OSG ifstream及ofstream错误
我是在ubuntu下搭建的qt5.9.1+osg3.2.2的环境，我在尝试进行osg编译时出现这样的错误/usr/local/include/osgDB/fstream:35: error: invalid use of incomplete type ‘std::ifstream {aka class std::basic_ifstream<char>}’
class OSGDB_EXPORT ifstream : public std::ifstream
^
以及
/usr/local/include/osgDB/fstream:47: error: invalid use of incomplete type ‘std::ofstream {aka class std::basic_ofstream<char>}’
class OSGDB_EXPORT ofstream : public std::ofstream
^
各位大佬有没有解决的办法啊
下面是我找到的代码，但是我觉得我的代码肯定没问题啊
#include<QApplication>
#include<osgDB/ReadFile>
#include<osgViewer/Viewer>
int main()
{
osgViewer::Viewer viewer;
viewer.setSceneData(osgDB::readNodeFile("/home/pangpang/OpenSceneGraph-3.2.2/cow.osg"));
viewer.realize();
viewer.run();
}
