Vim fails to set omnifunction with clang

Question

I understand that clang can be used in place of omnicppcomplete. However, after installing clang, vim fails to autocomplete on scripts specified in the vimrc. i.e. previously, autocmd FileType python set omnifunc = pythoncomplete#Complete in the .vimrc file worked fine.

After installing clang, however, it returns this error whenever I open a file:

Error detected while processing FileType Auto commands for "python":
E518: Unknown option: pythoncomplete#Complete

I tried to remove the clang directory as well, but the error remains. Any idea?

EDIT: Realized after much debugging that you can't leave spaces between the '=' sign. So the proper method would be 'autocmd FileType python set omnifunc=pythoncomplete#Complete'.

Answer 1

Vim treats the pythoncomplete#Complete as another setting (that does not exist), because you've accidentally included a space around the =. You can change multiple settings with the :set command.
