Dear PLplot developers,
We are currently applying the patch attached to this message when
building the plplot package for Debian. It is authored by Nicolas
Boulenguez and is intended to install a convenience GNAT project for the
Ada binding, better fitting the current Ada standard in Debian. According
to Nicolas, “It is more and more common to build Ada sources with
gprbuild.”
You might be interested to integrate this patch to the PLplot sources.
Best,
Rafael Laboissière
