Editing Octave for Red Hat Linux systems

For RedHat-based distributions like RedHat, CentOS, Fedora, Scientific Linux, ...

=== Generic RedHat ===

Tested Fedora 33, but not completely.

  dnf install libtool make automake autoconf gcc gcc-devel \
  g++ g++-devel gcc-fortran gawk gperf less ncurses

Tested Fedora 20, but not completely.

  yum install gcc gcc-c++ kernel-devel make mercurial libtool libtool-ltdl-devel libtool-ltdl autoconf cmake lapack-devel \
  lapack pcre-devel readline-devel readline fftw-devel glpk-devel suitesparse suitesparse-devel gnuplot libcurl-devel zlib-devel \
  flex texlive gperf fltk-devel qhull-devel hdf5-devel gl2ps-devel qrupdate-devel arpack-devel qscintilla-devel llvm-devel qt-devel \
  bison ghostscript-devel librsvg2-tools icoutils texlive-metapost

=== CentOS ===

Enable use of [https://fedoraproject.org/wiki/EPEL Extra Packages for Enterprise Linux (EPEL)] AND THEN install octave dependencies development packages:

    yum -y install yum-utils
    yum-builddep -y octave
    yum -y install qt-devel mercurial gcc-c++ lapack-devel libtool
    yum -y install epstool transfig pstoedit qscintilla-devel

The arpack-devel package distributed with CentOS 7 (arpack-devel-3.1.3-2.el7.x86_64) seems a bit old, as routine "seupdate" seems not recognized during
the "configure" step. This can be solved by installing arpack from github:
    git clone git@github.com:opencollab/arpack-ng.git
    cd arpack-ng
    ./bootstrap
    ./configure --prefix="some local prefix"
    make; make install

Current release as of Aug. 20th 2018 seems to compile OK with CentOS blas-devel

===== Prepare installation of Octave =====

The remaining steps do not need to be done as root, except for
possibly the final installation step.  I recommend you create an
installation directory like /usr/local/octave/VERSION so that it is
easy to uninstall a given version simply by removing a directory tree.
Then to use the installed version, put /usr/local/octave/VERSION/bin
in your PATH.  If you create the /usr/local/octave/VERSION directory
with appropriate permissions, it is not necessary to be root to
install Octave.  For example,

    mkdir -p /usr/local/octave/dev
    chown jwe.jwe /usr/local/octave/dev

create src and build directories:

    mkdir src build

===== Compiling Octave from source =====

Check out a copy of the octave sources in the src directory

    cd src
    hg clone http://hg.savannah.gnu.org/hgweb/octave

* bootstrap the build system

    cd octave
    ./bootstrap

* build Octave in the build directory.  choose whatever prefix is appropriate for your system.  the -jN option builds in parallel

    cd ../../build
    ../src/octave/configure --prefix=/usr/local/octave/dev
    make -j6 all

* Run the test suite

    make check

* If everything looks OK (a few failures are probably normal for the development version) install it

    make install

==== Installing using snap ====

https://snapcraft.io/install/octave/centos - Easiest way to install.

* Enable snapd. Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:

    sudo yum install epel-release

* Snap can now be installed as follows:

    sudo yum install snapd

* Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:

    sudo systemctl enable --now snapd.socket

* To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:

    sudo ln -s /var/lib/snapd/snap /snap

Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.

* Install octave. To install octave, simply use the following command:

    sudo snap install octave
