linking to headings with a unique I'D exported to latex/PDF

linking to headings with a unique I'D exported to latex/PDF

I'm writing a document which is exported to latex and then built into a
PDF where I might have 'Alcohol', just as an example, mentioned several
times in different level headings. Currently I'm using org links like
this [[*Alcohol][Alcohol]] but that only allows me to link to one
heading only.

I've tried using links like this
[[id:542d0880-c0fd-46d5-b75d-4cc6f5fa99cc][Alcohol]] and under the
heading that I'm linking to it says -

--8<---------------cut here---------------start------------->8---
*** Alcohol
:PROPERTIES:
:ID:     542d0880-c0fd-46d5-b75d-4cc6f5fa99cc  
:END:
--8<---------------cut here---------------end--------------->8---

But when exported it does not work.

So, how can I link to specific headings, preferably with a unique ID
please?

Thanks
Sharon.

The example that I've just given with the ID.

Thanks

This works for me:

#+begin_example

* Alcohol
  :PROPERTIES:
  :ID:       c8f90f00-4e36-41b7-b7fe-e52966e36d1d
  :END:

Something

\newpage

* Another heading

Blah blah blah, see [[id:c8f90f00-4e36-41b7-b7fe-e52966e36d1d][Alcohol]]

#+end_example

From page 2 I jump up to the page 1 alcohol heading.

Not sure if you need it, but I'm assuming you load org-id?

Input: a reproducible example is best. With just pasting the id and
what the Alcohol heading says, it still leaves other things open to
chance... best would be a minimal config, minimal .org file contents,
and org version. Just my opinion. Otherwise a lot of emails are traded
just making sure everyone is on the same page. With the things I've
listed people can create an approximately matching setup to just try
it rather than guess at how to recreate what your'e describing.

I ran into a problem like this a week or two ago, where [id:xxx] links
were not working.  Michael Welle suggested loading org-id and that
resolved my problem.

I do think however that the message I was getting was unhelpful
(something like "Link not found. Create a new heading?"), even though
there was nothing wrong with the link.

Nothing that I tried worked, yes, I was using 'org-id', but it was still
failing, so I set about building a MWE.

And then I found the problem - the latex package called 'titlesec' when
used with org-mode to latex is incompatible with org-mode and stops
org-id from working. Comment it out and org-id works perfectly again.
What 'titlesec' does is compress the space around each header, so its a
latex problem not an org-mode problem, so I shall look for a latex
solution to compressing the header spaces.

Thanks for all the suggestions and ideas to solve the problem.

Sharon.
