I have multi files and each file refers to the master file properly and the document can be compiled without problems .... RefTeX can only refer to the environments , figures, equations, etc when it is stated in the master file ... rather than this C-c ) can't see the other labels in any other file than the master ... kindly advise.

The following are the minimal files

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

\documentclass{book}
\begin{document}
\chapter{chapter 1 }
\label{cha:chapter-1}
\ref{cha:chapter-1}

\end{document}

and the second file slave.tex

\chapter{Chapter 2 }
\label{cha:chapter-2}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "master"
%%% End:

The reference only can see the labels in the master file , and C-c ) when invoked from the slave.tex can't recognize the label to the chapter in the same file..... ;; If there is more than one, they won't work right. )

Edit 1: Forgot to mention that I import and include the slave into the master file. It is pretty complex on my side as with this minimal file, I am able to reference whatever exists in master only or slave only. On the main document I am building, I am able to reference only whatever is in the master!

Edit 2: The problem was mainly due to using \import to include the files rather than \input. I noticed also that there is a need to reset RefTex every time I try to add a new file. I will try also to check \cite and whether it is updated in the new scheme. I will also keep using the init.el that you sent... again thanks a lot Jon and I do appreciate this feedback and resolution very much...

  • @mosalem2003 -- You don't need to use the init.el file I included in my answer below: I only included it to show that the answer will even work with your original init file (myinit.el is identical except for all the predictive stuff, which I don't have on my computer). One other point, if my answer resolved the problem in your opinion, you should click on the checkmark beside the answer to mark it as 'resolved'; you can additionally 'upvote' it if you like, but marking the problem as solved gets this question off the unanswered list.

The basic problem is that the masterfile does not actually make any reference to the supposed sub-file, so it is impossible for any program to know it needs to think about a masterfile-subfile relationship. In AUCTeX' case, parsing kind of works from the subfile because it has a variable informing AUCTeX of the masterfile (but you'll note that AUCTeX/RefTeX do not parse the subfile itself, so it is hardly that useful).

But things work as expected if you do \include or \input a file in the subfile. E.g.:

masterfile.tex

\documentclass{book}
\begin{document}
\chapter{chapter 1}
\label{cha:chapter-1}

\input{subfile}% <-- crucial!

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t 
%%% End:

subfile.tex

\chapter{Chapter 2}
\label{cha:chapter-2}
\label{anotherlabel}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "masterfile"
%%% End:

Now C-c ) <SPC> should give a list of (in this case) three labels. This will even work with the init file provided above, although I had to comment out a few things. You can use the following to test (assuming the provided file is called myinit.el):

emacs -q -l myinit.el masterfile.tex 

myinit.el
