compilée pour Linux depuis le site officiel du fabricant : http://www.roboard.com/download_ml.htm

Je développe avec Code::Blocks. J'ai donc ajouté les chemins Include/ et Lib/ dans Settings->Compiler...->Search directories et j'ai ajouté le fichier .a dans les options du projet via Project->Build options...->Linker settings.

Si je crée un programme en commençant avec un #include <roboard.h> comme indiqué dans les exemples, tout semble compiler correctement. Mon problème survient si plusieurs programmes incluent eux-mêmes roboard.h et que je les inclus dans un autre programme. Par exemple :

io.h

Si je tente de compiler, j'ai une série d'erreurs de type multiple definition of '' sur chaque fonction de la librairie.

Pourtant le code du fichier roboard.h dans le répertoire Include/ est le suivant :

Il me semble que les directives préprocesseur devraient empêcher toute inclusion multiple en cas d'utilisation de plusieurs programmes faisant appels à des fonctions de cette librairie.

Merci d'avance pour toute aide ou explication

Bonjour,

Pourrait-on avoir le contenu de la console de CB lors du build ?

J'ai donc ajouté les chemins Include/ et Lib/ dans Settings->Compiler...->Search directories et j'ai ajouté le fichier .a dans les options du projet via Project->Build options...->Linker settings

Tu aurais sans doute dû passé uniquement par les options du projet. Les include path et library path sont dans ton cas dépendant du projet. Pas bien grave.
Pourrais-tu nous faire un screenshot des linker settings du projet également ?

A priori, ce n'est pas un problème de garde d'inclusion sauf si du code est défini dans les fichiers h, ce qui normalement donne lieu à 20 coups de fouet en place publique.

Pour les options linker du projet :

C'est vrai pour les options du compilateur, du coup j'ai mis les chemins dans les options du projet uniquement.

Merci pour la réponse

Tu pourrais nous montrer le contenu de ce fichier aux alentours de la ligne 366 ?

La ligne 366 concerne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

    RB_INLINE RBAPI(void) rcservo_MoveToMix(unsigned long* width, unsigned long playtime, long* mixwidth) {

J'ai vérifié les directives #endif pour voir si il en manque mais ça m'aurait étonné de toute façon.

Le fichier commence par :

Code :

#ifndef __RCSERVO_H
#define __RCSERVO_H

et fini par :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#endif

de façon régulière pour que ce genre de cas n'apparaissent pas il me semble.

Dans les logs seuls 3 fichiers sur ceux inclus dans roboard.h semblent poser problème.

**Bktero** · 17/03/2014, 13h59

Cela me donne l'impression que le mot clé RBINLINE n'a pas été correctement transformé en static inline, mais peut-être en inline. Conséquence : les gardes d'inclusions marchent pour chaque unité de compilation mais si tu inclues le fichier dans 2 unités de compilation différentes, la fonction est définie 2 fois. As-tu inclus ce fichier h dans 2 fichiers c à toi ?

T'es tu intéressé à ces 2 macros ?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#if !defined(ROBOIO_DLL) || defined(__RCSERVO_LIB)

Sont-elles définies ou pas et pour quelles raisons ? Y a -il un fichier c de la lib qui contient aussi la définition de la fonction ?

**RPGamer** · 17/03/2014, 14h15

Il y a un fichier defines.h qui défini normalement la plupart de ces macros.

    #define _RB_INLINE  static
#endif

Pour ROBOIO_DLL, la définition est visiblement en commentaire, elle est probablement utilisée pour du code compilé pour Windows (j'ai téléchargé les binaires et le code source pour Linux). Et __RCSERVO_LIB est définie au début du fichier rcservo.c qui inclu le fichier rcservo.h.

As-tu inclus ce fichier h dans 2 fichiers c à toi ?

Je n'ai jamais inclu le fichier rcservo.h directement mais le fichier roboard.h de mon 2ème message est inclus dans plusieurs .c à moi oui.

Le corps de la fonctio rcservo_MoveToMix() n'est pas défini dans le fichier rcservo.c.

Edit :

J'ai remplacé ces lignes selon tes suppositions :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

2
#elif defined(__GNUC__)
    #define _RB_INLINE  __inline__

par

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
#elif defined(__GNUC__)
    #define _RB_INLINE  static __inline__

et ça à l'air de ne plus me poser problème !

Donc c'était effectivement ça merci

En revanche j'ai un autre souci mais qui cette fois est lié à l'architecture cible. Je compile sur un Core i7 (x64_86 je pense) pour le processeur de la RoBoard qui est un Vorted86DX (x86 donc). Du coup j'ai pris la version déjà compilée avec le .a pour x86 (si je compile moi-meme pour x86 ça ne change rien en fait). Pour compiler mon projet, j'ai rajouté l'option -m32 de GCC. J'obtiens la sortie suivante :

En faisant des recherches il y a quelques temps j'ai lu qu'il s'agissait d'un problème de division qui se faisait dans le mauvais mode (64 bits au lieu de 32 ou l'inverse je sais plus). J'ai lu aussi qu'il existe une fonction do_div() pour forcer une division sur 64 bits en incluant le fichier asm/div64.h. Mais je pense qu'il s'agit d'un tour de passe passe pour compiler sur une architecture 32 bits car le fichier asm/div64.h n'existe pas chez moi.

Voici la sortie des logs :

Une idée pour me mettre sur la voie ?
Merci encore ^.^

Edit 2 :

C'est bon j'ai trouvé, j'ai ajouté également l'option -m32 aussi dans les options du linker.
Merci.
