[Gnuplot-info] qt terminal hangs in gnuplot 5.0

[Elias A. <eli...@gm...>]

Hi List,

I have successfully compiled gnuplot 5.0.0, and the ‘wxt’ and ‘x11’
terminals work fine.  But when I try to plot something with the ‘qt’
terminal, gnuplot complains

    gnuplot> p [-4:4] sin(x), [0:pi] cos(x)
    Could not start gnuplot_qt with path 
"/usr/local/libexec/gnuplot/5.0/gnuplot_qt"
    Could not start gnuplot_qt with path 
"/usr/local/libexec/gnuplot/5.0/gnuplot_qt"
    Could not connect to gnuplot_qt "" . Starting a new one
    Could not start gnuplot_qt with path 
"/usr/local/libexec/gnuplot/5.0/gnuplot_qt"

    Warning: slow font initializationgnuplot>

This looks like the error that was reported on Cygwin
<http://sourceforge.net/p/gnuplot/mailman/message/33209231/>, but I am
on an Ubuntu system.  I see the same behavior whether I compile with
Qt4 or Qt5.

Any pointers?
