Looks, like you try to link a debug build application against a release built ogremain.dll. Make sure, that you link your debug build against ogremain_d.lib.

If you need further instructions, please provide more informations about what you're trying to accomplish.

I think you have to set the c++ options in project settings -> c++ --> code generation ---> runtime libary to multithreaded-dll debuging
