I found a previously supplied answer (see below). I think some mention of "filetype plugin on" should really be included in the help for omni completion.
-------------------------------- > E764: Option 'omnifunc' is not set. You have to put "filetype plugin indent on" in your .vimrc file (or without the "indent" part). Although this function is explained elsewhere in the docs, I don't think the omni doc itself says that you have to do this. It mentions that the filetype plugins will set omnifunc, but doesn't actually mention that you need to tell vim to use these plugins. The docs make it sound automatic. I had the same problem, and I doubt any new user, nor anyone who didn't already know about the :filetype command, would be able to figure out how to get it to work. -- View this message in context: http://www.nabble.com/problem-using-omni-completion-t1723473.html#a4683008 Sent from the Vim - General forum at Nabble.com.
