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.

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 HOST_OS=linux HOST_BUILD_TYPE=release BUILD_ID=GINGERBREAD ============================================ 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.
