android makefile



一、细节描述下面几步描述了如何配置makefile来为运行Android的设备编译系统。1、在//vendor/目录下创建company目录mkdir vendor/<company_name>2、在company目录下创建一个 products目录mkdir vendor/<company_name>/products/3、创建一个设备相关的makefile：vendor/<company_name>/products/<first_product_name>.mk这个make文件中至少要包含下面代码：$(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk)  #  # Overrides  PRODUCT_NAME := <first_product_name>  PRODUCT_DEVICE := <board_name>4、在产品定义文件中添加设备相关的变量。5、在products目录下，创建一个AndroidProducts.mk文件，这个文件指向设备的make文件。 #  # This file should set PRODUCT_MAKEFILES to a list of product makefiles  # to expose to the build system.  LOCAL_DIR will already be set to  # the directory containing this file.   #  # This file may not rely on the value of any variable other than  # LOCAL_DIR; do not use any conditionals, and do not look up the  # value of any variable that isn't set in this file or in a file that  # it includes.  #    PRODUCT_MAKEFILES := /    $(LOCAL_DIR)/first_product_name.mk /6、在company目录下创建一个包含特定board特征的目录，这个目录需要与PRODUCT_DEVICE这个变量中的<board_name>相匹配。这个目录下会包含一个make文件，这个make文件可以用下面的方式访问到，比如：mkdir vendor/<company_name>/<board_name>7、在上步的目录（vendor/<company_name>/<board_name>）下，创建一个BoardConfig.mk文件# These definitions override the defaults in config/config.make for <board_name>  #  # TARGET_NO_BOOTLOADER := false  #  TARGET_USE_GENERIC_AUDIO := true8、如果你想修改系统属性，在目录vendor/<company_name>/<board_name>下创建一个system.prop文件。# system.prop for   # This overrides settings in the products/generic/system.prop file  #  # rild.libpath=/system/lib/libreference-ril.so  # rild.libargs=-d /dev/ttyS09、在products/AndroidProducts.mk文件中添加一个指向<second_product_name>.mk的引用。PRODUCT_MAKEFILES := /    $(LOCAL_DIR)/first_product_name.mk /    $(LOCAL_DIR)/second_product_name.mk10、目录vendor/<company_name>/<board_name>下必须包含一个Android.mk文件，这个文件中至少包含下面的代码： # make file for new hardware  from   #  LOCAL_PATH := $(call my-dir)  #  # this is here to use the pre-built kernel  ifeq ($(TARGET_PREBUILT_KERNEL),)  TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel  endif  #  file := $(INSTALLED_KERNEL_TARGET)  ALL_PREBUILT += $(file)  $(file): $(TARGET_PREBUILT_KERNEL) | $(ACP)                $(transform-prebuilt-to-target)  #  # no boot loader, so we don't need any of that stuff..    #  LOCAL_PATH := vendor/<company_name>/<board_name>  #  include $(CLEAR_VARS)  #  # include more board specific stuff here? Such as Audio parameters.        #11、想为相同的board创建第二个product时，创建一个名字为vendor/company_name/products/<second_product_name>.mk的make文件，这个文件中包含：$(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk)  #  # Overrides  PRODUCT_NAME := <second_product_name>  PRODUCT_DEVICE := <board_name>目前为止，你已经有了两个新product，<first_product_name>和<second_product_name>，都属于<company_name>。验证一下一个product是否配置正确，运行  . build/envsetup.sh  make PRODUCT-<first_product_name>-user在/out/target/product/<board_name>目录下，你可以看到生成的二进制文件。二、产品文件树没有翻译三、product定义文件不同的产品，在它的product定义文件中会对一些变量赋予不同的值，product定义文件可以从其它product定义文件中继承。Product定义文件中包含的变量如下：

Parameter

Description

Example

PRODUCT_NAME

End-user-visible name for the overall product. Appears in the "About the phone" info.

 

PRODUCT_MODEL

End-user-visible name for the end product

 

PRODUCT_LOCALES

A space-separated list of two-letter language code, two-letter country code pairs that describe several settings for the user, such as the UI language and time, date and currency formatting. The first locale listed in PRODUCT_LOCALES is is used if the locale has never been set before.

地区标识

en_GB de_DE es_ES fr_CA

PRODUCT_PACKAGES

Lists the APKs to install.

在这个product中要安装的APK列表。

Calendar Contacts

PRODUCT_DEVICE

Name of the industrial design

生产商的名字

dream

PRODUCT_MANUFACTURER

Name of the manufacturer

制造商的名字

acme

PRODUCT_BRAND

The brand (e.g., carrier) the software is customized for, if any

软件定制后的分支标识。

 

PRODUCT_PROPERTY_OVERRIDES

List of property assignments in the format "key=value"

属性列表，以"key=value"形式列出。

 

PRODUCT_COPY_FILES

List of words like source_path:destination_path. The file at the source path should be copied to the destination path when building this product. The rules for the copy steps are defined in config/Makefile

当编译时，源路径上的文件会被复制到目标路径上去，具体的复制规则在config/Makefile中定义。

 

PRODUCT_OTA_PUBLIC_KEYS

List of OTA public keys for the product

 

PRODUCT_POLICY

Indicate which policy this product should use

 

PRODUCT_PACKAGE_OVERLAYS

Indicate whether to use default resources or add any product specific overlays

vendor/acme/overlay

PRODUCT_CONTRIBUTORS_FILE

HTML file containing the contributors to the project.

包含了项目贡献者名字列表的HTML文件。

 

PRODUCT_TAGS

下面给出了一个经典的product定义文件
$(call inherit-product, build/target/product/generic.mk)

#Overrides
PRODUCT_NAME := MyDevice
PRODUCT_MANUFACTURER := acme
PRODUCT_BRAND := acme_us
PRODUCT_LOCALES := en_GB es_ES fr_FR
PRODUCT_PACKAGE_OVERLAYS := vendor/acme/overlay
