I built ACE-5.6 in Ubuntu Linux. The headers and sources live in /usr/local/include/ace and the libraries go to /usr/local/lib.

To simplify the words below, let ACE_INCLUDE represent /usr/local/include/ace.

-- Build tags

ACE_INCLUDE$ sudo ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .

-- Install scrīpt OmniCppComplete for Vim

You can find it here: http://www.vim.org/scrīpts/scrīpt.php?scrīpt_id=1520

Configuration for it in my .vimrc:

"-------------------------------------------------------------------------------
" plugin - omnicppcomplete

let OmniCpp_NamespaceSearch = 2 " search in included files too
let OmniCpp_DisplayMode = 1 " always show all members for class scope(::)
let OmniCpp_ShowPrototypeInAbbr = 1 " useful for overloaded functions
let OmniCpp_MayCompleteDot = 1 " default 1
let OmniCpp_MayCompleteArrow = 1 " default 1
let OmniCpp_MayCompleteScope = 1 " default 0 (::)
let OmniCpp_SelectFirstItem = 0 " default 0

-- Build cscope.out

ACE_INCLUDE$ sudo cscope -Rbk *.h *.cpp *.inl

-- Add a function in .vimrc to add those databases

function! ACE_AddDB()
    if filereadable("/usr/bin/ctags")
        set tags+=/usr/local/include/ace/tags
    endif

    if has("cscope") && filereadable("/usr/bin/cscope")
        if filereadable("/usr/local/include/ace/cscope.out")
            cs add /usr/local/include/ace/cscope.out /usr/local/include/ace
        endif
    endif
endfunction

Note the second argument of 'cs add'. It's important.

You can call it via :call ACE_AddDB() or bind a key to it.

The reason why I don't add them directly is for Vim's performance. I don't want unnecessary databases to be added until I am really working on a ACE project.
