ios - auth - Duplicar símbolos al integrar SDK de Firebase y Google Sign In manualmente sin Cocoapods

google sign in swift

Question

Recibo un error con símbolos duplicados al integrar SDK de Firebase y Google Sign In manualmente en mi proyecto iOS existente.

La pregunta SO relacionada aquí no ayudó ya que usa Cocoapods.

Firebase y Google Signin dan error de símbolos duplicados

Pasos que he tomado en orden cronológico:

1. Carpeta Copied Analytics, Auth and Database junto con el archivo Firebase.h del Firebase SDK descargado (3.11.0) en mi proyecto y agregado a los objetivos.

2. Copió GoogleService-Info.plist en el proyecto y se agregó a los objetivos.

3. Se agregó el indicador -ObjC a otros indicadores del enlazador.

4. Copié los marcos y los paquetes necesarios del SDK de inicio de sesión de Google (4.0.1) descargado en mi proyecto y los agregué a los objetivos.

5. Vincula los marcos y bibliotecas necesarios.

Aquí está la estructura del proyecto relacionado:

Firebase
    Analytics
        FirebaseAnalytics.framework
        FirebaseCore.framework
        FirebaseInstanceId.framework
        GoogleInterchangeUtilities.framework
        GoogleSymbolUtilities.framework
        GoogleToolboxForMac.framework
    Auth
        FirebaseAuth.framework
        GTMSessionFetcher.framework
GoogleSignIn
    GoogleAppUtilities.framework
    GoogleSignIn.bundle
    GoogleSignIn.framework
    GoogleSignInDependencies.framework
    GoogleSymbolUtilities.framework (removed as Firebase Analytics already includes it)

ld: 194 duplicate symbols for architecture x86_64

Answer 1

La verdadera pregunta es; ¿Por qué está copiando directamente en lugar de usar cocoapods? Realmente no hay ventaja al usar tu método. Si usas cocoapods, no tendrás este problema. Si yo fuera tú, eliminaría estos archivos e instalaría con cocoapods. Hay mucho menos margen de error cuando instala cocoapods

Answer 2

Así es como lo resolví, aunque está lejos de ser la solución ideal.

(Esta solución se puede aplicar a cualquier caso en el que dos bibliotecas estáticas provoquen un error de "símbolo duplicado" debido a que ambas bibliotecas contienen clases comunes y usan -ObjC o -all_load flag.)

Copie el archivo GoogleSignInDependencies dentro de GoogleSignInDependencies.framework en una RUTA de ubicación separada. Este archivo es un archivo grueso que significa que tiene códigos para diferentes arquitecturas.

Abra la terminal y vaya a RUTA.

$ cd PATH

Ejecute el comando siguiente comando para obtener información sobre la biblioteca de grasa.

$ lipo -info GoogleSignInDependencies

Obtendrás el siguiente resultado.

Architectures in the fat file: GoogleSignInDependencies are: armv7 i386 x86_64 arm64

Como puede ver, hay 4 arquitecturas en el archivo gordo.

Obtenga los archivos delgados (archivo que contiene código para una sola arquitectura) del archivo gordo ejecutando los siguientes comandos.

$ lipo -thin armv7 GoogleSignInDependencies -output armv7.a
$ lipo -thin i386 GoogleSignInDependencies -output i386.a
$ lipo -thin x86_64 GoogleSignInDependencies -output x86_64.a
$ lipo -thin arm64 GoogleSignInDependencies -output arm64.a

Obtendrás 4 archivos delgados llamados armv7.a, i386.a, x86_64.a y arm64.a.

Elimina el archivo GoogleSignInDependencies, ya no lo necesitamos.

Crea 4 nuevas carpetas llamadas armv7, i386, x86_64 y arm64. A continuación, mueva los archivos finos armv7.a, i386.a, x86_64.a y arm64.a a las carpetas respectivas. Debería tener una estructura de carpetas como la siguiente.

arm64
    arm64.a
armv7
    armv7.a
i386
    i386.a
x86_64
    x86_64.a

Vaya a cada una de las 4 carpetas del terminal y extraiga los archivos del objeto (* .o) de los archivos delgados con los siguientes comandos.

$ cd armv7
$ ar -x armv7.a
$ cd ../i386
$ ar -x i386.a
$ cd ../x86_64
$ ar -x x86_64.a
$ cd ../arm64
$ ar -x arm64.a

Después de ejecutar estos comandos, cada una de las 4 carpetas debe contener los siguientes archivos. (Esto puede cambiar en versiones futuras).

__.SYMDEF
GTMGeometryUtils_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMLogger_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMNSDictionary+URLArguments_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMNSString+URLArguments_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMOAuth2Authentication_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMOAuth2SignIn_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMOAuth2ViewControllerTouch_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcher_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcherLogging_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcherService_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionUploadFetcher_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSynchronizationAsserts_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o

Elimine los archivos que entran en conflicto con la biblioteca de Firebase desde cada una de las 4 carpetas. Debes eliminar estos 6 archivos. (Esto puede cambiar en versiones futuras).

GTMLogger_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMNSDictionary+URLArguments_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcher_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcherLogging_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionFetcherService_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o
GTMSessionUploadFetcher_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.o

Elimine los archivos delgados armv7.a, i386.a, x86_64.a y arm64.a.

Combine los archivos de objetos restantes en archivos finos ejecutando los siguientes comandos.

$ cd armv7
$ libtool -static *.o -o armv7-new.a
$ cd ../i386
$ libtool -static *.o -o i386-new.a
$ cd ../x86_64
$ libtool -static *.o -o x86_64-new.a
$ cd ../arm64
$ libtool -static *.o -o arm64-new.a

Copie los archivos delgados recién creados armv7-new.a, i386-new.a, x86_64-new.a y arm64-new.a en una nueva ubicación PATH_NEW. Puedes eliminar todo lo demás dentro de PATH.

Combine los nuevos archivos delgados en un nuevo archivo gordo ejecutando los siguientes comandos.

$ cd PATH_NEW
$ lipo -create armv7-new.a i386-new.a x86_64-new.a arm64-new.a -output GoogleSignInDependencies-new

Utilice GoogleSignInDependencies-new recién generado en lugar de GoogleSignInDependencies en su proyecto de Xcode.

Answer 3

Si tienes este problema, acabo de escribir un script bash shell que hace todo el trabajo por mí. Lo he guardado como un Gist . Úselo bajo su propio riesgo.
