Habilitación de herramientas inalámbricas en Android

1. Descargar wireless_tools.30.pre9.tar.gz . Esta versión admite caracteres no ASCII en el ESSID.

2. Desembálelo en mydroid/external/wireless-tools directorio.

3. Crear Android.mk con el siguiente contenido:

   LOCAL_PATH:= $(call my-dir)
   ################## build iwlib ###################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwlib.c
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= libiw
   LOCAL_STATIC_LIBRARIES := libcutils libc libm
   include $(BUILD_STATIC_LIBRARY)
   ################## build iwconfig #################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwconfig.c
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= iwconfig
   LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
   #LOCAL_FORCE_STATIC_EXECUTABLE := true
   LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
   #LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
   #LOCAL_MODULE_TAGS := eng user
   include $(BUILD_EXECUTABLE)
   ################## build iwlist ###################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwlist.c iwlib.h
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= iwlist
   LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
   #LOCAL_FORCE_STATIC_EXECUTABLE := true
   LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
   #LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
   #LOCAL_MODULE_TAGS := eng user
   include $(BUILD_EXECUTABLE)

4. Modifícalo como sigue:

   • Cambiar wireless.22.h para ser wireless.h ;
   • Modificar ifrename.c , añadir getline() función. Puede obtener el código de externo/genext2fs/genext2fs.c ; Observe que este archivo utiliza la macro para pasar otra función a getline() .
   • Modificar iwlib.h , cambie #include por #include . [Es posible que tenga que revisar el archivo original para saber a qué se refiere el autor]

5. Compilar

   ~/eclair-21/external/wireless-tools$ . ../../build/envsetup.sh
   ~/eclair-21/external/wireless-tools/wireless-tools$ mm

6. Copiar archivos en el sistema

   ~/eclair-21/external/wireless-tools$ croot
   ~/eclair-21$ cp out/target/product/generic/system/xbin/iwconfig /nfs/rootfs/system/xbin/iwconfig
   ~/eclair-21$ cp out/target/product/generic/system/xbin/iwlist /nfs/rootfs/system/xbin/

7. Prueba Después de iniciar Android:
