- This article provides general information about building GNU Octave from source (on Unix-like systems).
- If you just want to install GNU Octave, see Category:Installation.
- For MS Windows, read Building on Microsoft Windows and Windows Installer.
- For macOS, read Octave for macOS.
General steps[edit]
- Install all build dependencies (see below).
- 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-9.2.0.tar.gz && \ tar -xzf octave-9.2.0.tar.gz && \ cd octave-9.2.0
- 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.
For a quick way to install the required dependencies, see:
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]
- If you still have the .build folder, just run
make uninstallfrom it. - 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]

Footnotes[edit]
- ↑
--prefixdetermines the installation location, see the Tweaks section for details. For more information about configuration options, type./../configure --help. - ↑ Depending on your system and processor count, use a larger number of parallel jobs, e.g.
-j8.
