Compiling
well on the top row of stuff in the editor is a drop down menu called BSP
When you’ve made your sealed (from the outside) room etc put all the relevant entities in it and set worldcoordmins/maxs then press BSP and choose the top option META. For miore help i recommend visiting the following sites

that means that your map is not sealed, as in an entity or detail brush is able to touch the void (or a line can be drawn from an entity/detail brush into the void). The void is everything that is not your map. Its hard to explain. When you load radiant all that space that is empty is like a big void. You must seal everything inside your map using structual brushes. I really recommend that you follow some of the basic tutorials exactly. The easiest way to stop leaks until you become more familier with radiant is to draw out a massive box completly surrounding your map and hollow it out using the hollow button.
