[vtkusers] Undiefined virtual table.

[Michael Bonner]

Hello vtk-users

I have developed an vtk app on a pc platform using the pre-compiled vtk 
binaries. I am attempting to port the app to
some compaqs running Tr64 unix 5.1, and I am using the CXX compiler. I have 
made vtk 4.0 and everything seemed compile fine. When I make my app  I get 
the included linking error. I do not have much experience with make and I 
really have no idea what could be wrong. In my code I used vtkHedgeHog and 
vtkClipPolyData; these are the classes that extend the classes with the 
undefined virtual tables. As expected, the linking errors are gone if I 
remove their use from the code. I do not know what is causing this problem, 
I suspect it involves how I am making vtk and/or how I am making my app (ie 
my Makefile).

Any help or suggestions would be greatly appreciated.
