Bonjour à tous,

j'ai beau chercher de tous les côtés, je ne trouve pas de solution.

Je suis sous Mac 10.6, je compile en C/C++ avec Xcode une application qui doit se connecter à Mysql.

J'ai donc telechargé les connector C et C++ sur le site de Mysql mais aucun d'eux ne marchent.

J'ai bien linké les librairies mais je me retrouve avec des erreurs du style :

ld: warning: in /Developer/External_libs/lib/libmysqlcppconn.dylib, file is not of required architecture
Undefined symbols:

J'ai essayé les connector C et C++,
l'include se fait bien car il trouve bien les fonctions au moment de la compilation mais pas au moment du linkage !!

Si vous avez une solution !!


Merci d'avance,

Julien.
