I'm trying to get omnicomplete to work for C++, and while everything seems to be in order, when I reset my omnifunc to be omnifunc=omni#cpp#complete#Main, the plugin does not recognize the omnifunc, and I get a pattern not found error. I've installed Ctags and put it in .vim/<name_of_dir>, along with adding cpp_src to .vim/tags and running the necessary commands. (see here for more info)
The issue is that, no matter what I try, I still get this error. What can I do to get this working? I've tried this before, and the first time has just been a headache which resulted in me not being able to get it to work. This time, however, I'm determined.

As always, any help is much appreciated.
Update
Posting my Ctags file for others to inspect in case there is an issue with that:
ctags -R --c++-kinds=+p --fields-+iaS --extra=+q .
map <C-F12> :!ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .<CR>
Obviously, Vim can't find your tags file. Your command ctags -R --c++-kinds=+p --fields-+iaS --extra=+q . will create tags file in current directory. Make sure that this is what you want.
Please execute the following command:
:set tags?
and make sure your tags file is present in resulting list. You can also place cursor at any symbol (say, some class name) and press Ctrl-]. Vim will jump to this symbol definition if your tags is OK. If it is not, then, of course, omnicppcomplete will not work. (I use omnicppcomplete for more than year, and it works. Not perfectly with complicated classes/structs, but works.)
And, finally, check my answer here, because i would recommend absolutelly the same: to get perfect C/C++/Objective-C code completion you should use Clang Complete (no ctags is needed for this kind of completion).
And if you want tags to be present (say, to easily jump to symbol definition), please use Indexer plugin.
