Hi Andy, Well, I managed to get it compiled and working by linking against NetCDF 4.1.1. However, I think it makes sense to remain consistent with the NetCDF version that ParaView uses, which is what I've done and I've got that working now as well. I've not had any issues with respect to MPI so far, but I've still to finish testing. If I find any issues, I'll be sure to repost! Thanks for your help. Adriano

Hi Adriano, I wrote the vtkNetCDFCAMReader and I'm using the C++ API to NetCDF in that reader. The NcVar::name() method is used in that code. Instead of using the standard netcdf c++ header file you can include vtk_netcdfcpp.h instead. A couple of finer points that may or may not affect you: 1) There may be some issue with including mpi.h and having the netcdf header files rename some of the mpi constants. 2) The default netcdf error condition (e.g. trying to access a variable that doesn't exist using get_var() ) is to call exit. You can do something like "NcError ncError(NcError::verbose_nonfatal);" to turn this behavior off while ncError is in scope.

The call that is giving me issues is the NcVar function call, name(), which returns a NcToken (const char *). The issue is that the call now returns a NULL pointer regardless of dataset, which is wrong. To be clear: (1) I have compiled my plugin with the same, static netcdf libraries consistently between both versions of ParaView. (2) The reader code has not changed between both versions of ParaView. (3) All variables exist in the NetCDF files and the data files themselves have not changed between both versions of ParaView. (4) By removing the NcVar var->name() call in the code and hard-coding a variable name that exists in the file (e.g. const char* = "pressure"), the reader works i.e. it detects the variable, loads it in and displays it correctly. Item 4 is what leads me to believe there is now some sort of conflict occuring between the old (PV3.6.2) and new (3.10.1) versions of ParaView. I know there is support for specific NetCDF files in ParaView already. If possible, I'd like to try and compile my plugin against the NetCDF libraries used for those readers. Can I do this? In the meantime, I'm going to try downloading and compiling against the latest NetCDF libraries to see if it resolves the issue.
