Ogre g++ 编译时错误

Question

在  Ubuntu 下，我编译并按照了所有的 ogre 库，但当我通过命令行编译的时候出错了：

g++ -o otest ogre.cpp -I `pkg-config --libs --cflags OGRE OIS` -lOgreMain -lOI

输出信息：

这是什么问题呢？

Answer 1

ogre 教程里这样：

g++ -o otest *.cpp -I `pkg-config --libs --cflags OGRE OIS`

Answer 2

上述错误是运行时错误，非编译时错误

从出错信息看，你似乎没有编译所有的 cpp 文件，例如 TutorialApplication 的构造函数在哪里呢，你需要编译那个文件。
