Bullet(Cocos2dx)之交叉编译Android,集成到cocos2dx3.x

首先将src文件夹复制到jni文件夹，没有可以新建一个

新建两个文件Android.mk，Application.mk

Application.mk内容如下：

APP_ABI:=armeabiarmeabi-v7ax86

APP_PLATFORM:=android-8

APP_STL:=stlport_static

Android.mk内容如下：

LOCAL_PATH:=$(callmy-dir)

include$(CLEAR_VARS)

LOCAL_MODULE :=bullet_static(可随便起)

LOCAL_MODULE_FILENAME:=libbullet（可随便起）

LOCAL_C_INCLUDES:=src/(头文件位置)

（源文件，要列出所有用到的，这里用到BulletSoftBodyBulletDynamics

BulletCollisionsLinearMath）

最后还要加上一句，表示生成静态库如果将STATIC该文SHARED则生成动态库

include$(BUILD_STATIC_LIBRARY)

然后进入命令行

进入jni所在目录

ndk-build

等待编译完成

将三个目录下的libbullet.a分别复制到cocos2dx的安装目录下的

安装目录\Cocos\frameworks\cocos2d-x\prebuilt\android\相应文件下

进入Cocos\frameworks\cocos2d-x\external

新建文件夹Bullet，在Bullet下新建prebuild-mk

将Box2D\prebuild-mk下的Android.mk复制到Bullet/prebuild-mk

修改如下3行

LOCAL_MODULE:=bullet_static

LOCAL_MODULE_FILENAME:=libbullet

LOCAL_SRC_FILES:=../../../prebuilt/android/$(TARGET_ARCH_ABI)/libbullet.a

复制头文件

将bullet3的src的所有文件复制到新建的Bullet文件下

删除不是.h的所有文件

下一步任务繁重，

将所有用到BulletCollisionBulletDynamicsBulletSoftBodyLinearMath目录下的include都加上Bullet/,可以使用Notepad++在Bullet目录搜索Bullet,并替换为Bullet/Bullet，LinearMath并替换为Bullet/LinearMath

进入Cocos\frameworks\cocos2d-x\cocos\prebuilt-mk

在Android.mk

在LOCAL_WHOLE_STATIC_LIBRARIES+=box2d_static下面添加

LOCAL_WHOLE_STATIC_LIBRARIES+=bullet_static

$(callimport-module,Box2D/prebuilt-mk)下面添加

$(callimport-module,Bullet/prebuilt-mk)

至此已经完成编译静态库
