Hola Gang,
I'm attempting to get PV 4.4.0 builds of Paraview
against Intel 14 and 15 on our HPC systems. One item that
some users have asked us for was the Cosmotools integration.
This ultimately needs the Qhull library to be built. Builds
against GCC 4.8.2 went through without a hitch. However the
Intel builds all failed with an odd cryptic syntax error
message that I do not fully comprehend (sorry I'm still
stuck in Fortranistan).

From what little I understand of C and C++, I believe that
"templates" are a C++ construct. I'm thinking the Intel
compiler is attempting to digest the above as "straight-up
C" and failing.
The error messages put the blame on
QHULL_SRC_ROOT/src/libqhull/qhull_a.h around line 105
I then decided to snoop on github.com for another qhull
repo. I found one
at
https://github.com/qhull/qhull
From which I believe the "https://github.com/mathstuf/qhull
next branch" repo that Paraview wants to use was forked from.
Point being that the mainline non-forked Qhull has something
different in the preprocessor conditional surrounding the
above offensive line of source:
#if defined(__cplusplus) && defined(__INTEL_COMPILER) &&
!defined(QHULL_OS_WIN)
while the mathstuf/qhull repo DOES NOT have the above
"defined(__cplusplus)" preproc conditional.
I tested to see if the addition would at least allow the
'mathstuf/qhull next branch' source to properly build with
Intel 14 and 15. It got about to 36% and then failed with
the error message:
In file included from
/tmp/conega/qhull_SRC/src/libqhullcpp/QhullIterator.h(13),
from /tmp/conega/qhull_SRC/src/libqhullcpp/Coordinates.h(13),
from /tmp/conega/qhull_SRC/src/libqhullcpp/Coordinates.cpp(11):
/tmp/conega/qhull_SRC/src/libqhull/qhull_a.h(106): error:
this declaration may not have extern "C" linkage
template <typename T>
^
So at least the conditional helped a bit for what I believe
is the "straight up C" part of the build.
I'll CC the author of the fork Ben Boeckel about this.
