[vtkusers] windows and linux compatibility

[imho]

Hi all,

I work on a medical image project who needs Qt, VTK and ITK.
We started developing for windows, and we've got something working but
not finalized of course. 

Now I try to make it work on linux.

I needed to take off the vtk_qt library (to test with a floating VTK
window) to finally success to compile the project, but I've still got
several problems : 

- no Qt buttons, slides or comboboxes, only the top menu
- the VTK window is all black, but the images seems to be loaded
- changing a view does a segmentation fault

So I think some things must be differents to work fine on linux, is
there some big rules to follow? On windows the heap stack has needed to
be increased, is there a similar problem on linux?

The Qt version on windows is 2.3, and on linux 3.0, maybe that could
make a problem?  

Maybe is there an opengl problem?

Thanks for any answer, I know my question isn't very accurate :s
