The undefined reference is telling you that the netCDF entry points
nf_create__ and nf_close__ are not being found during the link.  It
appears, therefore, that you are not including a search of the netCDF
library when doing your link, or that you are using the default
LD_LIBRARY_PATH for your library search, and the netCDF library
got installed in a directory that is not in that LD_LIBRARY_PATH.

Check your LD_LIBRARY_PATH first.  If need be, explicitly include a
search of libnetcdf.a on your link line.
