osg帧率显示编译错误

拽拽熊孩子

代码是照着书上来的。结果出错了，代码如下：
#ifdef _DEBUG
#pragma comment(lib,"osgViewerd.lib")
#pragma comment(lib,"osgDBd.lib")
#pragma comment(lib,"OpenThreadsd.lib")
#pragma comment(lib,"osgd.lib")
#else
#pragma comment(lib,"osgViewer.lib")
#pragma comment(lib,"osgDB.lib")
#pragma comment(lib,"OpenThreads.lib")
#pragma comment(lib,"osg.lib")
#endif

#include <osgViewer/Viewer>
#include <osgDB/ReadFile>
#include <osgViewer/ViewerEventHandlers>
#include <osgGA/EventHandler>

int main()
{
        osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer;
        viewer->addEventHandler(new osgViewer::StatsHandler);
        viewer->setSceneData(osgDB::readNodeFile("glider.osg"));

        return viewer->run();
}

应该就是粗线那句出错，把他注释掉就没错了。
这是vs报的错误：

osg编译的应该没问题，因为我运行 osgviewer cow.osg,能出来奶牛，也能按s显示帧率。新人小白一个，求大神帮忙看下是怎么回事？

osgGA的库路径好像没有配置
