VIM - omnicppcomplete

I had to put these in my ~/.vimrc to get omnicppcomplete to work

autocmd BufNewFile,BufRead,BufEnter *.cpp,*.hpp set omnifunc=omni#cpp#complete#Main

"ctags
map <C-F12> :!ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .<CR>

"omnicppcomplete
imap <C-Space> <C-x><C-o>
let OmniCpp_MayCompleteDot = 0
let OmniCpp_MayCompleteArrow = 0
