error de compilación para simulador de iphone

Question

Estoy intentando compilar un código para el simulador de iPhone, pero recibo este error:

    /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -O3 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk -Os  -O3 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk -Os -x objective-c -I../../include  -c version.c      
    In file included from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/Security.h:29,

                     from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:80,
                     from version.c:11:

    make: *** [version.o] Error 1

Sin embargo, si compilo para el iPhone real, funciona bien:

    /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -O3 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk  -arch armv6  -Os  -O3 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk  -arch armv6  -Os -x objective-c -I../../include  -c version.c      

Este problema ocurre con un archivo tan simple como incluir Foundation.h sin otro código:

#import <Foundation/Foundation.h>

¿Alguna idea sobre de qué se trata? Lo extraño es que esperaría que esto fallara tanto para el iphone como para el simulador.

EDITAR: para su información, no estoy usando XCode. Este es un gran proyecto multiplataforma que utiliza Makefiles. Los comandos que ve arriba fueron emitidos desde el Makefile.

Answer 1

Vi lo mismo. La solución es agregar una directiva del compilador -miphoneos-version-min = 3.0.

Answer 2

El problema solo ocurre si usa SDK 3.0 con el simulador de iphone. Usando SDK 2.0 (con gcc 4.0) se compilará. Esto parece ser lo que XCode usa por defecto.

Es muy extraño que este problema sea solo para el simulador y no para el iPhone en sí. También es extraño que gcc4.2 no se compile con el simulador sdk 2.0: debe usar gcc4.0.

Para los curiosos, escribí un archivo MAKE que demuestra el problema:

IPHONE_GCC_VER    = 4.0
IPHONE_SDK_VER    = 3.0
IPHONE_DEV_PATH   = /Developer/Platforms/iPhoneOS.platform/Developer
IPHONE_SDK        = $(IPHONE_DEV_PATH)/SDKs/iPhoneOS$(IPHONE_SDK_VER).sdk 
IPHONE_GCC        = $(IPHONE_DEV_PATH)/usr/bin/gcc-$(IPHONE_GCC_VER)

SIMULATOR_GCC_VER = 4.0
SIMULATOR_SDK_VER = 2.0
SIMULATOR_DEV_PATH= /Developer/Platforms/iPhoneSimulator.platform/Developer
SIMULATOR_SDK     = $(SIMULATOR_DEV_PATH)/SDKs/iPhoneSimulator$(SIMULATOR_SDK_VER).sdk
SIMULATOR_GCC     = $(SIMULATOR_DEV_PATH)/usr/bin/gcc-$(SIMULATOR_GCC_VER)

TEST_FILE=/tmp/test.m

all: info make-test-file
    $(IPHONE_GCC)    -isysroot $(IPHONE_SDK)    -arch armv6 -c $(TEST_FILE) 
    $(SIMULATOR_GCC) -isysroot $(SIMULATOR_SDK) -arch i386  -c $(TEST_FILE) 

info:
    @echo "iphone gcc   : $(IPHONE_GCC_VER)"
    @echo "iphone sdk   : $(IPHONE_SDK_VER)"
    @echo "simulator gcc: $(SIMULATOR_GCC_VER)"
    @echo "simulator sdk: $(SIMULATOR_SDK_VER)"
    @echo ""

make-test-file:
    echo "#import <Foundation/Foundation.h>" > $(TEST_FILE)

Los valores predeterminados son los que funcionan, pero puede anularlos en la línea de comandos. Por ejemplo:

$ make -f Makefile.iphone-error-demo SIMULATOR_SDK_VER=3.0 SIMULATOR_GCC_VER=4.0
iphone gcc   : 4.0
iphone sdk   : 3.0
simulator gcc: 4.0
simulator sdk: 3.0

Answer 3

¿Está seguro de que su configuración es idéntica entre los dos proyectos? Apuesto a que accidentalmente cambiaste algunas configuraciones del simulador.

Answer 4

Haga clic derecho en el marco y haga clic en Obtener información. Eche un vistazo a la ruta en el cuadro de diálogo Información. Debería ser breve, como " Sistema / Biblioteca / Frameworks / "

Si no es así, use el botón Elegir para buscar el marco debajo de la carpeta del SDK actual.

Además, asegúrese de que, justo debajo de la ruta, vea la opción "Relativo al SDK actual". seleccionado.

Answer 5

Cuando agregó los marcos a su proyecto, ¿estableció la casilla de verificación en SÍ cuando se le preguntó si deseaba copiar el marco en la carpeta del proyecto? Si es así, la casilla de verificación debe establecerse en NO.

¿Esto también sucede si crea un nuevo proyecto e intenta ejecutarlo sin agregar nada, porque es posible que haya cambiado accidentalmente los indicadores de compilación en ese proyecto

Answer 6

Esto debe solucionarse agregando esto a las opciones del compilador:

-D__IPHONE_OS_VERSION_MIN_REQUIRED=30000

Answer 7

Encontré este problema al cambiar un proyecto de SDK 3.2 a 4.1. Resulta que la solución estaba cambiando el Objetivo de implementación de iOS en la configuración de compilación de mi proyecto de 2.0 a 3.0 .

Haga clic derecho en su proyecto en xcode (si lo está usando), panel de compilación, Objetivo de implementación de iOS - > 3.0.
