Hi all,

I've been experimenting with PLplot for awhile.  Mainly I use PDL, and
thus interactive plotting with the xwin driver and the
PDL::Graphics::PLplot module.  But until now I was not able to get over
one hurdle: that whenever I covered up the window, the contents would
disappear until the next plotting command was issued.  Just last week I
was searching the email lists and found that setting the HAVE_PTHREAD
option to cmake resolves this, in quite a satisfactory way.  However, I
usually just install PLplot from my distro's package manager, especially
on a new machine, because of the considerable dependencies.

Is there any (good) reason that pthreads is not enabled by default, and
thus enabled in the version downloaded from each distribution's
repository?  I don't know how that would work for packaging, how often
pthreads are installed by default, or if that would generate a huge
dependency, but it seems so convenient...

cheers,
Derek
