Emacs 24 doesn't support semantic-ia-complete-symbol-menu, meaning that I have to use semantic-ia-complete-symbol which shows the suggestions in a new buffer. I have read that there is a way to get auto-complete to use the semantic suggestions, but can't figure out how.
Is there a way to show the suggestions from semantic in some other form than a new buffer, e.g. as a menu, inline, etc?
Don't know about auto-complete, but company-mode (which is in GNU ELPA, hence can be installed directly via M-x package-install) provides this out of the box.
