Not /auto/ completion, but `completion-at-point' is bound by default,
and you can configure `tab-always-indent' to have TAB provide
completions as well.  They will pop up in the completion buffer, just
like with minibuffer completions.

I am not sure if Emacs 26 had completion based on TAGS, but if Emacs was
installed using some standard mechanism, then you should have etags
available that could index the symbols in a project, that completion
could make use of.
