android編譯系統(tǒng)makefileAndroidmk寫法

1、android 編譯系統(tǒng)的 makefile 文件 Android.mk 寫法如下(l)Android.mk 文件首先需要指定 LOCAL_PATH 變量，用于查找源文件。由于一般情況下Android.mk 和需要編譯的源文件在同一目錄下，所以定義成如下形式：LOCAL_PATH:=$(callmy-dir)上面的語句的意思是將 LOCAL_PATH 變量定義成本文件所在目錄路徑。(2)Android.mk 中可以定義多個編譯模塊，每個編譯模塊都是以 include$(CLEAR_VARS)開始以 include$(BUILD_XXX)結束。include$(CLEAR_VARS)CLEAR_

2、VARS 由編譯系統(tǒng)提供，指定讓 GNUMAKEFILE 為你清除除 LOCAL_PATH 以外的所有 LOCAL_XXX 變量,如LOCAL_MODULE,LOCAL_SRC_FILES,LOCAL_SHARED_LIBRARIES,LOCAL_STATIC_LIBRARIES 等。include$(BUILD_STATIC_LIBRARY)表示編譯成靜態(tài)庫include$(BUILD_SHARED_LIBRARY)表示編譯成動態(tài)庫。include$(BUILD_EXECUTABLE)表示編譯成可執(zhí)行程序(3)舉例如下(frameworks/base/libs/audioflinger/An

16、nclude$(BUILD_STATIC_JAVA_LIBRARY)(10)Android.mk 的編譯模塊中間可以定義相關的編譯內(nèi)容，也就是指定相關的變量如下：LOCAL_AAPT_FLAGSLOCAL_ACP_UNAVAILABLELOCAL_ADDITIONAL_JAVA_DIRLOCAL_AIDL_INCLUDESLOCAL_ALLOW_UNDEFINED_SYMBOLSLOCAL_ARM_MODELOCAL_ASFLAGSLOCAL_ASSET_DIRLOCAL_ASSET_FILES 在 Android.mk 文件中編譯應用程序(BUILD_PACKAGE)時設置此變量，表示資源文

17、件,通常會定義成 LOCAL_ASSET_FILES+=$(callfind-subdir-assets)LOCAL_BUILT_MODULE_STEMLOCAL_C_INCLUDES 額外的 C/C+編譯頭文件路徑，用 LOCAL_PATH 表示本文件所在目錄舉例如下：LOCAL_C_INCLUDES+=extlibs/zlib-1.2.3LOCAL_C_INCLUDES+=$(LOCAL_PATH)/srcLOCAL_CC 指定 C 編譯器LOCAL_CERTIFICATE 簽名認證LOCAL_CFLAGS 為 C/C+編譯器定義額外的標志(如宏定義)，舉例：LOCAL_CFLAGS+=-

18、DLIBUTILS_NATIVE=1LOCAL_CLASSPATHLOCAL_COMPRESS_MODULE_SYMBOLSLOCAL_COPY_HEADERSinstall 應用程序時需要復制的頭文件，必須同時定義 LOCAL_COPY_HEADERS_TOLOCAL_COPY_HEADERS_TOinstall應用程序時復制頭文件的目的路徑LOCAL_CPP_EXTENSION 如果你的 C+文件不是以 cpp 為文件后綴，你可以通過 LOCAL_CPP_EXTENSION 指定 C+文件房綴名如：LOCAL_CPP_EXTENSION:=.cc 注意統(tǒng)一模塊中 C+文件后綴必須保持一致。

19、LOCAL_CPPFLAGS 傳遞額外的標志給 C+編譯器，如：LOCAL_CPPFLAGS+=-ffriend-injectionLOCAL_CXX 指定 C+編譯器LOCAL_DX_FLAGSLOCAL_EXPORT_PACKAGE_RESOURCESLOCAL_FORCE_STATIC_EXECUTABLE 如果編譯的可執(zhí)行程序要進行靜態(tài)鏈接（執(zhí)行時不依賴于任何動態(tài)庫），則設置 LOCAL_FORCE_STATIC_EXECUTABLE:=true目前只有 libc 有靜態(tài)庫形式，這個只有文件系統(tǒng)中/sbin 目錄下的應用程序會用到，這個目錄下的應用程序在運行時通常文件系統(tǒng)的其它部分還沒

21、AVA_LIBRARIES:=coreframework注意 LOCAL_JAVA_LIBRARIES 不是必須的，而且編譯 APK 時不允許定義（系統(tǒng)會自動添加）LOCAL_JAVA_RESOURCE_DIRSLOCAL_JAVA_RESOURCE_FILESLOCAL_JNI_SHARED_LIBRARIESLOCAL_LDFLAGS 傳遞額外的參數(shù)給連接器（務必注意參數(shù)的順序）LOCAL_LDLIBS 為可執(zhí)行程序或者庫的編譯指定額外的庫，指定庫以-lxxx格式，舉例：LOCAL_LDLIBS+=-lcurses-lpthreadLOCAL_LDLIBS+=-Wl,-z,originLOCAL_MODULE 生成的模塊的名稱(注意應用程序名稱用 LOCAL_PACKAGE_NAME 而不是 LOCAL_MODULE)LOCAL_MODULE_PATH 生成模塊的路徑LOCAL_MODULE_STEMLOCAL_MODULE_TAGS 生成模塊的標記LOCAL_NO_DEFAULT_COMPILER_FLAGSLOCAL_NO_EMMA_COMPILELOCAL_NO_EMMA_INSTRUMENTLOCAL_NO_STANDARD_LIBRARIESLOCAL_OVERRIDES_PACKAGE
