android编译系统的makefile文件Android.mk写法如下 (1)Android.mk文件首先需要指定LOCAL_PATH变量,用于查找源文件。由于一般情况下 Android.mk和需要编译的源文件在同一目录下,所以定义成如下形式: LOCAL_PATH:=$(call my-dir) 上面的语句的意思是将LOCAL_PATH变量定义成本文件所在目录路径。 (2)Android.mk中可以定义多个编译模块,每个编译模块都是以include $(CLEAR_VARS)开始 以include $(BUILD_XXX)结束。 include $(CLEAR_VARS) CLEAR_VARS由编译系统提供,指定让GNU MAKEFILE为你清除除LOCAL_PATH以外的所有LOCAL_XXX变量, 如LOCAL_MODULE,LOCAL_SRC_FILES,LOCAL_SHARED_LIBRARIES,LOCAL_STATIC_LIBRARIES等。 include $(BUILD_STATIC_LIBRARY)表示编译成静态库 include $(BUILD_SHARED_LIBRARY)表示编译成动态库。 include $(BUILD_EXECUTABLE)表示编译成可执行程序 (3)举例如下(frameworks/base/libs/audioflinger/Android.mk): LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS)  模块一 ifeq ($(AUDIO_POLICY_TEST),true)   ENABLE_AUDIO_DUMP := true endif LOCAL_SRC_FILES:= \     AudioHardwareGeneric.cpp \     AudioHardwareStub.cpp \     AudioHardwareInterface.cpp ifeq ($(ENABLE_AUDIO_DUMP),true)   LOCAL_SRC_FILES += AudioDumpInterface.cpp   LOCAL_CFLAGS += -DENABLE_AUDIO_DUMP endif LOCAL_SHARED_LIBRARIES := \     libcutils \     libutils \     libbinder \     libmedia \     libhardware_legacy ifeq ($(strip $(BOARD_USES_GENERIC_AUDIO)),true)   LOCAL_CFLAGS += -DGENERIC_AUDIO endif LOCAL_MODULE:= libaudiointerface ifeq ($(BOARD_HAVE_BLUETOOTH),true)   LOCAL_SRC_FILES += A2dpAudioInterface.cpp   LOCAL_SHARED_LIBRARIES += liba2dp   LOCAL_CFLAGS += -DWITH_BLUETOOTH -DWITH_A2DP   LOCAL_C_INCLUDES += $(call include-path-for, bluez) endif include $(BUILD_STATIC_LIBRARY)  模块一编译成静态库 include $(CLEAR_VARS)  模块二 LOCAL_SRC_FILES:=               \     AudioPolicyManagerBase.cpp LOCAL_SHARED_LIBRARIES := \     libcutils \     libutils \     libmedia ifeq ($(TARGET_SIMULATOR),true)  LOCAL_LDLIBS += -ldl else  LOCAL_SHARED_LIBRARIES += libdl endif LOCAL_MODULE:= libaudiopolicybase ifeq ($(BOARD_HAVE_BLUETOOTH),true)   LOCAL_CFLAGS += -DWITH_A2DP endif ifeq ($(AUDIO_POLICY_TEST),true)   LOCAL_CFLAGS += -DAUDIO_POLICY_TEST endif include $(BUILD_STATIC_LIBRARY) 模块二编译成静态库 include $(CLEAR_VARS) 模块三 LOCAL_SRC_FILES:=               \     AudioFlinger.cpp            \     AudioMixer.cpp.arm          \     AudioResampler.cpp.arm      \     AudioResamplerSinc.cpp.arm  \     AudioResamplerCubic.cpp.arm \     AudioPolicyService.cpp LOCAL_SHARED_LIBRARIES := \     libcutils \     libutils \     libbinder \     libmedia \     libhardware_legacy ifeq ($(strip $(BOARD_USES_GENERIC_AUDIO)),true)   LOCAL_STATIC_LIBRARIES += libaudiointerface libaudiopolicybase   LOCAL_CFLAGS += -DGENERIC_AUDIO else   LOCAL_SHARED_LIBRARIES += libaudio libaudiopolicy endif ifeq ($(TARGET_SIMULATOR),true)  LOCAL_LDLIBS += -ldl else  LOCAL_SHARED_LIBRARIES += libdl endif LOCAL_MODULE:= libaudioflinger ifeq ($(BOARD_HAVE_BLUETOOTH),true)   LOCAL_CFLAGS += -DWITH_BLUETOOTH -DWITH_A2DP   LOCAL_SHARED_LIBRARIES += liba2dp endif ifeq ($(AUDIO_POLICY_TEST),true)   LOCAL_CFLAGS += -DAUDIO_POLICY_TEST endif ifeq ($(TARGET_SIMULATOR),true)     ifeq ($(HOST_OS),linux)         LOCAL_LDLIBS += -lrt -lpthread     endif endif ifeq ($(BOARD_USE_LVMX),true)     LOCAL_CFLAGS += -DLVMX     LOCAL_C_INCLUDES += vendor/nxp     LOCAL_STATIC_LIBRARIES += liblifevibes     LOCAL_SHARED_LIBRARIES += liblvmxservice #    LOCAL_SHARED_LIBRARIES += liblvmxipc endif include $(BUILD_SHARED_LIBRARY) 模块三编译成动态库 (4)编译一个应用程序(APK)   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # Build all java files in the java subdirectory-->直译(建立在java子目录中的所有Java文件)   LOCAL_SRC_FILES := $(call all-subdir-java-files)       # Name of the APK to build-->直译(创建APK的名称)   LOCAL_PACKAGE_NAME := LocalPackage       # Tell it to build an APK-->直译(告诉它来建立一个APK)   include $(BUILD_PACKAGE) (5)编译一个依赖于静态Java库(static.jar)的应用程序   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # List of static libraries to include in the package   LOCAL_STATIC_JAVA_LIBRARIES := static-library       # Build all java files in the java subdirectory   LOCAL_SRC_FILES := $(call all-subdir-java-files)       # Name of the APK to build   LOCAL_PACKAGE_NAME := LocalPackage       # Tell it to build an APK   include $(BUILD_PACKAGE) (6)编译一个需要用平台的key签名的应用程序   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # Build all java files in the java subdirectory   LOCAL_SRC_FILES := $(call all-subdir-java-files)       # Name of the APK to build   LOCAL_PACKAGE_NAME := LocalPackage       LOCAL_CERTIFICATE := platform       # Tell it to build an APK   include $(BUILD_PACKAGE) (7)编译一个需要用特定key前面的应用程序   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # Build all java files in the java subdirectory   LOCAL_SRC_FILES := $(call all-subdir-java-files)       # Name of the APK to build   LOCAL_PACKAGE_NAME := LocalPackage       LOCAL_CERTIFICATE := vendor/example/certs/app       # Tell it to build an APK   include $(BUILD_PACKAGE) (8)添加一个预编译应用程序   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # Module name should match apk name to be installed.   LOCAL_MODULE := LocalModuleName   LOCAL_SRC_FILES := $(LOCAL_MODULE).apk   LOCAL_MODULE_CLASS := APPS   LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)       include $(BUILD_PREBUILT) (9)添加一个静态JAVA库   LOCAL_PATH := $(call my-dir)   include $(CLEAR_VARS)       # Build all java files in the java subdirectory   LOCAL_SRC_FILES := $(call all-subdir-java-files)       # Any libraries that this library depends on   LOCAL_JAVA_LIBRARIES := android.test.runner       # The name of the jar file to create   LOCAL_MODULE := sample       # Build a static jar file.   include $(BUILD_STATIC_JAVA_LIBRARY) (10)Android.mk的编译模块中间可以定义相关的编译内容,也就是指定相关的变量如下: LOCAL_AAPT_FLAGS LOCAL_ACP_UNAVAILABLE  LOCAL_ADDITIONAL_JAVA_DIR    LOCAL_AIDL_INCLUDES  LOCAL_ALLOW_UNDEFINED_SYMBOLS  LOCAL_ARM_MODE  LOCAL_ASFLAGS  LOCAL_ASSET_DIR  LOCAL_ASSET_FILES 在Android.mk文件中编译应用程序(BUILD_PACKAGE)时设置此变量,表示资源文件,                   通常会定义成LOCAL_ASSET_FILES += $(call find-subdir-assets)   LOCAL_BUILT_MODULE_STEM   LOCAL_C_INCLUDES 额外的C/C++编译头文件路径,用LOCAL_PATH表示本文件所在目录                  举例如下:                  LOCAL_C_INCLUDES += extlibs/zlib-1.2.3                  LOCAL_C_INCLUDES += $(LOCAL_PATH)/src    LOCAL_CC 指定C编译器 LOCAL_CERTIFICATE  签名认证 LOCAL_CFLAGS 为C/C++编译器定义额外的标志(如宏定义),举例:LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1   LOCAL_CLASSPATH  LOCAL_COMPRESS_MODULE_SYMBOLS  LOCAL_COPY_HEADERS install应用程序时需要复制的头文件,必须同时定义LOCAL_COPY_HEADERS_TO   LOCAL_COPY_HEADERS_TO install应用程序时复制头文件的目的路径 LOCAL_CPP_EXTENSION 如果你的C++文件不是以cpp为文件后缀,你可以通过LOCAL_CPP_EXTENSION指定C++文件后缀名                      如:LOCAL_CPP_EXTENSION := .cc                     注意统一模块中C++文件后缀必须保持一致。 LOCAL_CPPFLAGS 传递额外的标志给C++编译器,如:LOCAL_CPPFLAGS += -ffriend-injection LOCAL_CXX 指定C++编译器   LOCAL_DX_FLAGS LOCAL_EXPORT_PACKAGE_RESOURCES LOCAL_FORCE_STATIC_EXECUTABLE 如果编译的可执行程序要进行静态链接(执行时不依赖于任何动态库),则设置LOCAL_FORCE_STATIC_EXECUTABLE:=true                                目前只有libc有静态库形式,这个只有文件系统中/sbin目录下的应用程序会用到,这个目录下的应用程序在运行时通常                               文件系统的其它部分还没有加载,所以必须进行静态链接。   LOCAL_GENERATED_SOURCES   LOCAL_INSTRUMENTATION_FOR LOCAL_INSTRUMENTATION_FOR_PACKAGE_NAME LOCAL_INTERMEDIATE_SOURCES LOCAL_INTERMEDIATE_TARGETS LOCAL_IS_HOST_MODULE LOCAL_JAR_MANIFEST LOCAL_JARJAR_RULES LOCAL_JAVA_LIBRARIES 编译java应用程序和库的时候指定包含的java类库,目前有core和framework两种                      多数情况下定义成:LOCAL_JAVA_LIBRARIES := core framework                      注意LOCAL_JAVA_LIBRARIES不是必须的,而且编译APK时不允许定义(系统会自动添加)   LOCAL_JAVA_RESOURCE_DIRS  LOCAL_JAVA_RESOURCE_FILES  LOCAL_JNI_SHARED_LIBRARIES  LOCAL_LDFLAGS 传递额外的参数给连接器(务必注意参数的顺序)   LOCAL_LDLIBS 为可执行程序或者库的编译指定额外的库,指定库以"-lxxx"格式,举例:              LOCAL_LDLIBS += -lcurses -lpthread              LOCAL_LDLIBS += -Wl,-z,origin    LOCAL_MODULE 生成的模块的名称(注意应用程序名称用LOCAL_PACKAGE_NAME而不是LOCAL_MODULE) LOCAL_MODULE_PATH 生成模块的路径   LOCAL_MODULE_STEM    LOCAL_MODULE_TAGS 生成模块的标记    LOCAL_NO_DEFAULT_COMPILER_FLAGS  LOCAL_NO_EMMA_COMPILE  LOCAL_NO_EMMA_INSTRUMENT  LOCAL_NO_STANDARD_LIBRARIES  LOCAL_OVERRIDES_PACKAGES  LOCAL_PACKAGE_NAME APK应用程序的名称  LOCAL_POST_PROCESS_COMMAND   LOCAL_PREBUILT_EXECUTABLES 预编译including $(BUILD_PREBUILT)或者$(BUILD_HOST_PREBUILT)时所用,指定需要复制的可执行文件 LOCAL_PREBUILT_JAVA_LIBRARIES  LOCAL_PREBUILT_LIBS 预编译including $(BUILD_PREBUILT)或者$(BUILD_HOST_PREBUILT)时所用, 指定需要复制的库. LOCAL_PREBUILT_OBJ_FILES  LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES     LOCAL_PRELINK_MODULE 是否需要预连接处理(默认需要,用来做动态库优化) LOCAL_REQUIRED_MODULES 指定模块运行所依赖的模块(模块安装时将会同步安装它所依赖的模块)   LOCAL_RESOURCE_DIR LOCAL_SDK_VERSION LOCAL_SHARED_LIBRARIES 可链接动态库   LOCAL_SRC_FILES 编译源文件   LOCAL_STATIC_JAVA_LIBRARIES  LOCAL_STATIC_LIBRARIES 可链接静态库    LOCAL_UNINSTALLABLE_MODULE  LOCAL_UNSTRIPPED_PATH   LOCAL_WHOLE_STATIC_LIBRARIES 指定模块所需要载入的完整静态库(这些精通库在链接是不允许链接器删除其中无用的代码)   LOCAL_YACCFLAGS   OVERRIDE_BUILT_MODULE_PATH
