g-octave

Introduction

What is GNU Octave?

GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

What is Octave Forge?

Octave-Forge is a central location for the collaborative development of packages for GNU Octave.

The Octave-Forge packages contains the source for all the functions and are designed to work with the GNU Octave package system.

What is g-octave

g-octave is a tool that generates and installs ebuilds for Octave-Forge packages "on-the-fly" to Gentoo Linux, using Portage, Paludis or pkgcore. It's capable to generate ebuilds and Manifest files (if needed) for the packages, and to install them using an autogenerated overlay (named g-octave). g-octave can also handle patches to the packages automatically. The command line interface tries to be very similar to the interface of the emerge tool.

Dependencies

g-octave have some basic dependencies:

Settings

All the settings are centralized on the file /etc/g-octave.cfg. Please read the comments and change what you need. The recommendation is to keep everything as it is. :)

You can also use environment variables to configure g-octave.

--no-scm
disable the installation of the current live version of a package, if enabled on the configuration file
-f, --force
forces the recreation of the ebuilds
--force-all
forces the recreation of the overlay and of the ebuilds
--no-colors

--config
return a value from the configuration file (/etc/g-octave.cfg)
--list-raw

Usage Examples

Install the latest version of control:

# g-octave control

Install the version 0.3.1 of control:

# g-octave control-0.3.1

Upgrade to latest version available of control:

# g-octave -u control

Remove the package control:

# g-octave -C control

Get informations about the package control:

# g-octave -i control

To install the package control from the octave-forge SVN repository:

# g-octave control-9999

The options verbose, ask and pretend are passed to emerge.

How can I help?

The users can help testing and reporting bugs in our issue tracker. If you can help programming in Python you're always welcome. :)

g-octave ebuilds are available on the Git repository, or the Gentoo science overlay.

Warning

If you experienced some random errors when installing packages, please retry, using the option --force-all, and report the issue to us. If you don't want to lose all your ebuilds, you can try to use the option --force, that will re-create only the affected ebuild.
