The netCDF-4 library includes support for the netCDF-3 API and formats. If you want to build only the netCDF-3 library without netCDF-4, the instructions are here: http://www.unidata.ucar.edu/software/netcdf/docs/build_classic.html and then for Fortran, follow these instructions: http://www.unidata.ucar.edu/netcdf/docs/netcdf-fortran-install.html If you still get errors, please send us the output from running configure and from running "make check". Sometimes the "config.log" file is also helpful. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: MGZ-739143 Department: Support netCDF Priority: High Status: Closed
