Strange interaction between epslatex and wxt???

[Philipp K. J. <ja...@ie...>]

I just seem to have come across a strange
interaction between wxt and epslatex.

Basically, if I have plotted a graph to wxt, then
the files written later (in the same session) 
using epslatex seem to be incomplete. 

This does not occur if I have never used wxt, 
because I was plotting to X11, for instance, or 
because everything was run as a batch job 
(from file).

This does also not occur if I plot to wxt, then
plot to epslatex, then plot AGAIN to wxt. 
Apparently, resetting the terminal and/or
the output flushes everything to file...?

And I have not noticed this kind of problem
with any other terminal (PNG, Postscript, ...).

There is a similar bug (but much less annoying)
on my installation: whenever I have used wxt
in a gnuplot session, and I close the session,
the message "Segmentation fault" is written
to screen. This does not happen if I haven't used
wxt in that session.

Just FYI. Some details below.

Best,

		Ph.

It is not a question of what terminal came before,
but rather a question of what happened after.
(unless, of course, there is indeed a bug we don't know about)

Yes. This is known, well-documented, and basically could
not work any other way.  But it doesn't have anything to
do with wxt.

It is the same with PostScript, and with any terminal
type that can produce an output document containing
more than one plot.  PNG is not an example, but this
would also hit I think SVG, MIF, PDF, etc.

OK. At this point you have opened an latex file and written
one plot to it.  The program does not know if you are going
to add any additional plots, so it still has the file open and
has not yet written the close document statements.
At this point the end of the *.tex file looks like this:
    \gplgaddtomacro\gplfronttext{%
      \csname LTb\endcsname%
      \put(5971,4603){\makebox(0,0)[r]{\strut{}sin(x)}}%
    }%

If you now do

> gnuplot> set term  ... anything
or
> gnuplot> set output ... anything

The program now knows no more plots will be written to the
previous output file. So it finishes off the previous output
file and closes it.  At this point the end of the *.tex file 
looks like this:
    \gplgaddtomacro\gplfronttext{%
      \csname LTb\endcsname%
      \put(5971,4603){\makebox(0,0)[r]{\strut{}sin(x)}}%
    }%
    \gplbacktext
    \put(0,0){\includegraphics{good-inc}}%
    \gplfronttext
  \end{picture}%
\endgroup

Re: Strange interaction between epslatex and wxt???

[Philipp K. J. <ja...@ie...>]

I made a mistake when pasting the gnuplot
session in the previous email. The problem is
NOT a missing "replot" command. Let me try
again - as you can see the problem is specific
to a plot to wxt preceding the plot to epslatex.
It does not happen when plotting to X11 first.

I don't know what to say.
When I use these commands here, I don't get a segfault and I
get a perfectly usable TeX file.  

Tested both with 4.2.2 and with current CVS.

Could you run this under a debugger, or via strace, or even
valgrind, so that we can find out where the segfault happens?

Also the versions of cairo/pango/etc might be relevant.
What is the output of  ldd `which gnuplot` ?

That looks like a legitimate error message, though.
Do you in fact have gnuplot.cfg installed somewhere that
LaTeX knows about?

Re: Strange interaction between epslatex and wxt???

[Philipp K. J. <ja...@ie...>]

Right. I think you mentioned to me once that the
segfaulting problem might have something to do
with the version of libc or another system library,
rather than with wxt itself. (I am running OpenSuse
10.3 on Intel Duo 64 bit. And I am compiling 
gnuplot from CVS.)

Below is the ldd output. Hope that helps.

at this point, maybe you could try:  
gnuplot> set output
which will tell gnuplot to finalise all the open file(s). 

r,

Re: Strange interaction between epslatex and wxt???

[Philipp K. J. <ja...@ie...>]

Yes, you are right. That does work and
flushes the remainders to file.

Still, this is only necessary when I had 
used wxt before - which seems to be
undesirable behaviour. 

(Certainly not the highest priority bug in
the world, although it took me quite a 
while to figure out exactly WHAT went 
wrong for me with epslatex. Now at least
it is documented...)

Best,

		Ph.
