Most of the dependencies given in this section can be very conveniently installed on many [[Octave for GNU/Linux|GNU/Linux]] systems.  Please read the respective wiki page for your distribution on the [[Octave for GNU/Linux]] page.
  
{| class"wikitable"
+
On [[Octave for Microsoft Windows|MS Windows]] and [[Octave for macOS|macOS]] systems the generic Octave build process described on this page needs some more effort to fulfill the described build dependencies.  Please read [[Octave for Microsoft Windows]] and [[Octave for macOS]] for information how to build Octave for the respective systems.

== Tweaks ==
 +
 +
=== 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}}.
 +
 +

This article provides general information about building GNU Octave from source. If you just want to install Octave, see Category:Installation.

General steps[edit]

  1. Install all build dependencies (see below).
  2. Getting the Octave sources ...
    • ... from the development repository (requires also Mercurial)
hg clone https://www.octave.org/hg/octave && \
cd octave                                  && \
./bootstrap
  • ... from a release
wget https://ftpmirror.gnu.org/octave/octave-5.1.0.tar.gz && \
tar -xzf octave-5.1.0.tar.gz                               && \
cd octave-5.1.0
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. Please read the respective wiki page for your distribution on the Octave for GNU/Linux page.

On MS Windows and macOS systems the generic Octave build process described on this page needs some more effort to fulfill the described build dependencies. Please read Octave for Microsoft Windows and Octave for macOS for information how to build Octave for the respective systems.

Dependencies marked with green background are required for building Octave. All other tools and libraries are recommended/optional, but very useful features (like the GUI, plotting, etc.) are likely to be disabled.

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.

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.
