[vtkusers] VTK 6.0 static New() function returns NULL

[David Cole]

This has come up several times recently, for example, last month in 
this thread:

  http://www.vtk.org/pipermail/vtkusers/2013-March/127811.html

(Follow that whole thread through to see some suggestions about how to 
make this work for a non-CMake based project right now.)

Or take a look at this commit in VTK/Examples, that shows how to build 
an Xcode project against VTK 6:

   
https://github.com/Kitware/VTK/commit/9385718b82e6af83b7e7dcc90a937419edc6892b

Perhaps we (the VTK community) ought to consider providing a 
configured/installed header file that provides the auto init defines 
rather than stuffing them into CMake properties... Apparently, there 
are several real-world VTK clients who do not use CMake to drive their 
projects.

If the defines were in a centrally included VTK header file, then 
anybody including the header would get the defines, regardless of 
whether they use CMake to drive their build or not. Wouldn't it be 
better if that were automatic, and people didn't run into this problem? 
(i.e. -- it would be easy to turn this into a non-issue...)


Just a thought,
David C.

Hi all,

Marcus you're right and the wiki helps.... To understand; my problem 
now is
that I did not use CMAKE in our project, it is a Qt project...

So, how to have the factory properly set with implemented methods?
Do I have to use cmake at all cost?
Isn't it possible to to have the those methods implemented when one 
compile
and link the release?

Thank your for your help,
Sebastien.
