Install icclim 4.2 and under (outdated version)
===============================================

For a version before 5.0.0, to run icclim you first need to compile our C library.

The last version where this was needed is `4.2.20 <https://github.com/cerfacs-globc/icclim/tree/4.2.20>`_

#. Compile the C code:
    - `gcc -fPIC -g -c -Wall ./icclim/libC.c -o ./icclim/libC.o`
    - `gcc -shared -o ./icclim/libC.so ./icclim/libC.o`

#. Install icclim: `python setup.py install --user`
