Hi Bob! Unfortunately, we haven't packaged a binary version of the netCDF libraries for MacBooks or MacPros yet, partly because we are still trying to get our Absoft Fortran compiler working. However, if you have gfortran already installed or you don't need a Fortran interface, the latest source distribution should build out of the box with a simple configure, make check, and make install sequence, as described here: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/Quick-Instructions-for-Installing-NetCDF-on-Unix.html --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: SYD-350857 Department: Support netCDF Priority: Normal Status: Closed
