环境:Vs2010
OpenSceneGraph-3.0.1-VS10.0.30319-x86-debug-12741
OpenSceneGraph-3.0.1-VS10.0.30319-x86-release-12741
设置环境变量
PATH: D:\osg\bin
OSG_FILE_PATH: D:\osg\data
这时候你可以用osgViewer查看一下osg文件,比如经典的奶牛cow.osg
在命令行下输入:osgViewerd.exe cow.osg
新建一个vc空项目,设置vc++包含目录和库目录。vc2010是右击|属性|项目和解决方案|VC++目录,低版本是工具|选项|项目和解决方案|VC++目录
包含文件: D:\osg\include
库文件: D:\osg\lib
右击|属性|配置属性|链接器|输入|附加依赖项
OpenThreadsd.lib
osgd.lib
osgDBd.lib
osgViewerd.lib
如果编译Release版本,去掉d
新建main.cpp输入下面的代码,这次显示一个滑翔机。
#include <osgDB/ReadFile> #include <osgViewer/Viewer> void main() { osgViewer::Viewer viewer; viewer.setSceneData(osgDB::readNodeFile("glider.osg")); viewer.realize(); viewer.run(); }

编译出现的问题:d和非d的lib
过程中出现的问题:Microsoft C++ 异常 std::bad_alloc
0x7c812afb 处未处理的异常: Microsoft C++ 异常: 内存位置 0x0012f448 处的 std::bad_alloc。
原因:编译Debug版本的时候使用了不带d的Dll。
处理方法:
Demo编译成Debug版本使用带d的dll,编译成Release版本使用不带d的dll。
注意:
1. 编译Debug和Release版本需要分别设置项目属性中的包含目录文件和库目录。
2. 分别设置“链接器——输入——附加依赖项”,或者输入如下代码:
