Android Studio利用cmakelists.txt编译OSG的方法总结

参考博文：

使用cmake依赖多个第三方库http://www.jianshu.com/p/5f29fd671750

OSG for Android教程  http://blog.csdn.net/dongzhong1990/article/details/51746758

错误汇总：

1、missing and no known rule to make it

解决方法：添加第三方库有误，第三方库名字可能笔误

2、OSG  cpp文件 undefined reference to XXX

解决方法：缺少添加OSG依赖的库，加上下面的设置

set(LOCAL_LDLIBS  "-llog -lGLESv1_CM -ldl -lz")

3、对第三方库的添加，只能一个个进行add_library,set_target_properties

步骤：

一、建立OSG窗口。在android项目中建立osg窗口的实质就是，通过render调用OSG，在GLSurfaceView上进行渲染。

二、打通JAVA和C之间的屏障。通过JNI来实现。JAVA层主要负责android的整体框架和组件的构建

三、OSG场景建立及渲染。与PC端开发OSG项目基本相同。

 

OSG for Android的demo源码很多，我也是从上面博文里抄过来的，关键难点在于对cmakelist.txt文件的编辑。网上很多少有对cmakelist的讲解，都是用android.mk实现的，所以尝试了很久，才完成对cmakelist的正确的编辑。在增加osg这个第三方静态库时，因为要增加40多个.a，有两种方法：一、add_library         set_target_properties。此方法要一个个增加，非常麻烦

注：第三方库文件名要输入全称。如libosg.a

二、link_directories(路径)   target_link_libraries(osgNativeLib  osgdb_dds ……)    比较简单

注：第三方库不需要输入全称。如osg

第一种方式编辑的cmakelists.txt如下：

cmake_minimum_required(VERSION 3.4.1)
set(libs_DIR ${CMAKE_SOURCE_DIR}/../../../../../../../01Lib)
set(LOCAL_ALLOW_UNDEFINED_SYMBOLS true)
set(LOCAL_LDLIBS  "-llog -lGLESv1_CM -ldl -lz")
