Hi Kara, Please try gfortran -o simple simple_xy_wr.o -L/sw/lib/netcdf -lnetcdf or gfortran -o simple_xy_wr simple_xy_wr.o /sw/lib/netcdf/libnetcdf.a If the library is installed in the directory /sw/lib/netcdf/, then either of those should work, but let us know if they don't. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: GAW-821062 Department: Support netCDF Priority: Normal Status: Closed
