[Plplot-general] Static driver problem for PLplot-5.2.0 has been diagnosed and fixed in CVS

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

The reason for the problem has been found and the fix is in CVS.

It turns out the fatal combination is static drivers and --with-double on
*all* platforms.  (We gave the mistaken impression before this problem only
occurred on some platforms.) Thus, for any platform a workaround is to
specify --enable-dyndrivers.  An alternative workaround is to avoid
specifying --with-double.  Its a Boolean OR of those two workarounds. Thus,
the combination of --enable-dyndrivers and --with-double builds fine since
the first workaround condition is fulfilled.  Similarly, default options
(nothing specified about the kind of drivers or precision) build fine since
the second condition is fulfilled.

By the way, there has been quite a substantial move from PLplot-5.1.0 to
PLplot-5.2.0.  There have been something like 3000 downloads so far.
Apparently, relatively few of those users have run into the above problem
(presumably because it is rare to demand static drivers and double precision
at the same time).  Nevertheless, once the fix for the problem has been
thoroughly tested on a wide variety of platforms it will become part of
our next release of PLplot.
