[netCDF #FHI-783210]: netcdf building and linking to gfortran

Hello Adam,

To answer in reverse order, there are flags and options you *can* set when 
building netCDF, but whether or not you *need* to depends on what you are 
trying to do.  You can find information related to building netCDF-C at 
http://www.unidata.ucar.edu/software/netcdf/docs/getting_and_building_netcdf.html.
  You can also (for netCDF-C and netCDF-Fortran) see what options are available 
via `./configure --help`.

You will need to install netCDF-C before installing netCDF-Fortran; 
netCDF-Fortran provides a fortran interface to netCDF-C, and is not a complete 
re-implementation of netCDF in Fortran.

Regarding libphypluto.a, wstats.o and the the other compilations errors you 
reference; I'm not sure what libphypluto is, or what the linker means about the 
library having being compiled in "deterministic mode".  I will note that it is 
a warning, and not an error, and so may be ignored if you determine it is safe 
to do so.  The final error you report, regarding 'main', is typical of there 
being an error in the build process but the information you provide is not 
indicative of an error, just a warning.

I'm sorry I can't provide more immediate help,

-Ward
