Strange OGRE Errors

[Rishikeshan]

I am a c++ programmer. I am interested in ogre. What are libraries needed to compile first of the beginner's tutorial? I already linked 6 .a files. I could not understand the error. Anyone please help. Thanks in advance.

Error:

Others are from various parts inside OGRE samples and sources.
Thanx in advance. :-/
