How to calculate the change in entropy for a non ideal gas?

Im looking at using what we call Tds relations

Tds = du+PdV

and apparently integrating this will get the change in entropy. I dont know how to do this and how it would work? Where do you substitute in values for pressure, temp etc. Could someone please shed some light on this?

I also know gibbs equation could that be used for non ideal gas?
