Editing Octave for GNU/Linux

The recommended way for installing Octave and Octave-Forge packages on GNU/Linux systems 
is via each distribution package installation system.

More detailed instructions follow.

=Debian and Debian-based (such as Ubuntu)=

: ''Main article: [[Octave for Debian systems]]''

Simply install Octave from your distribution repository

 apt install octave

For old versions of Ubuntu that only supply old versions of Octave, consider using Octave's PPA. For more details, see the [[Debian]] specific instructions page.

There are also Debian packages for each of the Octave Forge packages, named {{codeline|octave-<pkg>}}, for example {{codeline|octave-image}} and {{codeline|octave-statistics}} for the image processing and statistics package respectively. A complete list of them can be found with the command

 apt search octave-forge

=Fedora=

: ''Main article: [[Octave for Red Hat Linux systems]]''

The packages can be installed using the dnf command, they are:

*octave
*octave-devel

{{Codeline|octave-devel}} contains the octave headers and {{Path|mkoctfile}} script and is really only needed by users who are developing code that is to be dynamically linked to octave. {{Codeline|octave}} can be installed with the command:

    # dnf install octave

=Gentoo=

Octave is available through Gentoo's package management system, Portage:

    # emerge --sync
Add USE flag 'curl' into your <code>/etc/portage/package.use</code> file to enable remote Octave-Forge packages fetching
 sci-mathematics/octave curl
and emerge Octave
    # emerge octave
Since Octave ver. > 3.4.0 is able to fetch Octave-Forge packages from remote repository, packages ''octave-forge'' or ''g-octave'' are no more needed.

Before installing any Octave-Forge package, in Octave command prompt you must type
 pkg -forge list
and then install your favourite packages. Typically, you have to start with 
 pkg install -forge general

=Red Hat Enterprise/CentOS=

: ''Main article: [[Octave for Red Hat Linux systems]]''

Octave is available for Red Hat Enterprise Linux distributions through the [https://fedoraproject.org/wiki/EPEL EPEL] repository. This section applies to CentOS, Scientific Linux, and other Red Hat Enterprise rebuild distributions as well.

'''Method 1 - the quick way:'''

    yum install epel-release
    yum install octave

'''Method 2 - if the above does not work:'''

First, follow [https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F these instructions] to set up your system to install packages from EPEL. For example,

    # wget <nowiki>http://url/to/latest/epel-release-6-7.noarch.rpm</nowiki>
    # yum localinstall epel-release-6-7.noarch.rpm

Once the EPEL repository has been enabled, you can follow the rest of the [[#Fedora|instructions for Fedora]] to install Octave using yum.

Note that EPEL intentionally does not follow new releases as closely as other distributions. Consequently, the version of Octave provided by EPEL may be several months or years out of date. There are plans for the Octave maintainers to provide support and binary RPMs for enterprise GNU/Linux distributions; contact the [mailto:maintainers@octave.org maintainers mailing list] for more information.

=SUSE Linux and openSUSE=

: ''Main article: [[Octave for openSUSE]]''

Binary packages for Octave are provided by all versions of openSUSE. It can be installed by command:

 zypper in octave

Latest stable version of Octave and Octave-Forge are available on Science repository. For details see [[openSUSE]] specific wiki page.

=Arch Linux=

: ''Main article: [[Octave for Arch Linux]]''

Updated Octave's version is in the extra repository. It can be installed by typing:

    # pacman -S octave

=Homebrew on Linux=
<div id="Linuxbrew" />

Octave is provided by the [https://brew.sh/ Homebrew] package manager, which is a cross-distribution packaging system. "Homebrew on Linux" was formerly a fork known as Linuxbrew. It is possible to install the current release of Octave or the development version and any needed dependencies within your home directory. This is particularly useful if you have an older GNU/Linux distribution or if you do not have root access.

Homebrew can be installed with the command:

    sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

It can be added to your shell environment and future login environments with:

    test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)
    test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
    test -r ~/.bash_profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile
    echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile

Once set up, Octave can be installed with the command:

    brew install octave

=Docker=

Octave is available as a Docker container. This can be used to easily run Octave in a well-defined, minimal GNU/Linux container. It can be used as a standard interactive Octave shell or to run scripts, but it may be mostly of interest to developers for use in automated build, test, or CI environments.

    docker pull mtmiller/octave
    docker run mtmiller/octave octave --version

The image is hosted at [https://hub.docker.com/r/mtmiller/octave mtmiller/octave on Docker Hub].
