J'ai suivi le guide à Construire une bibliothèque statique lourde (dispositif + simulateur) à l'aide de Xcode et du SDK 4+. pour construire la libmms ( https://github.com/kosher-penguin/xcode-libmms ), et j'ai obtenu une grosse bibliothèque statique, mais cela ne semble pas fonctionner. J'ai des erreurs lorsque j'ajoute la bibliothèque à mon projet (xCode4.2+iOS5.0) :
Undefined symbols for architecture armv7:
"_iconv_close", referenced from:
_mms_connect in libMMS.a(mms.o)
"_Status_GetNewStatusByKey", referenced from:

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)Tout d'abord, je clone le code de https://github.com/kosher-penguin/xcode-libmms.git Deuxièmement, je l'ouvre avec xCode4.2, et j'ajoute la suite script à Run script(Build Phases), puis je lance le projet. Troisièmement, je copie le fichier nommé libmms.a dans le dossier nommé Release-universal, puis j'ajoute la bibliothèque à un nouveau projet. Quatrièmement, dans le nouveau projet, j'ajoute le fichier d'en-tête du projet xcode-libmms, j'importe mms.h et mms_config.h, et j'appelle la fonction mms_connect, puis je le construis, mais je reçois les erreurs.

mettre à jour : Après avoir ajouté la bibliothèque libiconv, l'erreur est la suivante :
