[20091221]编译Android操作系统(1)

（1）在android跟目录下执行(为何每次都要执行？)

. build/envsetup.sh

（2）建立自己的board

copy build/target/board/generic to build/target/board/idea6410

修改build/target/product/AndroidProduct.mk,添加

    $(LOCAL_DIR)/idea6410.mk \

copy build/target/product/generic.mk to build/target/product/idea6410.mk

修改

# Overrides

PRODUCT_BRAND := idea6410

PRODUCT_DEVICE := idea6410

PRODUCT_NAME := idea6410

（3）tapas

[kyon@SEP4020 android2.0]$ tapas

     2. userdebug

     3. eng

Which would you like? [eng] 

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

PLATFORM_VERSION_CODENAME=Eclair

以上只是基于generic简单的复制，需要更详细的定制开发板设备

附录：

1）build/target/product/idea6410.mk内容

# This is a generic product that isn't specialized for a specific device.

# It includes the base Android platform. If you need Google-specific features,

# you should derive from generic_with_google.mk

PRODUCT_PACKAGES := \

    AccountAndSyncSettings \

    AlarmClock \

    AlarmProvider \

    Bluetooth \

    Calculator \

    Calendar \

    Camera \

    CertInstaller \

    DrmProvider \

    Email \

    Gallery \

    LatinIME \

    Mms \

    Music \

    Settings \

    Sync \

    Updater \

    CalendarProvider \

    SyncProvider

$(call inherit-product, $(SRC_TARGET_DIR)/product/core.mk)

# Overrides

PRODUCT_BRAND := idea6410

PRODUCT_DEVICE := idea6410

PRODUCT_NAME := idea6410

产品名称及包含的应用程序

2）build/target/board/idea6410/BoardConfig.mk

# config.mk

#

# Product-specific compile-time definitions.

#

# The generic product target doesn't have any hardware-specific pieces.

TARGET_NO_BOOTLOADER := true

TARGET_NO_KERNEL := true

TARGET_CPU_ABI := armeabi

HAVE_HTC_AUDIO_DRIVER := true

BOARD_USES_GENERIC_AUDIO := true

不编译bootloader及内核

使用arm eabi编译器

使用HTC和通用音频（没有使用ALSA）

如果需要添加HAL层驱动，需要修改此文件

3）build/target/board/idea6410/AndroidBoard.mk

LOCAL_PATH := $(call my-dir)

file := $(TARGET_OUT_KEYLAYOUT)/tuttle2.kl

ALL_PREBUILT += $(file)

$(file) : $(LOCAL_PATH)/tuttle2.kl | $(ACP)

$(transform-prebuilt-to-target)

include $(CLEAR_VARS)

LOCAL_SRC_FILES := tuttle2.kcm

include $(BUILD_KEY_CHAR_MAP)

目前看来加入了一些键盘映射文件
