El uso de una biblioteca dinámica (DevIL / OpenIL) en un proyecto de Xcode

Question

Estoy tratando de recopilar ejemplo el código fuente que está utilizando el OpenGL, SDL e IL aka aka DevIL bibliotecas OpenIL. OpenGL y SDL están disponibles como marcos nativos, pero diablo no es. Así que aquí es lo que hice:

He instalado DevIL a través de homebrew. En primer lugar he cambiado la fórmula, porque necesito Ilut:

brew edit devil

a continuación, editado estas líneas

def install
  system "./configure", "--disable-debug", "--disable-dependency-tracking",
                        "--prefix=#{prefix}", "--enable-ILU"
  system "make install"
end

así como

def install
  system "./configure", "--disable-debug", "--disable-dependency-tracking",
                        "--prefix=#{prefix}", "--enable-ILU", "--enable-ILUT"
  system "make install"
end

e instalado todo con

[sudo] brew install devil

lo que me da las cabeceras diablo en /usr/local/include/ y las bibliotecas dinámicas en /usr/local/lib/. A continuación, he añadido las bibliotecas de mi proyecto con los siguientes pasos:

• Haga clic en mi único objetivo
• Haga clic en "Añadir> marcos existentes"
• Seleccione "Dylibs"
• Agregar libIL.dylib, libILU.dylib y libILUT.dylib

(Hay también libIL.1.dylib, libILU.1.dylib y libILUT.1.dylib disponible en la lista, es eso normal?)

Luego añade las siguientes banderas en el "Proyecto> Editar Proyecto> Generar> Otras banderas conector":

-lil -lilu -lilut

Cuando intento compilar y vincular el proyecto me sale el siguiente error:

Al parecer, los archivos .dylib no están siendo construido correctamente y como resultado no se están encontrando los símbolos, pero ¿cómo puedo hacer este trabajo? ¿He cometido errores? ¿Hay una manera de construir las bibliotecas de manera diferente por lo que trabajar con mi proyecto, o puedo cambiar la arquitectura de construcción de mi proyecto de alguna manera?

Muchas gracias por su ayuda!

I solucionó el problema mediante la edición de la fórmula brew a:

def install
  system "./configure", "--disable-debug", "--disable-dependency-tracking",
                        "--prefix=#{prefix}", "--enable-ILU", "--enable-ILUT",
                        "CFLAGS=-arch i386", "CXXFLAGS=-arch i386"
  system "make install"
end
