Android.mk 参数函数查询


查询地址：http://android.cloudchou.com/build/core/base_rules.php#LOCAL_INSTALLED_MODULE

build/core/base_rules.mk

base_rules.mk里定义了生成某种目标的方式

目标类型：主机上的可执行程序，设备上的可执行程序，apk程序，Java运行库，动态链接库等等

Android编译系统里每一种目标的生成方式对应一个makefile，

示例：如果某个模块需要编译成手机上的二进制程序，它需要include $(BUILD_EXECUTABLE)

而BUILD_EXECUTABLE指向的是$(BUILD_SYSTEM)/executable.mk

所有生成方式对应的makefile都将包含base_rules.mk

LOCAL_PATH

每个模块都在Android.mk里定义，表示模块所在目录

LOCAL_MODULE

LOCAL_MODULE表示模块的名称

LOCAL_MODULE将在每个模块的makefile里定义，如果未定义，编译系统会报错

LOCAL_IS_HOST_MODULE

表示该模块生成的目标是否在主机上运行，

my_prefix

若定义了 LOCAL_IS_HOST_MODULE 为true，那么my_prefix:=HOST_，否则 my_prefix:=TARGET_

my_host

若定义了 LOCAL_IS_HOST_MODULE 为true，那么 my_host:=host-，否则 my_host:=

LOCAL_UNINSTALLABLE_MODULE

表示该模块是否安装至手机，像sdk文档模块不会被安装至手机，因此LOCAL_UNINSTALLABLE_MODULE为true

LOCAL_MODULE_TAGS

模块的tag，为debug eng tests optional samples shell_ash shell_mksh等tag的组合，一个模块可有多个Tag,

注意现在模块现在不能使用user作为模块的Tag,

以前如果使用user做为tag,那么这个模块将被自动安装，

如果想定义自动安装的模块，需要在PRODUCT_PACKAGES变量里添加该模块，

该变量在build/target/product/base.mk和build/target/product/core.mk里有赋值，这是所有产品都将继承的基础配置

另外每个设备可在自己的产品配置文件device_*.mk里设置该变量，添加更多的模块

如果当前目录或者父目录有*_GPL*的文件，那么将自动添加gnu的tag

LOCAL_MODULE_CLASS

将用于决定编译时的中间文件存放的位置

LOCAL_MODULE_CLASS在定义目标生成方式的makefile文件里定义，

比如executable.mk里定义LOCAL_MODULE_CLASS := EXECUTABLES

在recovery模块的Android.mk里定义的LOCAL_MODULE_CLASS有：

LOCAL_MODULE_CLASS := RECOVERY_EXECUTABLES

LOCAL_MODULE_CLASS := UTILITY_EXECUTABLES

其它的LOCAL_MODULE_CLASS有

LOCAL_MODULE_CLASS := ETC

LOCAL_MODULE_CLASS := STATIC_LIBRARIES

LOCAL_MODULE_CLASS := EXECUTABLES

LOCAL_MODULE_CLASS := FAKE

LOCAL_MODULE_CLASS := J***A_LIBRARIES

LOCAL_MODULE_CLASS := SHARED_LIBRARIES

LOCAL_MODULE_CLASS := APPS

对应 Cyanogenmod/target/product/m7ul/obj 的目录

比如说若 LOCAL_MODULE_CLASS := ETC

那么该模块编译的中间文件将存放于

Cyanogenmod/target/product/m7ul/obj/ETC

partition_tag

如果是主机模块，partition_tag将为空，否则如果是设备专有模块，partition_tag:=_VENDOR

否则如果是安装到系统的模块，那么partition_tag将为空(test模块生成的目标只安装至data目录)

否则partition_tag:=_DATA

LOCAL_PROPRIETARY_MODULE

是否是设备专有模块

LOCAL_MODULE_PATH

表示模块生成的目标将最终存放的目录

recovery模块的Android.mk里有

LOCAL_MODULE := nandroid-md5.sh

LOCAL_MODULE_PATH := $(TARGET_RECOVERY_ROOT_OUT)/sbin

说明：nandroid-md5.sh 将存放于out/Cyanogenmod/target/product/m7ul/recovery/root/sbin

如果模块的Android.mk里未定义LOCAL_MODULE_PATH

那么LOCAL_MODULE_PATH := $($(my_prefix)OUT$(partition_tag)_$(LOCAL_MODULE_CLASS))

在recovery模块里recovery可执行文件相关变量如下：

比如my_prefix为TARGET_，partition_tag为空,LOCAL_MODULE_CLASS为EXECUTABLES

那么LOCAL_MODULE_PATH为$(TARGET_OUT_EXECUTABLES)，

值应该为

out/Cyanogenmod/target/product/m7ul/system/bin

module_id

用于确保每个模块都是唯一的

module_id := MODULE.$(if \

$(LOCAL_IS_HOST_MODULE),HOST,TARGET).$(LOCAL_MODULE_CLASS).$(LOCAL_MODULE)

如果$(module_id)已经定义过，那会提示用户出错

recovery模块的Android.mk里针对recovery可执行文件：

module_id := MODULE.TARGET.EXECUTABLES.RECOVERY

$(MODULE.TARGET.EXECUTABLES.RECOVERY)=$(LOCAL_PATH)

即当前模块路径

intermediates

intermediates := $(call local-intermediates-dir)

例： recovery模块Android.mk里编译Recovery可执行文件：

out/target/product/find5/obj/EXECUTABLES/recovery_intermediates

intermediates.COMMON

intermediates.COMMON := $(call local-intermediates-dir,COMMON)

例： recovery模块Android.mk里编译Recovery可执行文件：

out/target/common/obj/EXECUTABLES/recovery_intermediates

LOCAL_MODULE_STEM

表示编译链接后的目标文件的文件名，不带后缀

LOCAL_MODULE_STEM := $(strip $(LOCAL_MODULE_STEM))

ifeq ($(LOCAL_MODULE_STEM),)

LOCAL_MODULE_STEM := $(LOCAL_MODULE)

endif

例：

recovery模块编译recovery可执行文件：

LOCAL_MODULE_STEM:=recovery

LOCAL_MODULE_SUFFIX

表示编译链接后的目标文件的后缀

LOCAL_INSTALLED_MODULE_STEM

表示要安装的目标文件的文件名，带后缀

LOCAL_INSTALLED_MODULE_STEM := $(LOCAL_MODULE_STEM)$(LOCAL_MODULE_SUFFIX)

例：

recovery模块编译recovery可执行文件：

LOCAL_INSTALLED_MODULE_STEM:=recovery

LOCAL_BUILT_MODULE_STEM

表示编译链接后的目标文件的文件名，带后缀

LOCAL_BUILT_MODULE_STEM := $(strip $(LOCAL_BUILT_MODULE_STEM))

ifeq ($(LOCAL_BUILT_MODULE_STEM),)

LOCAL_BUILT_MODULE_STEM := $(LOCAL_INSTALLED_MODULE_STEM)

endif

例：

recovery模块编译recovery可执行文件：

LOCAL_INSTALLED_MODULE_STEM:=recovery

OVERRIDE_BUILT_MODULE_PATH

只有内部动态链接库模块可以使用OVERRIDE_BUILT_MODULE_PATH

OVERRIDE_BUILT_MODULE_PATH := $(strip $(OVERRIDE_BUILT_MODULE_PATH))

ifdef OVERRIDE_BUILT_MODULE_PATH

ifneq ($(LOCAL_MODULE_CLASS),SHARED_LIBRARIES)

$(error $(LOCAL_PATH): Illegal use of OVERRIDE_BUILT_MODULE_PATH)

endif

built_module_path := $(OVERRIDE_BUILT_MODULE_PATH)

else

built_module_path := $(intermediates)

endif

built_module_path

参见OVERRIDE_BUILT_MODULE_PATH

LOCAL_BUILT_MODULE

表示编译链接后的目标文件(文件路径+文件名)

LOCAL_BUILT_MODULE := $(built_module_path)/$(LOCAL_BUILT_MODULE_STEM)

比如recovery:

LOCAL_BUILT_MODULE 路径；

out/Cyanogenmod/target/product/m7ul/obj/EXECUTABLES/recovery_intermediates/recovery

LOCAL_INSTALLED_MODULE

表示模块的安装路径+文件名

ifneq (true,$(LOCAL_UNINSTALLABLE_MODULE))

LOCAL_INSTALLED_MODULE := $(LOCAL_MODULE_PATH)/$(LOCAL_INSTALLED_MODULE_STEM)

endif

示例：

out/Cyanogenmod/target/product/m7ul/system/bin/recovery

LOCAL_INTERMEDIATE_TARGETS += $(proto_java_sources_file_stamp)

aidl_sources

表示所有源代码中的aidl文件

aidl_sources := $(filter %.aidl,$(LOCAL_SRC_FILES))

如果想编译aidl，只需将aidl加入LOCAL_SRC_FILES即可，

frameworks/base/Android.mk里有将aidl文件加入LOCAL_SRC_FILES变量

LOCAL_SRC_FILES += \

core/java/android/accessibilityservice/IAccessibilityServiceConnection.aidl \

core/java/android/accessibilityservice/IAccessibilityServiceClient.aidl \

core/java/android/accounts/IAccountManager.aidl \

core/java/android/accounts/IAccountManagerResponse.aidl \

core/java/android/accounts/IAccountAuthenticator.aidl \

如果没有定义 TARGET_BUILD_APPS 变量，说明要编译framework.jar，那么将

编译系统还为每一个模块还定义了其它两个变量

ALL_MODULES.$(LOCAL_MODULE).BUILT 所有模块的生成路径

ALL_MODULES.$(LOCAL_MODULE).INSTALLED 所有模块的各自安装路径

例如：手机中将安装在system/bin/recovery，那么ALL_MODULES.recovery.INSTALLED为out/target/product/find5/system/bin/recovery

每个模块都会定义该模块生成的目标类型，可能生成二进制文件，也可能生成java静态库

这是由这个模块include $(BUILD_)决定的

比如build type若是EXCECUTABLE，，那么将include $(BUILD_EXECUTABLE)，那么将include build/core/executable.mk

而该makefile对应生成的目标类型是在手机上的可执行程序

executable.mk里包含了binary.mk，而binary.mk包含了base_rules.mk

ifeq ($(strip $(LOCAL_MODULE_PATH)),)

$(error $(LOCAL_PATH): unhandled LOCAL_MODULE_CLASS "$(LOCAL_MODULE_CLASS)")

endif

endif

LOCAL_MODULE_PATH:表示要安装的位置，可由编译系统推算，也可由某个模块显示指定

# $(3): if non-empty, this is a HOST target.

# $(4): if non-empty, force the intermediates to be COMMON 如果是host的common，则是out/host/common，如果是target的common，则是out/target/common

使用举例：

./development/build/Android.mk framework_res_package := $(call intermediates-dir-for,APPS,framework-res,,COMMON)/package-export.apk

./frameworks/base/core/res/Android.mk:37:framework_GENERATED_SOURCE_DIR := $(call intermediates-dir-for,J***A_LIBRARIES,framework,,COMMON)/src

值： out/target/product/find5/obj/STATIC_LIBRARIES/libstdc++_intermediates

Function: copy-file-to-target

The -t option to acp and the -p option to cp is

required for OSX. OSX has a ridiculous restriction

where it's an error for a .a file's modification time

to disagree with an internal timestamp, and this

macro is used to install .a files (among other things).

Copy a single file from one place to another,

preserving permissions and overwriting any existing

file.

We disable the "-t" option for acp cannot handle

high resolution timestamp correctly on file systems like ext4.

Therefore copy-file-to-target is the same as copy-file-to-new-target.

Function: copy-file-to-target-with-cp
