Hello Bert,

I hope the book helped. :)

Your script is not actually linking the example with _any_ libraries, so you
should expect numerous undefined references.  You could modify your script
to link with the built VTK libraries, but it is far easier to run ccmake
e.g. in VTK/Examples/GUI/Motif (where Example1.cxx lives) and have it
generate a good Makefile.  "make Example1" will then do the trick.

I can't remember if this applies to the VTK4.0 release as well.

Good luck,
Charl
