Can anybody help me why it is happening ?? I am really confused in this error. When OgreAL project run then OgreAL_d.dll is created and it is automatically coppied to the directory Demos/bin/Debug. This path is already set to every demo.

is folder that contains OgreAL_d.lib is in project properties -> Linker -> additional directories?

Thanks Pra for reply...
but problem is that how I get the OgreAL_d.lib. When I run the OgreAL project that time OgreAL_d.dll is creating only.
