How do I get Vim Omni Completion working in Makefiles?

Question

I'd like to be able to use Vim omni-completion in Makefiles, so that I can get auto-complete for target dependencies and such. Anybody know how to do this?

Answer 1

I'm not sure about omni-completion, but you can use normal completion in Vim.

For example if you have a target called 'installdocs', you can type:

ins<C-n>

and Vim will complete the target name for you.
