=========
g-Octave provides a script to run build tests for all the octave-forge
packages. This script is not intended to be used by end-users, only
developers.
.. topic:: Warning!
The automated bug reports are broken right now, because the Trac instance
is currently offline and being moved to the Gentoo Linux infrastructure.
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 ``/usr/portage`` inside the chroot dir::
# 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
# emerge -av mercurial pycurl
Getting the source code
-----------------------
Using the Git repository::
# cd
# git clone git://git.overlays.gentoo.org/proj/g-octave.git
# cd g-octave
Using the source tarball::
# cd
# wget http://files.rafaelmartins.eng.br/distfiles/g-octave/g-octave-<VERSION>.tar.gz
# tar xvzf g-octave-<VERSION>.tar.gz
# cd g-octave-<VERSION>
Configuring g-Octave
--------------------
::
# cp etc/g-octave.cfg /etc
.. topic:: Warning!
This is currently broken!
You should edit the file ``/etc/g-octave.cfg`` and append the lines below
(with your data)::
trac_user = username
trac_passwd = password
For this you'll need to register_ at the `g-Octave project page`_, in order
to be able to create new tickets and attachments.
.. _register: http://g-octave.rafaelmartins.eng.br/register
.. _`g-Octave project page`: http://g-octave.rafaelmartins.eng.br/
Now you need to add the g-octave overlay to the Portage configuration file
``/etc/make.conf`` (use the same overlay path from ``/etc/g-octave.cfg``)::
# echo 'PORTDIR_OVERLAY="/usr/local/portage/g-octave ${PORTDIR_OVERLAY}" >> /etc/make.conf
Running the script
------------------
Update the package database::
# ./scripts/g-octave --sync
Run the test suites::
# ./scripts/run_tests.py
Make sure that you have activated all the ``USE`` flags needed by octave::
# emerge -vp octave
Run the script::
# ./scripts/tinderbox.py
At the end, the script should uninstall all the octave-forge packages
directly installed. If you want to remove the dependencies, run::
# emerge -av --depclean
Umounting filesystems/directories
---------------------------------
::
# exit
# cd
# umount /home/user/g-octave/{proc,dev,usr/portage}
