[Paraview] building paraview 3.98.1 with the pgi compiler (13.3.0-12.5.0)

Thu Jul 18 15:08:41 EDT 2013

So I misread the header that parses
VTK_CONST_REVERSE_ITERATOR_COMPARISON. If
VTK_CONST_REVERSE_ITERATOR_COMPARISON is set, we are stating that
compiler
DOES support const_reverse_iterator comparison, if it is not set the
compiler doesn't.

I expect due to cross compilation the
VTK_CONST_REVERSE_ITERATOR_COMPARISON is being defined in your case,
while you actually want it not defined.

VTK can be used with compilers like pgi that have a broken
const_reverse_iterator implementation.

My question is whether VTK/ParaView somehow accommodates this and has logic to get around using this REVERSE_ITERATOR_COMPARISON when the variable VTK_CONST_REVERSE_ITERATOR_COMPARISON is not defined. I did try and undefined VTK_CONST_REVERSE_ITERATOR_COMPARISON, but the same error remains. I checked the file VTK/Rendering/Context2D/vtkAbstractContextItem.cxx where the error is raised and did not find any logic to handle the case where VTK_CONST_REVERSE_ITERATOR_COMPARISON is not defined. Does this mean ParaView cannot be built using a compiler that does not support REVERSE_ITERATOR_COMPARISON?

Looks like this VTK_CONST_REVERSE_ITERATOR_COMPARISON, although defined in the vtkConfigure.h, is not honored by the pgi compiler on Titan. Any suggestions/workarounds to get around this issue?
