Package: maxima
Version: 5.33.0-3
Severity: normal

Dear Maintainer,

I am running the kde desktop on jessie and installed the gnuplot and maxima
packages.
Gnuplot uses the terminal option qt by default, whereas maxima wants the wxt
terminal,
which is not installed by default. Thus I get the following error when I plot.

 Maxima 5.33.0 http://maxima.sourceforge.net

 (\%o1) \verb|/home/yves/maxout.gnuplot_pipes| \\ \verb| |
 gnuplot> set term wxt size 640,480 font ",12"; set term pop
                   ^
          line 0: unknown or ambiguous terminal type; type just 'set terminal'
for a list

I can fix it by issuing the command

 set_plot_option([gnuplot_term, qt]);

I am not sure however why maxima wants to use the wxt backend with gnuplot.
I didn't install wxmaxima, the wxt backend is not available by default with a
gnuplot install under kde, neither is the library libwxbase. My feeling is that
the maxima package should not rely on wxwidgets by default for plotting. At
least it should check for the availability of the backend.

Best regards.

Subject: maxima wants wxt as backend for gnuplot
Date: Tue, 1 Jul 2014 03:42:25 +0200

In earlier versions of gnuplot packages in debian, the wxt terminal
would work regardless whether gnuplot-x11 or gnuplot-qt was installed.
But it was recently disabled in gnuplot 4.6.5-4 to fix bug #750045.
