No, you should not glue your laminate to the subfloor. Most laminates are a floating floor, and should be able to expand and contract freely. Since it is a floating floor, it is meant to support itself via locking systems and have no connection to the subfloor.
The sub-floor must be perfectly level and damp-proof. Most probably it will be necessary to use a leveling compound and an appropriate damp proof layer. In addition, you will need a resin that provides sufficient adherence to the Laminate backing.
For staircases, you will need to glue and screw (or nail) the laminate down to the stairs themselves. The glue should be a Liquid Nails® or “construction-type” glue dispensed from a glue gun. If you are looking for flooring with a glue down installation, you will need to purchase glue down flooring.
