Hello list,

recently I have installed a new octave 3.7.7 on my openSuse 12.3. Now on
the first try outs this octave doesn't find my installed gnuplot.

A simple command plot(1:10) and you get the following error.
error: popen2: popen2 (child): unable to start process -- Datei oder Verzeichnis nicht gefunden
error: called from:
error: /opt/octave/share/octave/3.7.7+/m/plot/private/__gnuplot_open_stream__.m at line 30, column 40

sh: : command not found
error: 'unset' undefined near line 1 column 1
warning: broken pipe

A parallel installed octave version 3.6.3 has no problems to find gnuplot. What's going worng?
Any hints for me?

So long Werner

Hi,

I pulled the latest changesets http://hg.savannah.gnu.org/hgweb/octave/rev/6c62150b454a and cannot confirm your error on Ubuntu 13.04.

:~$ gnuplot --version

gnuplot 4.6 patchlevel 1

:~$ uname -a

Linux XXXXXXXX 3.8.0-31-generic #46-Ubuntu SMP Tue Sep 10 20:03:44 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

This works fine for me with and without using the GUI.

>> graphics_toolkit("gnuplot");

>> plot(1:10)

Can you run demos on gnuplot itself? http://gnuplot.sourceforge.net/demo/
