Bibliothèques basées sur Autotools pour le SDK iPhone officiel

StackOverflow https://stackoverflow.com/questions/1602182

Question

Arrière-plan

Je suis en train d’écrire un programme qui cible plusieurs téléphones, y compris l’iPhone. Le programme dépend de plusieurs bibliothèques tierces. J'ai du mal à compiler ces bibliothèques tierces pour le simulateur iPhone et iPhone. Les bibliothèques incluent Apache Portable Runtime et GNUTLS, ainsi que leurs dépendances. Je voudrais que les bibliothèques construites se retrouvent avec les préfixes "/opt/iphone-3.1" ;," /opt/iphone-3.0" ;, "/opt/iphone-2.2.1" ;," / opt; /iphone-simulator-3.1" ;, et "/opt/iphone-simulator-3.0" ;, respectivement.

Afin de rendre le processus de compilation croisée facilement reproductible, je crée des scripts pour appeler la commande " configure " script pour chacune des plates-formes cibles ("iphone3.1-configure", "iphone3.0-configure", "iphone2.2.1-configure", "iphonesim3.1-configure", et "iphonesim3.0 -configure "). C’est là que j’ai des problèmes.

J'utilise un ordinateur Mac OS X 10.6 Snow Leopard avec le SDK officiel Xcode 3.2 + iPhone 3.1.

État

J'ai actuellement le " iphone3.1-configure " suivant; script: 

#! /bin/bash

#
# Program  : iphone3.1-configure
# Author   : Michael Aaron Safyan
# Synopsis :
#            This program runs the "configure" script generated by the
#            GNU Autotools in order to cross-compile thirdparty libraries
#            for the iPhone 3.1 SDK. Run this script while in a directory
#            containing an autotools "configure" script. Once run, this
#            you can use "make" and "sudo make install" to build the library.
#            An install prefix of "/opt/iphone-3.1/" is used.

Question

Comment puis-je réparer le " iphone3.1-configure " scénario? Merci.

Était-ce utile?

La solution

Ok. Cela ne construit toujours pas, mais ça va beaucoup plus loin ...

      
  1. Le préprocesseur C ne peut pas prendre une architecture.
    2.   
  2. Le préprocesseur C n'accepte pas --sysroot ou -isystem (utilisez simplement '-I').
    3.   
  3. Utilisez " cpp " au lieu de " cpp-4.2 " (la version 4.2 est défectueuse et, comme il s'agit du préprocesseur, peu importe la version que vous utilisez, vous pouvez également utiliser celle qui fonctionne.)

La version mise à jour du script iphone3.1-configure est la suivante: 

#! /bin/bash

#
# Program  : iphone3.1-configure

De plus, j'invoque avec "- enable-threads --disable-dso", pas seulement "- disable-dso". Cela ne fonctionne toujours pas ... il échoue avec: 

checking for PTHREAD_PROCESS_SHARED in pthread.h... yes
checking for pthread_mutexattr_setpshared... yes
checking for working PROCESS_SHARED locks... configure: error: in `/Users/michaelsafyan/Downloads/apr-1.3.8':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.

Toutefois, cela peut être un problème avec les tests spécifiques d’APR. Je poste une question de suivi sur le lien.

Modifier

J'ai fourni une solution plus complète à l'adresse Compilation croisée du moteur d'exécution Apache Portable pour iPhone .

Autres conseils

Merci pour votre script. Cela m'a beaucoup aidé. Bien que j'ai dû faire quelques modifications pour que l'architecture de ma bibliothèque construite soit arm et non i386 .

Tout d'abord, je devais changer le compilateur: 

# export CC="$DEVROOT/usr/bin/gcc-4.2"
export CC="$DEVROOT/usr/bin/arm-apple-darwin10-gcc-4.2.1"

Ensuite, j'ai supprimé l'option -arch armv6 , ce compilateur ne le comprenant pas, dans CFLAGS, CXXFLAGS, LDFLAGS

Mise à jour de la version SDKVER et gcc et tout a fonctionné!
