the first two likely reasons that spring to my mind are:
1. The stl describes only a surface. If you want a volume to be meshed,
you have to declare a volume in gmsh. To do this, chose the geometry
menu, add a volume, select the surface to define a volume from it.
2. The stl might have holes. You would need to plug these first.
Hope this helps.
