OSG&OSGEarth编译心得

编译OSG

1. 下载数据源
   http://www.openscenegraph.org/downloads/stable_releases/
   
2. 下载最全的（含full）第三方库
   https://download.osgvisual.org/
   
3. 官网下载源码
   http://www.openscenegraph.org/index.php/download-section/stable-releases
   
4. 下载cmake-gui
   https://cmake.org/
5. 新建OSG文件夹，将下载好的资源解压在OSG文件夹中。
   
   新建INSTALL文件夹，用于编译成功后导出需要的include、lib、data，将三方库放在OSG文件夹下。
6. 使用cmake生成vs解决方案（根据需要进行选择）
   
   点击Configue，进行相关配置。
   
   
   
   

我是按照如上配置进行的，再点击Configue

这个不管了。下面的我也未处理。

Configuring done

点击Generate，很快会提示Generating done。
7. 选择对应版本的VS打开项目，进行编译。
选择OpenSceneGraph解决方案，右键选择“批生成”

选择ALL_BUILD的Release（可以根据需要选择），点击生成。编译需要3个小时左右，编译完成后，取消ALL_BUILD的Release的选择，重新选择INSTALL的Release，点击生成，这个快。

生成完成之后，在INSTALL的文件下就会出现include、bin、lib等文件夹。

编译OSGEarth

1.在F盘新建文件件，OSG3.4.0，将3rdarty和编译好的OSG全部放在这个文件夹下，将data也放在该文件夹下。

2.配置环境变量

OSG_FILE_PATH：F:\OSG3.4.0\data
PATH：F:\OSG3.4.0\bin;F:\OSG3.4.0\share\OpenSceneGraph\bin

3.将CMakeLists.txt拖入，Cmake中，点击Configue

4.检查全部三方配置，有的都配置好，记得配置INSTALL。

把LINKER后面的内容去掉。再次点击Configue

Could NOT find Protobuf (missing:  Protobuf_LIBRARIES Protobuf_INCLUDE_DIR) 
Configuring done

5.点击Generate，生成源码。使用对应的VS打开OSGEARTH项目。

选择OSGEARTH解决方案，右键选择“批生成”

选择ALL_BUILD的Release（可以根据需要选择），点击生成。编译需要2个小时左右，编译完成后，取消ALL_BUILD的Release的选择，重新选择INSTALL的Release，点击生成，这个快。

6.CMD验证。
验证OSG：osgviewer cow.osg

验证OSGEarth：osgviewer simple.earth

7.新建C++项目验证。

配置“链接器”=》“输入”=》“附加依赖项”

	return viewer.run();

收工！待续C#的exe调试C++COM组件。
