Updating to latest version
=========================================

This page describes how to update the  **DoGPack**
code to the latest version. 
The updating process will only work if you already have **DoGPack**
properly installed (see `installation page <install.html>`_).
If you encounter any difficulties in the update process, please 
`send e-mail <dog-users@yahoogroups.com>`_
to the `discussion group <http://tech.groups.yahoo.com/group/dog-users/>`_.



Updating via Git 
-----------------------

Move into the main **DoGPack** directory:
::
 
 $ cd $DOGPACK

Pull the latest revisions from the **DoGPack** git repository:
::
 
 $ git pull



Safely recompiling code
----------------------------

If the update has significant changes, especially those that
affect the library files, the best course of action is to 
recompile the entire **DoGPack** code. Do this by first
moving into the desired application directory, e.g.:
::
 
 $ cd $DOGPACK/apps/2d/euler/radial_shock

Then do a full removal of all obect files through the following command:
::
 
 $ make cleanallo


Finally, recompile the code:
::
 
 $ make
