[Paraview] Error in paraview-generated code compiling paraview reader

[Randy Hudson]

I'm trying to compile a reader I've written for ParaView 1.8.2, and am getting an error in a source file created by ParaView's vtkWrapClientServer.  

I modeled CMakeLists.txt on that of <paraview_source>/Examples/PVLocal.  I derive my reader from vtkSource.  I based the XML files on what I read in the ParaView manual and on the .in files in <paraview_source>/Examples/PVLocal.

Below, I've included the compiler error message, the piece of the paraview-generated source that's causing the error, CMakeLists.txt, the beginning lines from the header file of my reader, and the interface and server manager XML.in files.

Can someone suggest a solution?

Thanks.

Randy Hudson.



Here's the error message:
-------------------------
ParaViewTest/MY_PVLocalBuild/vtkFlashHDF5ReaderClientServer.cxx: In

   vtkObjectBase*, const char*, const vtkClientServerStream&, 
   vtkClientServerStream&)':

Here are a few lines of the paraview-generated source (the last line is the one in error):
