=========
g-Octave provides a script to run build tests for all the octave-forge
packages automatically and report issues to the `bug tracker`_.
.. _`bug tracker`: http://www.g-octave.org/trac/report/9
.. warning::
This script is not intended to be used by end-users, only developers.
Creating the environment
------------------------
We recommend the use of the script inside a chroot environment. For this
you'll need to download the latest stage3 tarball from the Gentoo mirrors
and create a basic environment::
# cd /home/user/g-octave
# tar xvjpf stage3-*.tar.bz2
Configuring the environment
---------------------------
You should copy the needed files from your Gentoo installation to the
chroot environment, to ease the configuration. ::
# cp /etc/resolv.conf /home/user/g-octave/etc
# cp /etc/make.conf /home/user/g-octave/etc
You may also need some files from ``/etc/portage``
Mounting filesystems/directories
--------------------------------
You should mount your current ``${PORTDIR}`` (e.g. ``/usr/portage``)
inside the chroot dir (the script will force the use of Portage to build
the packages)::
# mkdir /home/user/g-octave/usr/portage
# mount -o bind /usr/portage /home/user/g-octave/usr/portage
Mounting ``/proc`` and ``/dev``::
# mount -t proc none /home/user/g-octave/proc
# mount -o bind /dev /home/user/g-octave/dev
Entering the chroot environment
-------------------------------
::
# chroot /home/user/g-octave /bin/bash
# env-update
# source /etc/profile
# export PS1="(g-octave) $PS1"
Updating the packages and installing the dependencies
-----------------------------------------------------
::
# emerge -avuDN system
# USE="git" emerge -av layman
# layman -a science
# FEATURES="test" USE="sync" emerge -av g-octave
Configuring g-Octave
--------------------
You should `create an account`_ on the `g-Octave project page`_, edit the
file ``/etc/g-octave.cfg`` and append the lines below (with your data)::
trac_user = username
trac_passwd = password
.. _`create an account`: http://www.g-octave.org/trac/register
.. _`g-Octave project page`: http://www.g-octave.org/trac/
Now you're done with the configuration.
Running the script
------------------
Update the package database::
# g-octave --sync
Make sure that you have activated all the ``USE`` flags needed on octave::
# emerge -vp octave
And build it first::
# emerge octave
Now that you already have the main dependency of the packages installed
and g-Octave configured, you can run the script::
# /usr/share/g-octave/contrib/manage_pkgdb.py
The packages are installed with the ``--oneshot`` option. To remove them
with the dependencies, run::
# emerge -av --depclean
Umounting filesystems/directories
---------------------------------
::
# exit
# cd
# umount /home/user/g-octave/{proc,dev,usr/portage}
