To make NetCDF work properly, NetCDF must be built with the same compiler that you are using to build WRF. Downloading and installing NetCDF from source also enables you get the advantage of having latest version of NetCDF and seperating it from the NetCDF libraries installed from Ubuntu repository. This section follows the instructions at [CMAQ tutorial build library gcc].
NOTE: It's assumed here that you are at your $HOME directory.
NOTE: Make sure you were completed previous steps:
- Set environment variables to install NetCDF and create the installation folder.
PATH_TO_APPS=/path/to/apps/directory
NETCDF=$PATH_TO_APPS/NETCDF
export LD_LIBRARY_PATH=$NETCDF/lib:$LD_LIBRARY_PATH
export PATH=$NETCDF/bin:$PATH
mkdir -p $NETCDF- Download netCDF-C library, untar and change directory into extracted dir.
wget ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-c-4.7.0.tar.gz
tar -xzvf netcdf-c-4.7.0.tar.gz
cd netcdf-c-4.7.0- Run the configure command
./configure --prefix=$NETCDF --disable-netcdf-4 --disable-dapIf the command worked correctly, you should get the following result.

+-------------------------------------------------------------+
| Congratulations! You have successfully installed netCDF! |
| |
| You can use script "nc-config" to find out the relevant |
| compiler options to build your application. Enter |
| |
| nc-config --help |
| |
| for additional information. |
| |
| CAUTION: |
| |
| If you have not already run "make check", then we strongly |
| recommend you do so. It does not take very long. |
| |
| Before using netCDF to store important data, test your |
| build with "make check". |
| |
| NetCDF is tested nightly on many platforms at Unidata |
| but your platform is probably different in some ways. |
| |
| If any tests fail, please see the netCDF web site: |

| NetCDF is developed and maintained at the Unidata Program |
| Center. Unidata provides a broad array of data and software |
| tools for use in geoscience education and research. |

- Download netCDF-Fortran library, untar the netCDF-Fortran tar.gz file and change directory into extracted dir.
wget ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-fortran-4.4.5.tar.gz
tar -xzvf netcdf-fortran-4.4.5.tar.gz
cd netcdf-fortran-4.4.5- Run configure and make check commands. Exports are required to make NdtCDF-Fortran to be able to find NetCDF-C.
