You did understand. That's it.

Yes, today's find-tags bug is due to the fact that in case of error the TAGS file is not used at all.

Now I do not use any more a soft link.

It does not.

I repeat.

I use a LINK to TAGS file from src/TAGS.

More precisely, look ls -al in ./emacs directory

lrwxrwxrwx  1 root root      8 2007-04-18 05:56 TAGS -> src/TAGS
lrwxrwxrwx  1 root root     13 2007-04-18 05:56 TAGS-LISP -> src/TAGS-LISP

I do so:

M-. re-fr-st <TAB> insert here the path to TAGS file FROM EMACS DIRECTORY, NOT FROM ./EMACS/SRC.

In this case it does not work.

If I complete the path to the TAGS file from ./emacs/src/TAGS , it works.

So the only problem is that etags does not work if we work to a sym-link to the TAGS file. We must use the path to the original TAGS file. This is the but. This is the same bug as that one reported by me here:

<<lwlib>>.

That is. True.

Or to write in TAGS file the complete path, not a relative path.

ok.

That is. I solved it. I have emacs installed in /gnu/emacs/ and I used a soft link from /gnu/emacs/src/TAGS to /gnu/emacs/TAGS.

in TAGS there is a line 

../lwlib//TAGS,include

and from here the error was born.


Now it is clear.

So in the actual form if we can try to use a soft-ling to the TAGS files, tags do not work any longer.
