Dear All,

Lets see the procedure on how to install ESMF and ESMFPy package using gcc, gfotran, Ubuntu and Python.

You can read more about ESMF https://www.earthsystemcog.org/projects/esmf/

I downloaded esmf_6_3_0rp1_src.tar.gz file from here.

I used Ubuntu 14.04 LTS 64-bit OS to install the ESMF and ESMFPy package.

Login as root, sudo may not work if your target installation path would be /usr/local.

After extracted the above said package then go to that directory.

# root@Ocean:/home/tuxcoder/esmf

Copy paste the following environmental variables in your terminal.

NOTE : you have to change the source directory as per your system path. i.e. ESMF_DIR.

Then you have to provide netcdf4 include path. If you didnt install netcdf4 already then you may read my previous post here.

export ESMF_DIR=/home/tuxcoder/esmf
export ESMF_INSTALL_PREFIX=/usr/local/esmf
export ESMF_OS=Linux
export ESMF_NETCDF="local"
export ESMF_COMM=mpiuni
export ESMF_F90COMPILER=gfortran
export ESMF_CXXCOMPILER=g++
export ESMF_TESTEXHAUSTIVE=on
export ESMF_TESTSHAREDOBJ=on
export ESMF_NETCDF_INCLUDE=/usr/local/netcdf4/include
export ESMF_NETCDF_LIBS="-lnetcdf -lnetcdff"
export ESMF_NETCDF_LIBPATH=/usr/local/netcdf4/lib
export ESMF_BOPT=O3

After exported all the above environmental variables, then you can do make all followed by make install.

# make all

# make install

# make installcheck

Now we installed ESMF package in our system.

Lets install ESMFPy in our system python by pointing ESMF package by following steps.

# cd /home/tuxcoder/esmf/src/addon/ESMPy/

# python setup.py build --ESMFMKFILE=/usr/local/esmf/lib/libO3/Linux.gfortran.64.mpiuni.default/<a href="http://esmf.mk">esmf.mk</a>

# python setup.py install

Thats it! We successfully installed ESMF and ESMFPy in our gcc, gforatran, Linux based system.

To use ESMFPy, issue the following command.

tuxcoder@Ocean:~$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ESMF
>>>
