These are names of subroutines in the netCDF Fortran-77 version 2
interface.  They are compiled and included in the netCDF library when
the library is built with the Fortran interface.  So first check that
you didn't omit the Fortran interface (which you could have done by
specifying the environment variable FC='' before invoking the
configure script, for example).

If the Fortran-77 interface was built, then invoking "make test"
should have included the tests of the subroutines in this interface,
and should have produced output something like this (after the tests
of the C interface):

  Making `test' in directory /scratch/russ/builds/buddy-opt/src/fortran

  + /opt/SUNWspro/bin/f77 -c -O -w ftest.F 
  /tmp/fpp.26521.0.f:

if the tests ran successfully.  If they did, then that shows that the
libnetcdf.a library file does include the Fortran subroutines.  

If you installed it, perhaps you have just neglected to tell the
Fortran compiler where it's installed so it can link gennet.  For
example, if you installed the library in

  /usr/local/netcdf/lib/libnetcdf.a

then you should compile gennet.f using 

  -L /local/netcdf/lib -lnetcdf

flags, as in:

  f77 gennet.f -o gennet -L /local/netcdf/lib -lnetcdf

I hope this helps.
