Installing in your home directory is a method to install GNU Octave next to your repository installation at the same time. This works with every Linux distribution and is especially for old Ubuntu LTS versions very useful!
+
=== Install Octave in home directory ===
  
One advantage is that you do not clutter your system by running ''sudo make install''.
+
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.
Another advantage is that you can keep your Octave installation that is provided by your distribution.
 
  
=== Create a smart .bashrc entry ===
+
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 octave38='~/.octave38/bin/octave'" >> ~/.bashrc
+
  echo "alias myoctave='$HOME/my_octave/bin/octave'" >> ~/.bashrc
. ~/.bashrc # this will update your bashrc without doing logout and login!
 
  
If you simply enter ''octave'', you'll start your repository installation provided by your distribution. But when you enter ''octave38'', you'll start your new snappy octave version installed to your home directory.
+
Then update your {{Path|.bashrc}} without doing logout and login:
  
 +
source $HOME/.bashrc
  
=== Managing your own program hierarchy (optional) ===
+
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.
 
 
If you intend to compile for yourself a lot of utilities, you may use a specific "usr" hierachy into your own dir (Linux from scratch way). Go back to step 2, and configure octave as:
 
 
 
./configure --prefix=${HOME}/usr
 
 
 
The other steps (make; make install) do not change. In order to use your own hierachy, you should set a few environment variables in your .profile:
 
 
 
  # set LD_LIBRARY_PATH if not set
 
  (echo $LD_LIBRARY_PATH | grep -q lib) || export LD_LIBRARY_PATH="/usr/local/lib:$HOME/usr/lib:$HOME/usr/local/lib"
 
 
  # set PATH so it includes user's private bin if it exists
 
  if [ -d "$HOME/bin" ] ; then
 
        (echo $PATH | grep -q $HOME/usr/bin) || export PATH="$HOME/bin:$HOME/usr/bin:$HOME/usr/local/bin:$PATH"
 
  fi
 
 
 
  # set MANPATH so it includes user's private bin if it exists
 
  if [ -d "$HOME/usr/share/man" ] ; then
 
    (echo $MANPATH | grep -q $HOME/usr/share/man) || export MANPATH="$HOME/usr/local/share/man:$HOME/usr/share/man:`manpath -q`"
 
  fi
 
 
 
  if [ -d "$HOME/usr/share/info" ]; then
 
    export INFOPATH="$INFOPATH:$HOME/usr/share/info"
 
  fi
 
 
 
  if [ -d "$HOME/usr/lib/python" ]; then
 
    (echo $PYTHONPATH | grep -q $HOME/usr/lib/python) || export PYTHONPATH="$HOME/usr/local/lib/python:$HOME/usr/lib/python"
 
  fi
 
 
 
  if [ -d "$HOME/usr/lib/pkgconfig" ]; then
 
    (echo $PKG_CONFIG_PATH | grep -q $HOME/usr/lib/pkgconfig) || export PKG_CONFIG_PATH="$HOME/usr/lib/pkgconfig"
 
  fi
 
 
 
This way, most ordinary commands like "man octave", "info octave", or launching octave itself, will first explore your own hierachy.

This article provides general information about building GNU Octave from source (on Unix-like systems).

General steps[edit]

  1. Install all build dependencies (see below).
  2. Getting the Octave sources ...
(A) ... from the development repository (requires also Mercurial)
hg clone https://www.octave.org/hg/octave && \
cd octave                                  && \
./bootstrap
(B) ... from a release
wget https://ftpmirror.gnu.org/octave/octave-7.3.0.tar.gz && \
tar -xzf octave-7.3.0.tar.gz                               && \
cd octave-7.3.0
3. Configure, build, check, and install Octave
mkdir .build                            && \
cd    .build                            && \
./../configure --prefix=$HOME/my_octave && \ [1]
make -j2                                && \ [2]
make check                              && \
make install

Dependencies[edit]

Most of the dependencies given in this section can be very conveniently installed on many GNU/Linux systems.

Tweaks[edit]

Install Octave in home directory[edit]

To install multiple versions of GNU Octave on one system, it is recommended to use the --prefix option of the configure 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 sudo make install 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 .bashrc:

echo "alias myoctave='$HOME/my_octave/bin/octave'" >> ~/.bashrc

Then update your .bashrc without doing logout and login:

source $HOME/.bashrc

If you simply enter octave, you'll start your Linux distribution installation of Octave. But when you enter myoctave, you'll start your custom build of Octave inside your home directory.

Uninstall[edit]

  1. If you still have the .build folder, just run make uninstall from it.
  2. Just delete the install folder, e.g. rm -rf $HOME/my_octave.

In any case, don't forget to remove any created alias entries in ~/.bashrc.

Large array support[edit]

Main article: Enable large arrays: Build octave such that it can use arrays larger than 2Gb.

See also[edit]

Footnotes[edit]

  1. --prefix determines the installation location, see the Tweaks section for details. For more information about configuration options, type ./../configure --help.
  2. Depending on your system and processor count, use a larger number of parallel jobs, e.g. -j8.
