Hi, PLplot developers,

After finishing my MacPorts update. I am no longer able to build
PLplot due to a missing header file for qhull. The MacPorts update
brought with it qhull version 2010.1. Previously I had qhull version
2003.1. According to the qhull web site (http://www.qhull.org/): "A
"serious bug was found in Qhull 2003.1 . Please upgrade to 2010.1 or
apply poly.c-qh_gethash.patch.".
The problem is that the MacPorts installation of qhull 2010.1 does
NOT install the "qhull/qhull_a.h" file. Instead, it installs just
"libqhull.h". I don't know if this is a bug in the MacPorts qhull
"portfile" or if it is a bug in qhull's installation process in
general. From what I can tell of qhull's installation process (now
using cmake), it looks like libqhull.h is the only header file
installed (and even that is only in the qhull git repo, not in the
qhull-2010.1-src.tgz distribution tarball!).
I tried to replace the occurrences of qhull/qhull_a.h with
libqhull.h, but it seems that libqhull.h includes "user.h", which is
another qhull header that does not get installed.
Has anyone successfully built PLplot using qhull 2010.1?
Yes.
You really do need qhull_a.h. See
src/plgridd.c:#include <qhull/qhull_a.h>
That file is part of the tarball. Look for it in qhull-2010.1/src/. The
CMake-based build system that comes with the tarball really sucks (static
libraries only, no install). Werner (with some help from me) is putting
together an improved version of that which we plan to donate to the qhull
developers. I attach a modified qhull-2010.1/src/CMakeLists.txt that worked
for me on Linux, and I encourage you to generalize it for your own needs and
get back to us.
