Even before that (in versions 4.1.1 through 4.1.3) the Fortran libraries were installed in a separate library file, which required Fortran builds to link with the Fortran library using an additional library specification, as in something like (depending on where your libraries were installed) gfortran ... -L/usr/local/lib -lnetcdff -lnetcdf to search in both the Fortran netCDF library and the C netCDF library. You also need to indicate where the Fortran-90 module, usually something like "netcdf.mod", was installed, with a "-I" or "-M" flag, such as gfortran ... -I/usr/include ... Finally, I have seen the kind of error you are seeing on MacOS X 10.7 (Lion) systems, when ifort is the Fortran compiler. In that case, setting the following environment variable is required for successful linking: lt_cv_ld_force_load=no when running "configure" to build the netCDF libraries, as described here: http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html#intel-fortran-macosx --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: RTU-667260 Department: Support netCDF Priority: Normal Status: Closed
