[vtk-developers] Error building Python wrappings of member functions that return vtkVector2i/f with VS2010

[David Gobbi]

The VTK dashboard tests the VTK 5.8 branch on VS2010 with
Python every night and has never shown this issue.  On your
system, the problem might be an incorrectly generated hierarchy file
Filtering/vtkRenderingHierarchy.txt, can you open this file in an
editor on both your Windows build and OS X build to see if the
vtkVector2i entries are the same in each?

Also, just to confirm, do your OS X build and VS2010 build use git
checkouts from the same date?  Because the vtkVector header file was
recently moved into the VTK/Common directory, and that is what most
likely triggerred this issue.
