zeromq Build pour iOS avec libsodium, randombytes erreur

Question

Je construis zeromq bibliothèque pour iOS à l'aide de cette méthode: https://github.com/drewcrawford/libzmq-ios

Le journal de la construction semble bien sauf quelques avertissements qui apparaissent 3 fois:

Quand j'ajouter à mon bibliothèque rebâti projet XCode, il génère 10 erreurs:

ld: symbol(s) not found for architecture i386 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Je pense que toutes les fonctions, figurant dans l'e rrors, utilise randombytes, qui était listé dans warning.

La même chose arrive quand j'ajoute la bibliothèque de https://github.com/drewcrawford/libzmq-ios/releases

Ce que je fais mal?

Answer 1

On dirait que vous n'êtes pas il seul avec ce (ou similaire) numéro: https://github.com/drewcrawford/libzmq-ios/issues/4

À partir du lien: « Je suis en mesure de corriger ces erreurs par l'importation de la libC++ dylib dans mon projet. ». Leur problème était de répertorier l'architecture armv7 plutôt que, comme dans votre cas, l'architecture i386, mais c'est quelque chose à essayer.
