Re: [Plplot-devel] prescription for loading tkwin driver?

[Alan W. I. <ir...@be...>]

I was pleased to see you have gotten package require Plplotter to work.  It's
amazing how the machine couldn't figure out what I meant by autopath....;-)

I was able to do ./x01c -dev xwin with the installed libraries a few days
ago, but I also confirm it no longer works now with -dev xwin.

I have looked at your changes and see nothing to disagree with.  So it is a
puzzle.  But I believe I can figure out what is going on since that error
message comes from just one part of the plplot core code.

As far as the static drivers are concerned, the xwin, tk, and tkwin drivers
should all be merged into libplplottcltk (I think that is already taken care
of with the present configuration), and the rest merged into libplplot (I
suspect the current configuration would merge all drivers there which would
be a mistake).  The linking of libplplottcltk and libplplot would also have
to be changed to accommodate the special libraries required by the various
drivers.  So it shouldn't be that bad (he says...;-)), and I encourage you
to give it a try.
