Vim, Omni Completion and the mess of directories under Windows

I was following this: http://vim.wikia.com/wiki/C++_code_completion

At some point it says that when you type something like std:: "A box opens with suggestions."

In my case as soon as I type std:: I get a message in the bar at the bottom: Omni Completion (^O^N^P) Pattern not found

This may as well be a mess because no tutorial explains where things go in Windows.

For example: before I can install OmniCompletion, I have to install ctags. How? I have no idea. At some point I read that I only need ctags.exe under windows. But where do I put it? I figured out to put it in the mingw/bin/ directory since it was already in the path.

And it seems to work. Though when I press C-12 instead of indexing the current file, it seems to start indexing my whole home directory in Windows.

Every time I opened a .cpp file it kept saying "Pattern not found".

I eventually figured out that it works IF I edit a specific file by right clicking on it, and pick "edit with Vim" from the menu. If instead I launch Vim from its shortcut and THEN open a .cpp file, OmniCompletion fails.

The reason seems to be that "edit with Vim" gives the program the correct working directory, but if I then open a file that exists somewhere else, OmniCompletion stops working and says it can't find anything.

So, under Windows, what is that tells Vim in which directory to operate, so that I can edit properly different files no matter where they are, and no matter how I opened Vim in the first place?

And how can I run ctags so that it does its job in the current directory where the active file is, instead of wherever it randomly pleases?

Vim's working directory is inherited from where you start Vim, or else defaults to your $HOME directory. I don't know much about omnicompletion, but it sounds like your problems could be fixed by setting

:set autochdir

This means Vim's working directory will always be that of the file you are editting.
