(二) Android.mk 引入系统库 引入第三方库 引入第三方头文件 引入静态库 写判断

如何引入系统库？

#LOCAL_SHARED_LIBRARIES  = libxxx  LOCAL_SHARED_LIBRARIES  = liblog

如何引入第三方库(动态库) xxx.so）

include $(CLEAR_VARS)  LOCAL_MODULE := test  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/main.cpp  LOCAL_SHARED_LIBRARIES  = liblog  #引入第三方库  LOCAL_LDFLAGS := -L./lib/ -ltest  #LOCAL_LDFLAGS := -L路径 -l库名  LOCAL_MODULE_PATH := $(LOCAL_PATH)/bin  include $(BUILD_EXECUTABLE)

如何引入第三方头文件？

#引入第三方头文件 LOCAL_C_INCLUDES := $(LOCAL_PATH)/inc

LOCAL_PATH:= $(call my-dir)  include $(CLEAR_VARS)  LOCAL_MODULE := libtest  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/test.cpp  LOCAL_MODULE_PATH_64 := $(LOCAL_PATH)/lib  include $(BUILD_SHARED_LIBRARY)   include $(CLEAR_VARS)  LOCAL_MODULE := test  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/main.cpp  LOCAL_SHARED_LIBRARIES  = liblog  #引入第三方头文件 LOCAL_C_INCLUDES := $(LOCAL_PATH)/inc  #引入第三方库 LOCAL_LDFLAGS := -L./lib/ -ltest  LOCAL_MODULE_PATH := $(LOCAL_PATH)/bin  include $(BUILD_EXECUTABLE)

直接在代码中引用绝对路径

#include<stdio.h> #include<utils/Log.h> #include<test.h>  #define LOG_TAG "main"  //extern void callMyDir(void);  int main(void) {     //test中的函数     callMyDir();     ALOGE("test");     return 0; }

如何引入静态库？ (xxx.a)

先编译一个静态库，然后放在里面lib路径下

#引入第三方静态库 LOCAL_LDFLAGS := $(LOCAL_PATH)/lib/libtest.a

LOCAL_PATH:= $(call my-dir)  include $(CLEAR_VARS)  LOCAL_MODULE := libtest  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/test.cpp  LOCAL_MODULE_PATH_64 := $(LOCAL_PATH)/lib  include $(BUILD_STATIC_LIBRARY)   include $(CLEAR_VARS)  LOCAL_MODULE := test  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/main.cpp  LOCAL_SHARED_LIBRARIES  = liblog  LOCAL_C_INCLUDES := $(LOCAL_PATH)/inc  #引入第三方静态库 LOCAL_LDFLAGS := $(LOCAL_PATH)/lib/libtest.a  LOCAL_MODULE_PATH := $(LOCAL_PATH)/bin  include $(BUILD_EXECUTABLE)

如何在mk判断写在文件中

LOCAL_PATH:= $(call my-dir)  include $(CLEAR_VARS)  LOCAL_MODULE := test  USED_SHARED := true  #LOCAL_C_ALL_FILES := $(call all-c-files-under)  LOCAL_SRC_FILES := src/main.cpp  LOCAL_SHARED_LIBRARIES  = liblog  LOCAL_C_INCLUDES := $(LOCAL_PATH)/inc  #判断 ifeq ($(USED_SHARED),true)  LOCAL_LDFLAGS := $(LOCAL_PATH)/lib/libtest.a  else  LOCAL_LDFLAGS := -L./lib/ -ltest  endif  LOCAL_MODULE_PATH := $(LOCAL_PATH)/bin  include $(BUILD_EXECUTABLE)
