Librerie basate su compilazione automatica di Autotools per iPhone SDK ufficiale

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

Domanda

Sfondo

Sto scrivendo un programma destinato a diversi telefoni, incluso l'iPhone. Il programma dipende da diverse librerie di terze parti. Sto incontrando difficoltà nella compilazione incrociata di queste librerie di terze parti per il simulatore iPhone e iPhone. Le librerie includono Apache Portable Runtime e GNUTLS, nonché le loro dipendenze. Vorrei che le librerie costruite finissero nei prefissi " /opt/iphone-3.1" ;, " /opt/iphone-3.0" ;, " /opt/iphone-2.2.1" ;, " / opt /iphone-simulator-3.1" ;, e " /opt/iphone-simulator-3.0" ;, rispettivamente.

Al fine di rendere facilmente ripetibile il processo di compilazione incrociata, sto creando degli script per invocare la "configurazione" script per ciascuna delle piattaforme di destinazione ("iphone3.1-configura", "iphone3.0-configura", "iphone2.2.1-configura", "iphoneim3.1-configura" e "iphoneim3.0 -configure "). È qui che ho problemi.

Sto usando un computer Mac OS X 10.6 Snow Leopard con Xcode 3.2 + iPhone SDK 3.1 ufficiale.

Stato

Al momento ho il seguente " iphone3.1-configure " 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.

Domanda

Come riparo " iphone3.1-configure " sceneggiatura? Grazie.

È stato utile?

Soluzione

Ok. Questo non si costruisce ancora, ma va molto oltre ...

      
  1. Il preprocessore C non può accettare un'architettura.
    2.   
  2. Il preprocessore C non accetta --sysroot o -isystem (basta usare '-I').
    3.   
  3. Usa " cpp " invece di "cpp-4.2" (la versione 4.2 è difettosa e, dato che è il preprocessore, non importa quale versione usi, comunque, quindi potresti anche usare quella che funziona.)

La versione aggiornata dello script di configurazione iphone3.1 è: 

#! /bin/bash

#
# Program  : iphone3.1-configure

# Synopsis :

Inoltre, sto invocando " - enable-thread --disable-dso " ;, non solo " - disable-dso " ;. Questo non funziona ancora ... non riesce con: 

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.

Tuttavia, questo potrebbe essere un problema con i test specifici di APR. Sto pubblicando una domanda di follow-up al link.

Modifica

Ho fornito una soluzione più completa in Compilazione incrociata di Apache Portable Runtime per iPhone .

Altri suggerimenti

Grazie per la tua sceneggiatura. Mi ha aiutato molto. Anche se ho dovuto apportare alcune modifiche in modo che l'architettura della mia libreria incorporata fosse arm e non i386 .

Innanzitutto, ho dovuto cambiare il compilatore: 

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

Quindi ho rimosso l'opzione -arch armv6 , poiché questo compilatore non lo capisce, da CFLAGS, CXXFLAGS, LDFLAGS

Aggiornata la versione di SDKVER e gcc e ha funzionato!
