That's not the compiler giving the error, it's the linker. It needs to
reference the lib file for the library you are calling - you need to
reference it in your project.

I do have the Library's that are needed and i have linked them. The the
functions and the class on which the linker is complaining is part of the
project..

So i am not sure on what may be causing that problem...
