You need to include the Line3d.h/cpp files into the project.

ok , i do , i add the line3d.cpp and line3d.h to my project , and it built succeeded , but i tried to run , one strange error came up

i just finish to replace the the ogremain.dll , with C:\OGRE\ogrenew\OgreMain\lib\Release\OgreMain.dll

and the error changed!

You don't have your game thing setup correctly. Make sure to copy in all dll's and setup your config files properly.
