Tub spout question

I'm almost done remodeling my main bathroom. One of the things left to do is attach the tub spout. For some reason, I ordered one with threads as opposed to the slip-on type. The copper supply pipe coming out of the wall has no threads. Do I have any other options besides sweating a threaded adapter thingy on the end of the pipe? Maybe a compression fitting?

spout

A compression fitting will "slip" when you tighten the spout on. If your spout has the threads at the front then you have enough room to solder an adapter onto the copper. If the threads are at the back side next to the wall, then you either need a flush adapter, which can be hard to find, or a different spout.

Thanks - I kind of suspected that.

Get the pre soldered male adapter from Home Depot. All you have to do is flux and then hit it with a torch.
