Compilación cruzada de bibliotecas basadas en Autotools para el iPhone SDK oficial

Question

Fondo

Estoy escribiendo un programa que se dirige a varios teléfonos diferentes, incluido el iPhone. El programa depende de varias bibliotecas de terceros. Estoy teniendo dificultades para compilar de forma cruzada estas bibliotecas de terceros para el simulador de iPhone y iPhone. Las bibliotecas incluyen Apache Portable Runtime y GNUTLS, así como sus dependencias. Me gustaría que las bibliotecas construidas terminen en los prefijos " /opt/iphone-3.1" ;, " /opt/iphone-3.0" ;, " /opt/iphone-2.2.1" ;, " / opt /iphone-simulator-3.1" ;, & " /opt/iphone-simulator-3.0" ;, respectivamente.

Para hacer que el proceso de compilación cruzada sea fácilmente repetible, estoy creando scripts para invocar " configurar " script para cada una de las plataformas de destino (" iphone3.1-configure " ;, " iphone3.0-configure " ;, " iphone2.2.1-configure " ;, " iphonesim3.1-configure " ;, y " iphonesim3.0 -configure "). Aquí es donde estoy teniendo problemas.

Estoy usando una computadora Mac OS X 10.6 Snow Leopard con el iPhone SDK 3.1 oficial de Xcode 3.2 +.

Estado

Actualmente tengo el siguiente " iphone3.1-configure " guión:

#! /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.

Pregunta

¿Cómo arreglo el " iphone3.1-configure " ¿guión? Gracias.

Answer 1

Ok. Esto todavía no se construye, pero llega mucho más lejos ...

  
1. El preprocesador de C no puede tomar una arquitectura.
  
2. El preprocesador de C no acepta --sysroot o -isystem (solo usa '-I').
  
3. Utilice " cpp " en lugar de " cpp-4.2 " (La versión 4.2 es defectuosa, y dado que es el preprocesador, no importa qué versión use, de todos modos, así que también puede usar la que funciona).

La versión actualizada del script de configuración de iphone3.1 es:

#! /bin/bash

También, estoy invocando con " - enable-threads --disable-dso " ;, no solo " - disable-dso " Esto todavía no funciona ... está fallando 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.

Sin embargo, esto puede ser un problema con las pruebas específicas de APR. Estoy publicando una pregunta de seguimiento en el enlace.

Answer 2

Gracias por tu guión. Me ayudó mucho. Aunque tuve que hacer algunos cambios para que la arquitectura de mi biblioteca construida sea arm y no i386 .

Primero, tuve que cambiar el compilador:

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

Luego eliminé la opción -arch armv6 , ya que este compilador no lo entiende, de CFLAGS, CXXFLAGS, LDFLAGS

Actualicé la versión de SDKVER y gcc y funcionó!
