[vtkusers] Re: compiling errors with vtk32

[Jean_Luc_Bordessoule at veritasdgc.co.uk]

Hi zhangzhijun,

I had a similar problem.
The problem was the inclusion of BOTH 'iostream.h' and 'iostream'.
In Vtk, these files are included by 'vtkSystemIncludes.h' :

/* first include the local configuration for this machine */
#include "vtkConfigure.h"
....
// Handle changes for ANSI C++
---------------------------------------------
#ifdef VTK_USE_ANSI_STDLIB
#include <iostream>
.....
// otherwise, non-ANSI
-----------------------------------------------------
#else
#include <iostream.h>
......

In  "vtkConfigure.h"  ,  VTK_USE_ANSI_STDLIB can be defined or undefined.

So the problem becomes the definition of 'VTK_USE_ANSI_STDLIB'
The value of VTK_USE_ANSI_STDLIB is stored in 'vtkConfigure.h' after
running 'CMakeSetup.exe'

On my machine,  VTK_USE_ANSI_STDLIB could be defined / undefined in 3
places:
   D:\Vtk40\include\Vtk\vtkConfigure.h
   D:\Vtk40\lib\vtkConfigure.h
   In Visual C++ : Project / Settings ... / C++ /  Preprocessor /
   Preprocessor Definitions .

So make sure: how VTK_USE_ANSI_STDLIB is defined
   In Visual C++ : Project / Settings ... / C++ /  Preprocessor /
   Preprocessor Definitions .
   In Visual C++ : check the library path  ( 'Tools \ Options \ Directories
   \ Library Files ' ) and make sure the correct 'vtkConfigure.h' is
   included.
