[Plplot-general] Status of yplot

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

As some of you may recall, yplot (yplot.sf.net) is an extension of the
Yorick language that makes it possible to use PLplot from Yorick.  yplot is
maintained essentially be me, although Conrad Steenberg, its originator
still has a bit of input.  Some time ago we decided to only do minimal
maintenance of yplot (because we thought Yorick was in that maintenance mode
as well), and yplot just continued to work fine through all the various PLplot
releases.  However, it now appears that Yorick development continues pretty
strongly, and I have just discovered the new Yorick-2 completely breaks the
build of yplot.

Accordingly, I am currently working on the yplot build (with a new yplot
build system that takes advantage of CMake), but I have run into a Debian
yorick packaging bug that is an absolute showstopper for generating a yplot
executable (the desired end result which is a version of Yorick with PLplot
extensions).  (This problem is caused bysome binary incompatibility or
binutils bug which I cannot figure out or workaround.) Until my bug report
is answered, I must fall back to using the alternative dynamic loading
mechanism of Yorick-2 plug-ins which requires a one-line change in each of
the *.i yorick include files I use for my research plotting.  Once that
change is made, everything seems to work OK again, but I don't want to
impose that change on the remaining yplot users, and I am pretty far from a
new release of yplot in any case.

Nevertheless, if someone still wants to plot with yplot but cannot do so
because they have Yorick-2 installed, then please get in touch with me
privately, and I can instruct you how to build and use the Yorick-2
compatible yplot that I have cobbled together at the moment.
