Compiling and installing in the Anaconda environment
--------------------------------------------------------

.. NOTE:: If you are using a prebuilt Virtual Computer, you can skip this page.

This is the second of four final steps required to get the CODAS
software installed on the computer built using earlier sections
of this documentation.  This page is specific to an Anaconda environment.

This assumes you have (from the previous section)
 (1) code in ``/home/adcpcode/programs``
 (2) your anaconda directory is ``~/anaconda``

This was written for an OSX example, but would work
just as well with Linux.  

----


.. NOTE:: You must compile the ``codas3`` library and binaries before
          you compile/install the rest of the Python code.



.. NOTE:: If your Anaconda environment has python and pyhton3, make
          sure you are running Python3 for all CODAS operations.



Test your Python environment::

     type:
             python --version

     you should see:

             Python 3.6.3 :: Anaconda custom (64-bit)            
          
     (or a Python version of 3.7)

          
Compile and install ``codas3`` first::

    cd codas3
    ./waf configure --python_env
    ./waf build
    ./waf install
    cd ..


.. note:: If the `build` stage gives an error on OSX, try re-doing the
   `configure` stage with an additional specification::

      ./waf configure AR=/usr/bin/ar --python_env
      ./waf build
      ./waf install

The ``--python_env`` option above will make the installation be
in the Anaconda environment instead of the default ``/usr/local``.
Either will work, but keeping everything together makes it
easier to keep track of what you have installed, and to
delete it all if you want to make a fresh start some time.


At this stage, you can compile the CODAS Python extension code, in
``pycurrents``, which includes the Python CODAS reader and various
tools we use for Python-based CODAS processing::

    cd pycurrents
    python ./runsetup.py
    cd ..

Last, install ``uhdas`` and ``onship``::

    cd uhdas
    python runsetup.py
    cd ..

    cd onship
    python setup.py build
    python setup.py install
    cd ..


Now that you have actually compiled and installed CODAS C and Python extension
code, it is time for the next step: getting the
`non-Mercurial components <zip_codas.html>`_.
