[vtk-developers] ruby patch to vtk-5.0.0

[David Gobbi]

Hi Seiya,

Thanks for the information about installation.  Actually I have too many 
versions of VTK on
my computer to do a "make install" of any one of them.  That is why I 
did a manual "ruby setup.rb".

Afterwards, I copied all of the vtk .rb files from 
/usr/lib/site_ruby/1.8/ to ~/VTKbin/Wrapping/Ruby
and set RUBYLIB to ~/VTKbin/Wrapping/Ruby:~/VTKbin/bin.

It would be good if "cmake" creates all the .rb files that you need in
${VTK_BINARY_DIR}/Wrapping/Ruby so that it would be possible to run the 
ruby examples
without doing a "make install" first.  In fact,  this will be necessary 
in order for VTK "make test"
to work properly with ruby, because testing has to work before install.  
Or am I missing something?

 - David
