C++ 在MSVS2012中使用osg标头时出现错误LNK2019未解析的外部符号

C++ 在MSVS2012中使用osg标头时出现错误LNK2019未解析的外部符号,c++,lnk2019,unresolved-external,openscenegraph,C++,Lnk2019,Unresolved External,Openscenegraph,我正试图编写一个学习使用osg的示例程序,但通往成功的道路似乎一如既往地艰难 代码如下: #include <windows.h> #include <osgDB\ReadFile> #include <osgViewer\Viewer> int main() { osgViewer::Viewer viewer; viewer.setSceneData(osgDB::readNodeFile("cessna.osg")); return

我正试图编写一个学习使用osg的示例程序,但通往成功的道路似乎一如既往地艰难

代码如下:

#include <windows.h>
#include <osgDB\ReadFile>
#include <osgViewer\Viewer>

int main()
{
   osgViewer::Viewer viewer;
   viewer.setSceneData(osgDB::readNodeFile("cessna.osg"));
   return viewer.run();
}
附加依赖项

还选择了调试模式


尝试编译时,我会遇到多个类似错误:

(很抱歉代码中有一些德语表达,我尝试翻译了其中的大部分。)

有人知道怎么解决这个问题吗?
提前谢谢。

我不知道这个库,但可能是32位与64位不匹配?但我怎么才能发现呢?首先,您是否运行64位Windows?如果是这样,请将您的项目更改为针对64位Windows构建,然后重试。最后,这就是解决方案。我真丢脸。但是谢谢你提醒我这么简单的事情。
