I tried kodi 17.3 both in Slackel 64-bit and 32-bit. It works flawlessly. It even works in machines I wouldn't expect it to work properly, like a 9-years old netbook with very limited resources, running Slackel 32-bit. I actually used that netbook to watch a few movies with kodi, and I didn't notice the slightest problem.
By the way I noticed that several independent package repos for Slackware already include djemos' kodi packages, saying they come from Slackel. Kodi is very popular, so they spotted them quickly.
