Ogre g ++编译时错误

Question

在ubuntu上，我编译并安装了所有的食人魔库。但是，当我尝试使用此命令编译教程时

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

并输出

任何人都知道如何解决这个/我做错了什么？

Answer 1

这不是编译时错误，而是链接时错误。

从外观上看，您可能没有编译所有*.cpp个文件。什么文件是TutorialApplication的构造函数的主体？你需要编译并链接它。

Answer 2

这适用于食人魔教程：

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