Hi Simon,

You do not need to modify the avt file or add the revision macro as that is
not the problem you are currently facing. I would try reverting your avt
file to its original content, adding all the files listed in the Files
components="M" xml block to your SOURCES list, and adding the plugin build
folder to your LD_LIBRARY_PATH.

Also would you be able to send me the contents of the vtkVisItReaderGFDL.cxx
from your build directory and I will confirm the automatic wrapping is
working properly.
