Solution 1

Go back to wherever you got the library from, and ask there: they will know their own product much better than we will, and will likely also have sample code that should work.

We can't help you - we have no idea what code you are using at all!

Solution 2

Those are linker errors, not compiler ones.
You did include the proper headers but failed to link with the library.
We cannot help further without more details about your scenario.
