osg::ref_ptr<osg::Camera>master=new osg::Camera;
        master->setGraphicsContext (gc);
        master->setViewport (0,0,800,600);
        viewer->addSlave(master.get());

        osg::ref_ptr <osg::Camera>rttCamera=new osg::Camera;
        rttCamera->setRenderOrder (osg::Camera :RE_RENDER);
        rttCamera->setGraphicsContext (gc);
        rttCamera->setViewport (0,0,800,600);
        rttCamera->addChild (osgDB::readNodeFile ("ceep.ive"));
        viewer->addSlave (rttCamera,false);

代码加上viewer->addSlave(rttCamera,flase)就出现DEBUGdetected OPENGL Error 'invalid value' at start os State::apply<>是哪里出错了

我不认为Slave Camera可以用来做RTTCamera，请参考各类书籍以及osgRecipes上的例子
