M-x list-tags gets [No match]

[Liang Wang]

Hi,

When I run M-x list-tags TAB, I get [No match].

Here is the way I create TAGS file for Emacs source tree.

$ cd src
$ etags -o TAGS.sub *.[hc]
$ cd ../lisp
$ etags -o TAGS.sub *.el
$ cd ..
$ etags -i src/TAGS.sub -i lisp/TAGS.sub

If I create TAGS file in the following way, M-x list-tags TAB works fine.

$ etags src/*.[hc] lisp/*.el

Is the first way I create TAGS file wrong?

Thanks,
Liang.
