Hello, I'm wondering if there is another version of libnetcdf installed on the system; this is a bug we would encounter with older versions of netCDF-C. What do you see if you run (substituting the appropriate path) $ ldd ../fortran/.libs/libnetcdff.so | grep libnetcdf This should tell us which netcdf-c library you're linking against. Once we can confirm it's the correct one, we can figure out what the next steps are.
