What is this mean?

It means that you are calling a function that is declared, but has no body. This usually happens when you include a lib header file, but the linker cannot locate/include this lib file at link time. Check all your path settings/etc to check of the linker can find the lib file.

Hi !!
I set all the paths and properties in the project properties.But still it is showing the linker errors.and it is showing at some functions in some libraries.But those functions are also available in libraries.
Some of the errors i am getting are....
