Hi David:

In my case, it was configuration of a new computer which kept me from
replying to what you said above in a timely way.  My apologies for that
delay.  But that new computer configuration has now been a success (I
am writing this from the new computer and PLplot also builds
on that new computer) so I now have a chance to answer you.

I think the nmake trouble you are having is due to the (default) install prefix
"C:/Program Files (x86)" having a blank in the path.  I think all those "blank 
in
path" issues are now gone in the git version of PLplot so please try that not
only for that reason but also because that is the version of PLplot I test with
in any case.

I tried a similar test (copying simple.cpp on top of 
examples/c++/wxPLplotDemo.cpp) here,
but in my case I configured PLplot with the cmake option -DBUILD_TEST=ON which
allows users to test in the build tree without having to install.  The result 
on
my new Debian Buster platform was I could build and run simple.cpp using
"make test_wxPLplotDemo".  That test had two key warnings which were

Gtk-Message: 22:23:32.181: GtkDialog mapped without a transient parent. This is 
discouraged.

on the command line + a dialog box with the following contents:

"Somehow we attempted to plot before the wxPLplotwindow was ready.  The plot 
will not be drawn".

And indeed that was followed by a blank plot.  So it appears your simple.cpp is 
still
not set up correctly for the Linux case.

I have put this thread back on the plplot-general list because Phil
Rosenberg, the author of the PLplot wxwidgets binding and device may
wish to comment since he had similar "waiting for events" trouble in
the past on Linux which might be related to what I am seeing on Linux with
the current simple.cpp.
