Bibliothèque Complie Boost C++ pour appareils iOS fonctionnant sous armv7s

Question

J'ai réussi à construire une librairie boost C++ 1_44_0 pour iPhone/iPad sur armv6 et armv7 mais je n'arrive pas à créer une build pour les nouveaux périphériques fonctionnant sur armv7s.

Utilisé BoostOnIphone et le codage A sur Github pour créer des builds, tout ce dont j'ai besoin est Boost: Thread, Filesystem et System Library sur l'architecture armv7s.

Undefined symbols for architecture armv7s: 

Answer 1

Ma solution était de vérifier l'architecture de bibliothèque à l'aide du terminal:

otool -h libraryFile.a 

Sortie:

Mach header 
     magic cputype cpusubtype caps filetype ncmds sizeofcmds  flags 
0xfeedface  12   9 0x00   1  3  1588 0x00002000 

cputype et cpusubtype sont les valeurs de recherche :

pour ARMv7:

type cpu: 12 cpusubtype: 9

pour armv7s:

type cpu: 12 cpusubtype: 11

Maintenant, j'était dans une situation était il était impossible pour moi de mettre à jour l'architecture en tant que tierce partie. donc je fini par changer mon projet de construction Xcode:

• réglage Xcode (onglet bleu) Projet
• et l'architecture cible:
• l'architecture valide ajoutée seulement ARMv7
• build nettoyé et exécutez à nouveau

Une autre solution était d'utiliser Hacking an armv7s library en utilisant ce tutoriel. n'a pas fonctionné dans mon cas
