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

============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=2.3.1
TARGET_PRODUCT=vm
TARGET_BUILD_VARIANT=eng
TARGET_SIMULATOR=false
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=x86
HOST_ARCH=x86

============================================

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:76: *
build/core/base_rules.mk:77: * Each module must use a LOCAL_MODULE_TAGS in its
build/core/base_rules.mk:78: * Android.mk. Possible tags declared by a module:
build/core/base_rules.mk:79: *
build/core/base_rules.mk:80: *     optional, debug, eng, tests, samples
build/core/base_rules.mk:81: *
build/core/base_rules.mk:82: * If the module is expected to be in all builds
build/core/base_rules.mk:83: * of a product, then it should use the
build/core/base_rules.mk:84: * “optional” tag:
build/core/base_rules.mk:85: *
build/core/base_rules.mk:86: *    Add “LOCAL_MODULE_TAGS := optional” in the
build/core/base_rules.mk:87: *    Android.mk for the affected module, and add
build/core/base_rules.mk:88: *    the LOCAL_MODULE value for that component
build/core/base_rules.mk:89: *    into the PRODUCT_PACKAGES section of product
build/core/base_rules.mk:90: *    makefile(s) where it’s necessary, if
build/core/base_rules.mk:91: *    appropriate.
build/core/base_rules.mk:92: *
build/core/base_rules.mk:93: * If the component should be in EVERY build of ALL
build/core/base_rules.mk:94: * products, then add its LOCAL_MODULE value to the
build/core/base_rules.mk:95: * PRODUCT_PACKAGES section of
build/core/base_rules.mk:96: * build/target/product/core.mk
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

###########################
# shared library for target

#LOCAL_MODULE := libdiskconfig
#LOCAL_MODULE_TAGS := system_builder
#LOCAL_SYSTEM_SHARED_LIBRARIES := libcutils liblog libc

#include $(BUILD_SHARED_LIBRARY)

将编译好的kernel拷贝到prebuilt下相应目录
carl@carl-amd64:/work/gb$ cp device/vm/vm/vm_defconfig prebuilt/android-x86/kernel/kernel_config_VirtualBox
carl@carl-amd64:/work/gb$ cp out/target/product/vm/kernel /work/gb/prebuilt/android-x86/kernel/kernel



开始全编译
carl@carl-amd64:/work/gb$ m -j3
