Linux, runtime error, "undefined symbol"

[LordMyth]

Here's the the console output:, first it said plugins.cfg not found, so I took it from /samples/common/bin/release/, and changed the capital letter. I set the plugins path to /usr/local/lib/OGRE/. The DX plugin includes where in the file, so I removed them.

What could that be?

I have never used Ogre in Linux, but undefined symbol errors usually mean, that library and program that uses this library don't match. Make sure you link your application against the correct Ogre version.

I get that error on Windows if the RenderSystem_OpenGL.dll isn't correct (version, correctl location). This could be the same with your .so file.
