Symboles non trouvés erreur lors de la liaison de l'application iPhone dans Xcode

Question

Chaque fois que j'essaie de compiler mon application iPhone que je porte, je reçois des erreurs de liaison. L'application utilise un langage de script appelé Squirrel (pour lire les fichiers de niveau, très bien par le SDK, aucune entrée de l'utilisateur). J'ai lié toutes les bibliothèques, y compris libsquirrel.a. Qu'est-ce que je fais mal? (App est SuperTux, code source à supertux.lethargik.org pour la version d'ordinateur).

Quelque chose d'étrange peut-être aller avec libstdC++ - static.a. Je ne sais même pas ce que c'est.

Answer 1

C++ filt est votre ami il unmangle ces noms pour vous montrer ce qui manque:

> c++filt __ZN9Scripting24create_squirrel_instanceEP4SQVMPNS_12AmbientSoundEb 
Scripting::create_squirrel_instance(SQVM*, Scripting::AmbientSound*, bool) 

La première ligne de ci-dessus semble indiquer qu'il ne peut pas trouver la définition de la méthode create_squirrel_instace de la classe Scripting. Par conséquent, l'ordre dans lequel les bibliothèques sont présentées à g ++ (qui est le compilateur utilisé sur un mac) est important. Alors jetez un oeil à la sortie de la construction et de voir si vous pouvez trouver la ligne où les bibliothèques sont liées:

Il devrait ressembler à ceci:

g++ <STUFF> -l<lib1> -l<lib2> etc. 

Je reformatées la sortie de abovre il est lisible: dans le texte que je remplace

/Users/Thomas/Documents/iPhone Dev Projects./SuperTux avec <DIR> pour aider la lisibilité:

Un tas des bibliothèques ne sont pas utilisés becuase ils sont la mauvaise architecture:
