=== Install Octave in home directory === | |||
To install multiple versions of GNU Octave on one system, it is recommended to use the <code>--prefix</code> option of the <code>configure</code> script. With this option one can determine a custom installation directory, preferably within your user's home directory, to avoid elevated installation privileges. One does not "clutter" the system by running <code>sudo make install</code> and the custom build Octave can coexist with, for example, your Linux distribution installation of Octave. | |||
In order to start the custom build of Octave almost as convenient as the Linux distribution installation of Octave, one can create an alias within {{Path|.bashrc}}: | |||
echo "alias myoctave='$HOME/my_octave/bin/octave'" >> ~/.bashrc | |||
Then update your {{Path|.bashrc}} without doing logout and login: | |||
source $HOME/.bashrc | |||
If you simply enter <code>octave</code>, you'll start your Linux distribution installation of Octave. But when you enter <code>myoctave</code>, you'll start your custom build of Octave inside your home directory. | |||
=== Uninstall === | |||
# If you still have the {{Path|.build}} folder, just run <code>make uninstall</code> from it. | |||
# Just delete the install folder, e.g. <code>rm -rf $HOME/my_octave</code>. | |||
In any case, don't forget to remove any created ''alias'' entries in {{Path|~/.bashrc}}. | |||
=== Large array support === | |||
