[vtkusers] vktFLTK build errors (Mac OS X)

[Marius S Giurgi]

Has anyone successfully compiled and use the vtkFLTK 
(http://vtkfltk.sourceforge.net)?

I was trying to build the vtkFLTK bridge library on Mac OS X (10.3.7) 
unsuccessfully, with the following errors:

I have the following installed:
cmake version 2.0.5
fltk version 1.1.6
vtk version CVS nightly build

I'm not sure whether this is a mac os x problem or not. Could someone 
please give me an idea of how to fix this?
Also, what about the warnings (some classes being deprecated). Is this 
because I use the latest (CVS) vtk version?

thanks,
marius
