NDK Detailed system Parameters :

Local_path: = $ (call My-dir)

Specifies the Local_path variable, which is used to find the source file, meaning that the Local_path variable is defined as the directory path where the current file is located, and My-dir is a compiler-provided macro function that is used to obtain the current directory.

$ (call import-add-path,$ (Local_path)/. /.. /.. /.. /)

Import-add-path is used to add the path to the NDK_MODULE_PATH environment variable.

Include $ (clear_vars)

Clear_vars is provided by the build system, specifying that the GNU makefile for you to clear all local_xxx variables except Local_path, such as Local_module,local_src_files,local_shared_ Libraries and so on. Multiple compilation modules can be defined in a android.mk, with each compiled module starting with the include $ (clear_vars) and ending with the include $ (build_xxx).

Local_module: = cocos2dcpp_shared

Each android.mk file must define a module labeled Local_module, the name must be unique and does not contain any spaces, the compilation system will automatically modify the generated file prefix and suffix, If a module for the Foo Shared library will be changed to libfoo.so, if your module name is Libfoo, the compiled system generates a file for libfoo.so, and does not add the prefix, when you use the Android platform will automatically recognize

Local_module_filename: = Libcocos2dcpp

Local_module_filename specifying the module file name

Local_src_files: = hellocpp/main.cpp \

.. /.. /classes/appdelegate.cpp \

.. /.. /classes/helloworldscene.cpp

Local_src_files Specifies that the module is a C + + source file (. C. cpp. cc), separated by spaces between the files, and \ is a continuation character.

local_cpp_extension: = . cc. cpp

The default C + + file name extension is. cpp, local_cpp_extension can be used to specify different types of extensions, and do not forget the previous point

Local_c_includes + = $ (local_path)/. /.. /classes

Local_c_includes + = $ (local_path)/. /.. /classes/game

Local_c_includes + = $ (local_path)/. /.. /classes/lobby

The Local_c_includes parameter specifies the header file path that this module contains, separated by spaces between multiple paths

Local_whole_static_libraries + = Cocos2dx_static

Local_whole_static_libraries + = Cocosdenshion_static

The local_whole_static_libraries parameter is used to specify all the static library modules that are dependent on this module (connecting to a static connection library does not remove "Daed code", What is Dead code, which is a snippet and variable that the caller module will never use)

Local_static_libraries + = Cocos2dx_static

Local_static_libraries + = Cocosdenshion_static

The Local_ static_libraries parameter is used to specify all static library modules that are dependent on this module (when connecting to a static connection library, the "Daed code" is removed, which is what dead is, which is a snippet and variable that the caller module will never use)

include $ (build_static_library) represents the compilation into a static library.

include $ (build_shared_library) means to compile into a dynamic library ( i.e. shared library ) .

include $ (build_executable) represents a compilation into an executable program.

include $ (prebuilt_static_library) represents the definition of a precompiled static library module.

include $ (prebuilt_shared_library) represents the definition of a precompiled Dynamic library module.

$ (call import-module,cocos2dx) Import the External module (this indicates the import COCOS2DX Module , Cocos2dx is the module name Local_module , note that the command searches the path of the external module in the Ndk_module_path specified in or through $ (call import-add-path,$ (Local_path)/. /.. /) command import ).

Writing precompiled static libraries android.mk

Local_path: = $ (call My-dir)

Include $ (clear_vars)

Local_module: = libxml2_static

Local_src_files: = $ (Local_path)/lib/android/libxml2.a

Local_export_c_includes: = $ (Local_path)/include

Include $ (prebuilt_static_library)

Writing precompiled dynamic Libraries android.mk

Local_path: = $ (call My-dir)

Include $ (clear_vars)

Local_module: = Libyvimsdk

Local_src_files: = $ (Local_path)/libs/$ (Target_arch_abi)/libyvimsdk.so

Local_export_c_includes: = $ (Local_path)/include

Include $ (prebuilt_shared_library)
