OSG&OSGEarth編譯心得

編譯OSG

1. 下載數據源
   http://www.openscenegraph.org/downloads/stable_releases/
   
2. 下載最全的（含full）第三方庫
   https://download.osgvisual.org/
   
3. 官網下載源碼
   http://www.openscenegraph.org/index.php/download-section/stable-releases
   
4. 下載cmake-gui
   https://cmake.org/
5. 新建OSG文件夾，將下載好的資源解壓在OSG文件夾中。
   
   新建INSTALL文件夾，用於編譯成功後導出需要的include、lib、data，將三方庫放在OSG文件夾下。
6. 使用cmake生成vs解決方案（根據需要進行選擇）
   
   點擊Configue，進行相關配置。
   
   
   
   

我是按照如上配置進行的，再點擊Configue

這個不管了。下面的我也未處理。

Configuring done

點擊Generate，很快會提示Generating done。
7. 選擇對應版本的VS打開項目，進行編譯。
選擇OpenSceneGraph解決方案，右鍵選擇“批生成”

選擇ALL_BUILD的Release（可以根據需要選擇），點擊生成。編譯需要3個小時左右，編譯完成後，取消ALL_BUILD的Release的選擇，重新選擇INSTALL的Release，點擊生成，這個快。

生成完成之後，在INSTALL的文件下就會出現include、bin、lib等文件夾。

編譯OSGEarth

1.在F盤新建文件件，OSG3.4.0，將3rdarty和編譯好的OSG全部放在這個文件夾下，將data也放在該文件夾下。

2.配置環境變量

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

3.將CMakeLists.txt拖入，Cmake中，點擊Configue

4.檢查全部三方配置，有的都配置好，記得配置INSTALL。

把LINKER後面的內容去掉。再次點擊Configue

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

5.點擊Generate，生成源碼。使用對應的VS打開OSGEARTH項目。

選擇OSGEARTH解決方案，右鍵選擇“批生成”

選擇ALL_BUILD的Release（可以根據需要選擇），點擊生成。編譯需要2個小時左右，編譯完成後，取消ALL_BUILD的Release的選擇，重新選擇INSTALL的Release，點擊生成，這個快。

6.CMD驗證。
驗證OSG：osgviewer cow.osg

驗證OSGEarth：osgviewer simple.earth

7.新建C++項目驗證。

配置“鏈接器”=》“輸入”=》“附加依賴項”

收工！待續C#的exe調試C++COM組件。
