Hi Robert,

I inferred a CMakeLists.txt from the wiki page


================ CMakeLists.txt for the plugin

PROJECT(VisItReaderGFDL)

cmake_minimum_required(VERSION 2.8)

FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})

SET(SOURCES
 avtCM24FileFormat.C
 )

ADD_VISIT_PLUGIN_READER(VisItReaderGFDL "1.0"
  VISIT_READER_NAME "avtCM24FileFormat"
  VISIT_READER_TYPE "MTSD"
  VISIT_READER_FILE_PATTERN "nc"
  SERVER_SOURCES ${SOURCES}
  )

TARGET_LINK_LIBRARIES(VisItReaderGFDL vtkVisItAVTAlgorithms)
============================

I then placed the .C and .h files in the same directory
sms:/local/home/build/paraview-plugin> ls -alF gfdl-paraview-loader
total 112
drwxr-xr-x 2 sms t  4096 Apr 11 14:53 ./
drwxr-xr-x 5 sms t  4096 Apr 11 14:20 ../
-rw-r--r-- 1 sms t 87958 Apr 11 12:51 avtCM24FileFormat.C
-rw-r--r-- 1 sms t  7311 Apr 11 14:25 avtCM24FileFormat.h
-rw-r--r-- 1 sms t   404 Apr 11 13:02 CMakeLists.txt


Then in the build directory, I did a ccmake and entered the right text for
ParaView_DIR variable and I got this after configure/generate/make

sms:/local/home/build/paraview-plugin/gfdl-paraview-loader-build> ls -alF

-rw-r--r-- 1 sms t  4169 Apr 11 14:24 vtkVisItReaderGFDLSM.xml


however, loading the plugin using plugin manager gui resulted in an error

Cannot load library
/local/home/build/paraview-plugin/gfdl-paraview-loader-build/libVisItReaderGFDL.so:
(/local/home/build/paraview-plugin/gfdl-paraview-loader-build/libVisItReaderGFDL.so:
undefined symbol: _ZTI17avtCM24FileFormat)

then from your plugin wiki page, I added the following line into my
avtCM24FileFormat.h file

vtkCxxRevisionMacro(VisItReaderGFDL, "$Revision$");

but when I compile, I get

sms:/local/home/build/paraview-plugin/gfdl-paraview-loader-build> make

and actually, my plugin code also depend on both netcdf and hdf5 library
which is specified in my VisIt xml file

sms:/local/home/build/paraview-plugin/gfdl-visit-load> cat CM24.xml
<?xml version="1.0"?>
  <Plugin name="CM24" type="database" label="NetCDF CM2.4" version="1.0"

  </Plugin>

how do I go about adding the appropriate netcdf and hdf5 libraries into the
plugin CMakeLists.txt file?

any help is much appreciated.

thank you
