 TeX-view does not jump to correct place in PDF file, texlive 2015
Date: Thu, 25 Feb 2016 18:21:33 +0000

Hi

That looks bizarre. I am still using Kubuntu 10.04 which ships texlive
2009. Everything works fine, in my current setting TeX-view jumps to the
      correct place in the pdf file, when running pdflatex.

However I *also* installed in  (/usr/local/texlive)

Texlive 2015 and following the instructions found in
https://tex.stackexchange.com/questions/1092/how-to-install-vanilla-texlive-on-debian-or-ubuntu

I do

mkdir -p /opt
sudo ln -s /usr/local/texlive/2015/bin/* /opt/texbin
and then

In /etc/environment I
modify
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
to 
PATH="/opt/texbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

So far so good, but when I now use auctex in GNU emacs with the same
setting, the pdflatex compiling is fine but
TeX-view only jumps to the beginning of the pdf file!!

This is rather annoying. What can I do?

Regards

Are you sure Emacs has the right values of `exec-path' and (getenv
"PATH")?  In addition, did you try to clean all auxiliary files and
recompile with pdflatex from TeX Live 2015?  I don't know, maybe the
format of SyncTeX files slightly changed in the meantime and are
forward incompatibles.

Bye,
Mosè

No problem, I switched back to 2009 for the moment, since I need the
forward search very much.

Good question, how can I check?

Maybe not. I will try that, but before I want to check the path as you
said.

    C-h v exec-path RET

    M-: (getenv "PATH") RET

Are you really telling me you never used C-h v to check the value of a
variable? ;-)

I did this and  I compiled again.

Search forward does not work, emacs opens (okular) always at the first
page.

Odd, no?

Yes, it's weird, it works for me flawless with Okular as viewer and
TeX Live 2015 installed with the same method.  In a LaTeX buffer, what
does

    (TeX-synctex-output-page-1 (buffer-file-name))

return for you?  If it returns nil, it would be great if you could
edebug the function `TeX-synctex-output-page-1'.

You are not going to belive this. With TL 2015 this variable is *not*
nil but some number (string)


For example if you execute it at the beginning of the buffer it returns

 "1"
 and if I do it at the end of the buffer it returns "25"

However C-c C-v and okular jumps to the first page.

I switched back to TL 2009.

Now that variable is *always* nil, but
However C-c C-v and okular jumps more or less to the line which
corresponds to the source code.

I am puzzled

Looking better to the code, I'm not surprised at all: AUCTeX doesn't
pass the page number to Okular, so that function isn't even evaluated
(it is used for Evince and xpdf, not for Okular).  In the LaTeX
buffer, issue C-c C-c View RET, what's the command proposed in the
minibuffer?  Is it different between when you use TeX Live 2009 or
2015?

I thought the setting

 '(TeX-view-program-list (quote (("okular" "okular -unique %o#src:%n%b"))))

Does that


    > buffer, issue C-c C-c View RET, what's the command proposed in the
    > minibuffer?
For example

okular --unique eulerpoisson.pdf#src:2449"/home/oub/eulerpoisson.tex"
 or 
okular --unique eulerpoisson.pdf#src:29"/home/oub/eulerpoisson.tex"

    > Is it different between when you use TeX Live 2009 or
    > 2015?

No, but I think I found the source of the problem.

In the command line I fired up
okular --unique eulerpoisson.pdf#src:2449"/home/oub/eulerpoisson.tex"

Okular opened the pdf file at the first page.

I copied the pdf to eulerpoisson-2015.pdf

I changed the envrionment back to TL logout login

And
okular --unique eulerpoisson-2015.pdf#src:2449"/home/oub/eulerpoisson.tex"

And okular opened at page one.

I recompiled the latex file, with pdflatex TL2009, now 
okular --unique eulerpoisson.pdf#src:2449"/home/oub/eulerpoisson.tex"

 opened correctly the pdf file 

So it seems that okular (at least the version I have) cannot deal
correctly with the pdf generated by TL2015.

So it is not really auctex fault, but I love to hear a work around, I
think I did use evince because there inverse search does not work.

As expected, because synctex looks for the .synctex.gz file with the
same base name of the .pdf file, and can't find it in this case

I'd avoid renaming files, to start with.  Did you compare the synctex
files between two TeX Lives versions?

Ok, I put the latex file in 2 different directories TL2009 and TL2015
and run it either with TL2009 pdflatex or TL2015

Then I run in both directories the command 
okular --unique eulerpoisson.pdf#src:940"/home/oub/TL2015/eulerpoisson.tex"

In TL2009 it opened where it should in TL2015 not

Yes there a subtle difference:

 TL 2009 eulerpoission.synctex starts with

Input:1:eulerpoisson.tex

While 2015 has:

Input:1:/home/oub/TL2015/./eulerpoisson.tex

I am worried about the /./

Then comes a lot of style files which sit in different locations of
course.

I'm not, because of course I have the same (same version of TeX Live)
and forward/inverse search works great for me.  It's known SyncTeX
changed this syntax over time, we have some comments about it in
`TeX-synctex-output-page'.  Maybe your Okular version is so old that
doesn't cater for the change of syntax.  Okular 0.23.2 here.

Anyway, I'm closing this issue, AUCTeX isn't involved at all since you
have the same problem when running Okular from the command line.

Bye,
Mosè
