Android 2.3 GingerBread for VirtualBox x86编译指南

时间有限，格式未调整，见谅。

谢谢原作者。

 

 

展开源码,用AOSP的bionic目录替换(gingerbread)的bionic

删除bootable/diskinstaller，拷贝froyo-x86的newinstaller到bootable目录下；拷贝gingerbread的bootable/diskinstaller/libdiskconfig目录到bootable/newinstaller目录下

修改build/core/Makefile，注释掉bootable/diskinstaller/config.mk的引用

链接froyo-x86的kernel；cd /work/gb; ln -sf /work/x86/kernel/ .

将x86/build/core/kernel.mk拷贝过来，并include在build/core/Makefile中

 

$(INSTALLED_BOOTIMAGE_TARGET): $(MKBOOTIMG) $(INTERNAL_BOOTIMAGE_FILES)

        $(call pretty,"Target boot image: $@")

        $(hide) $(MKBOOTIMG) $(INTERNAL_BOOTIMAGE_ARGS) --output $@

        $(hide) $(call assert-max-image-size,$@,$(BOARD_BOOTIMAGE_PARTITION_SIZE),raw)

endif # TARGET_BOOTIMAGE_USE_EXT2

 

include $(BUILD_SYSTEM)/kernel.mk

 

else    # TARGET_NO_KERNEL

# HACK: The top-level targets depend on the bootimage.  Not all targets

# can produce a bootimage, though, and emulator targets need the ramdisk

# instead.  Fake it out by calling the ramdisk the bootimage.

# TODO: make the emulator use bootimages, and make mkbootimg accept

#       kernel-less inputs.

INSTALLED_BOOTIMAGE_TARGET := $(INSTALLED_RAMDISK_TARGET)

endif

 

将froyo_x86的device/vm拷贝到device目录下，在AndroidBoard.mk中注释掉TARGET_PREBUILT_APPS

将build/core/target/board/generic_x86下面的buildspec*拷贝到根目录的buildspec.mk并修改BUILD_ENV_SEQUENCE_NUMBER为10

编译环境设置（每次编译前不要忘记lunch vm-eng以防止编译错误目标）

carl@carl-amd64:/work/gb$ . build/envsetup.sh 

including device/htc/passion/vendorsetup.sh

including device/samsung/crespo/vendorsetup.sh

including device/vm/vm/vendorsetup.sh

carl@carl-amd64:/work/gb$ lunch vm-eng

将下面两行加入build/target/product/generic_x86.mk末尾

GENERIC_X86_CONFIG_MK := $(SRC_TARGET_DIR)/board/generic_x86/BoardConfig.mk

GENERIC_X86_ANDROID_MK := $(SRC_TARGET_DIR)/board/generic_x86/AndroidBoard.mk

 

开始编译内核

carl@carl-amd64:/work/gb$ m -j3 kernel

 

 

消除LOCAL_MODULE_TAGS的问题(external/grub)，设置LOCAL_MODULE_TAGS := optional

build/core/base_rules.mk:74: *** Module name: grub_stage1

build/core/base_rules.mk:75: *** Makefile location: external/grub

build/core/base_rules.mk:86: *    Add "LOCAL_MODULE_TAGS := optional" in the

build/core/base_rules.mk:97: * 

build/core/base_rules.mk:98: *** user tag detected on new module - user tags are only supported on legacy modules.  Stop.

make: Leaving directory `/work/gb'

 

去掉多余的libdiskconfig目标

build/core/base_rules.mk:158: *** bootable/newinstaller/libdiskconfig: MODULE.TARGET.SHARED_LIBRARIES.libdiskconfig already defined by system/core/libdiskconfig.  Stop.

注释掉bootable/newinstaller/libdiskconfig/Android.mk中libdiskconfig相关代码

将编译好的kernel拷贝到prebuilt下相应目录

__dso_handle的问题解决

collect2: ld returned 1 exit status

 

修改external/stlport/dll_main.cpp加入

extern "C" {

void * __dso_handle = 0;

}

 

dnsmasq的dbus引用问题解决

 

external/dnsmasq/src/dbus.c:21:23: error: dbus/dbus.h: No such file or directory

external/dnsmasq/src/dbus.c:100: error: expected ')' before '*' token

external/dnsmasq/src/dbus.c:261: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'message_handler'

 

修改external/dnsmasq/src/config.h

/* #define HAVE_DBUS */

#ifdef __ANDROID__

#undef HAVE_DBUS

#endif

 

 

libnfc-nxp的问题解决

target arm C: libnfc <= external/libnfc-nxp/src/phLibNfc.c

cc1: error: unrecognized command line option "-mapcs"

cc1: error: unrecognized command line option "-mno-sched-prolog"

cc1: error: unrecognized command line option "-mabi=aapcs-linux"

cc1: error: unrecognized command line option "-mno-thumb-interwork"

 

修改external/libnfc-nxp/Android.mk将

LOCAL_CFLAGS += -DNXP_MESSAGING -DINCLUDE_DALINIT_DEINIT -pipe -fomit-frame-pointer -Wall -Wno-trigraphs -Werror-implicit-function-declaration  -fno-strict-aliasing -mapcs -mno-sched-prolog -mabi=aapcs-linux -mno-thumb-interwork -msoft-float -Uarm -fno-common –fpic

改为

LOCAL_CFLAGS += -DNXP_MESSAGING -DINCLUDE_DALINIT_DEINIT -pipe -fomit-frame-pointer -Wall -Wno-trigraphs -Werror-implicit-function-declaration  -fno-strict-aliasing -msoft-float -Uarm -fno-common -fpic

 

in mkuserimg.sh PATH=out/host/linux-x86/bin/:/boot/jdk/bin:/home/carl/bin:/opt/android/tools:/opt/android/platform-tools:/opt/depot_tools:/boot/jdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/work/gb/out/host/linux-x86/bin:/work/gb/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:/work/gb/development/emulator/qtools:/work/gb/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:/work/gb/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin

Only ext4 is supported!

修改各个image的文件系统支持

直接修改build/target/board/generic_x86/BoardConfig.mk

 

TARGET_USERIMAGES_USE_EXT4 := true

TARGET_BOOTIMAGE_USE_EXT2 := true

TARGET_SYSTEMIMAGES_USE_EXT2 := true

 

修改build/core/Makefile

 

ifeq ($(INTERNAL_USERIMAGES_USE_EXT),true)

 ## generate an ext2 image

 # $(1): output file

 define build-systemimage-target

     @echo "Target system fs image: $(1)"

     $(call build-userimage-ext-target, $(TARGET_OUT), $(1), system, $(INTERNAL_USERIMAGES_EXT_VARIANT), $(BOARD_SYSTEMIMAGE_PARTITION_SIZE))

 endef

改为

ifeq ($(INTERNAL_USERIMAGES_USE_EXT),true)

  ifeq ($(TARGET_SYSTEMIMAGES_USE_EXT2),true)

    -include external/genext2fs/Config.mk

    ## generate an ext2 image

    # $(1): output file

    define build-systemimage-target

      @echo "Target system fs image: $(1)"

      $(call build-userimage-ext2-target,$(TARGET_OUT),$(1),system,)

    endef

    else

    define build-systemimage-target

      @echo "Target system fs image: $(1)"

      $(call build-userimage-ext-target,$(TARGET_OUT),$(1),system,$(INTERNAL_USERIMAGES_EXT_VARIANT),$(BOARD_SYSTEMIMAGE_PARTITION_SIZE))

    endef

  endif

 

完成后，可以直接

carl@carl-amd64:/work/gb$ export USE_SQUASHFS=0

carl@carl-amd64:/work/gb$ m -j3 iso_img

 

 

IAudioEffect.c的问题解决

out/target/product/vm/obj/SHARED_LIBRARIES/libOpenSLES_intermediates/IAndroidEffect.o:(.data.rel.ro._ZTIN7android12SortedVectorINS_16key_value_pair_tImPNS_11AudioEffectEEEEE[typeinfo for android::SortedVector<android::key_value_pair_t<unsigned long, android::AudioEffect*> >]+0x0): undefined reference to `vtable for __cxxabiv1::__vmi_class_type_info'

out/target/product/vm/obj/SHARED_LIBRARIES/libOpenSLES_intermediates/IAndroidEffect.o:(.data.rel.ro._ZTIN7android12SortedVectorINS_16key_value_pair_tImPNS_11AudioEffectEEEEE[typeinfo for android::SortedVector<android::key_value_pair_t<unsigned long, android::AudioEffect*> >]+0x10): undefined reference to `typeinfo for android::SortedVectorImpl'

collect2: ld returned 1 exit status

将system/media/opensles/libopensles/IAndroidEffect.c换名IAndroidEffect.cpp并更新Android.mk文件

 

init.rc不执行拷贝的问题

在build/target/board/generic_x86/AndroidBoard.mk中指定的init.rc模块，无论如何设置都不会执行拷贝，这是由于新版本的build system脚本调整导致的麻烦，需要强制在definitions.mk中指定安装init.rc模块。

ifeq ($(TARGET_PROVIDES_INIT_RC), true)

ALL_DEFAULT_INSTALLED_MODULES:=init.rc

else

ALL_DEFAULT_INSTALLED_MODULES:=

endif

 

SQUASHFS生成目标的支持问题

froyo-x86默认是生成SQUASHFS，如下修改bootable/newinstaller/Android.mk为默认不生成SQUASHFS；如果需要设置生成SQUASHFS，只需要在make前export USE_SQUASHFS=1

 

# use squashfs for iso, unless explictly disabled

ifeq ($(USE_SQUASHFS),1)

MKSQUASHFS = $(shell which mksquashfs)

 

在Makefile中集成system.sfs目标

 

$(INSTALLED_SYSTEMIMAGE): $(BUILT_SYSTEMIMAGE) $(RECOVERY_FROM_BOOT_PATCH) | $(ACP)

        @echo "Install system fs image: $@"

        $(copy-file-to-target)

        $(hide) $(call assert-max-image-size,$@ $(RECOVERY_FROM_BOOT_PATCH),$(BOARD_SYSTEMIMAGE_PARTITION_SIZE),yaffs)

 

ifneq ($(MKSQUASHFS),)

$(PRODUCT_OUT)/system.sfs: $(BUILT_SYSTEMIMAGE)

        $(call build-squashfs-target,$^,$@)

endif

 

systemimage: $(INSTALLED_SYSTEMIMAGE)

 

 

init.rc的定制问题

 

Gingerbread修改了system/core/init模块的代码，init.rc的支持也变得更加强大。

init.rc需要根据不同平台来进行定制，否则在chroot到android后会出现严重问题。

基本思路是基于Android原生的init.rc修改，添加文件系统mount的指令，添加eth0启动时支持。

 

 

BOARD_KERNEL_CMDLINE的问题

由于没有使用diskinstaller，所以build/target/board/generic-x86/BoardConfig.mk中KERNEL_CMDLINE如下修改

# For VirtualBox and likely other emulators

#BOARD_INSTALLER_CMDLINE := init=/init console=ttyS0 console=tty0 androidboot.hardware=generic_x86 vga=788 verbose

#BOARD_KERNEL_CMDLINE := init=/init console=tty0 console=ttyS0 androidboot.hardware=generic_x86 vga=788

BOARD_KERNEL_CMDLINE := init=/init console=tty0 androidboot.hardware=$(TARGET_PRODUCT) acpi_sleep=s3_bios,s3_mode vga=788
