How to run NetCDF from a C Program

In your program include the appropriate NetCDF header file:

#include <netcdf.h>

and call the appropriate NetCDF functions.

To compile and link enter:

CC pgm.c -I$NETCDF_HOME/include -L$NETCDF_HOME/lib -lnetcdf -lm -o pgm

• Replace CC with either gcc or icc depending on which compiler you want to use.
• Replace pgm.c with the name of the file containing your source code
• Replace pgm with the name of the executable to be created.
• Set NETCDF_HOME /u/local/apps/netcdf/current.

You can either set an environment variable or replace $NETCDF_HOME in the command shown above.

How to run NetCDF from a C++ Program

In your program include the appropriate NetCDF header file:

#include <netcdfcpp.h>

and call the appropriate NetCDF functions.

To compile and link enter:

CC pgm.cpp -I$NETCDF_HOME/include -L$NETCDF_HOME/lib -lnetcdf_c++ -lnetcdf -lm -o pgm

• Replace CC with either g++ or icpc depending on which compiler you want to use.
• Replace pgm.cpp with the name of the file containing your source code
• Replace pgm with the name of the executable to be created.
• Set NETCDF_HOME /u/local/apps/netcdf/current.

You can either set an environment variable or replace $NETCDF_HOME in the command shown above.

How to run NetCDF from a Fortran 77 Program

In your program include the appropriate NetCDF header file

include 'netcdf.inc'

and call the appropriate NetCDF functions.

To compile and link enter:

ifort pgm.f -I$NETCDF_HOME/include -L$NETCDF_HOME/lib -lnetcdf -o pgm

• Replace pgm.f with the name of the file containing your source code
• Replace pgm with the name of the executable to be created.
• Set NETCDF_HOME /u/local/apps/netcdf/current

You can either set an environment variable or replace $NETCDF_HOME in the command shown above.

How to run NetCDF from a Fortran 90 Program

In your program include the appropriate NetCDF module

use netcdf

and call the appropriate NetCDF functions.

To compile and link enter:

ifort pgm.f90 -I$NETCDF_HOME/include -L$NETCDF_HOME/lib -lnetcdf -o pgm

• Replace pgm.f90 with the name of the file containing your source code.
• Replace pgm with the name of the executable to be created.
• Set NETCDF_HOME /u/local/apps/netcdf/current

You can either set an environment variable or replace $NETCDF_HOME in the command shown above.
