Tim, I'm stumped. All I can recommend at this point is that you try building and installing netCDF from the current daily snapshot release and try linking against that, making sure there are no older versions of shared libraries installed that will be used in preference to the newly installed netCDF library. The daily snapshot is available here: ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-daily.tar.gz The reason the daily snapshot may work better is explained here: http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html#gfortran_43 I've also handed this off to my colleague Ed, who may see something I'm not seeing with fresh eyes on the problem. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: FTD-335729 Department: Support netCDF Priority: Normal Status: Open
