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

[Hong Yi]

I did an experiment to use pgi compiler to compile a simple program test.cpp like the following:
-----------------------
#include <vector>
int main()
{
  std::vector<int> test;
  std::vector<int>::const_reverse_iterator it = test.rbegin();
  it != test.rend();
  return 0;
}
-------------------------
by running "pgCC test.cpp -o test" then I got the same error below:
--------------------------
"test.cpp", line 6: error: no operator "!=" matches these operands
            operand types are: std::reverse_iterator<const int *> !=
                      std::reverse_iterator<int *>
    it != test.rend();
       ^
--------------------------

So I think the pgi compiler included in PrgEnv-pgi/4.1.40 module I am currently using on Titan does not support REVERSE_ITERATOR_COMPARISON. 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?

Thanks,
Hong

Just a supplemental note to the previous message below: if I don't run ccmake to reconfigure and regenerate, and directly run "make" after changing the line to "#define VTK_CONST_REVERSE_ITERATOR_COMPARISON 1" the same error/issue still remains. 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?

Thanks,
Hong

Thanks, Robert. I have been working with Suzanne on this issue. The line in vtkConfigure.h is:
#define VTK_CONST_REVERSE_ITERATOR_COMPARISON

We changed it to be
#define VTK_CONST_REVERSE_ITERATOR_COMPARISON 1 but after reconfiguring and regenerating, the line changes back to the original "#define VTK_CONST_REVERSE_ITERATOR_COMPARISON"

Because of this, rebuilding ParaView on Titan with pgi compiler generates the same error.

Any further suggestions on this issue?

Thanks,
Hong

We have seen this issue with const_reverse_iterators before on older versions of gcc. What is the value of VTK_CONST_REVERSE_ITERATOR_COMPARISON in the build directory file Common/Core/vtkConfigure.h?
