Install openerp v6

Last time I was looking for an Erp solution and I tried openerp.
The official installation guide is provided here : http://doc.openerp.com/v6.0/install/linux/
I wanted to install it from source on a basic ubuntu 11.04 machine.
Once more, an incomplete (or not up to date) documentation.

What a time spent by all those users who are looking to make it work, if they were contributing that time to something more usefull... what a wonderfull world would it be...

"I love clear and ready-to-copy-paste documentations !!!"

First thing to know : openerp 6 needs python 2.6 and not python 2.5 since the io module needed by dateutils isn't provided in python 2.5.

Context

Ubuntu server 11.04
Using the root account for convenience.

Database

(install postgress and add openerp user)

apt-get install postgresql
su postgres
createuser --createdb --username postgres --no-createrole --pwprompt openerp

Server installation

Installing dependencies

apt-get install python-lxml python-mako python-egenix-mxdatetime python-dateutil python-psycopg2 python-pychart 
apt-get install python-pydot python-tz python-reportlab python-yaml python-vobject 

Let's add python-setuptools :

apt-get install python-setuptools

Download

wget http://www.openerp.com/download/stable/source/openerp-server-6.0.2.tar.gz
tar -zxf openerp-server-6.0.2.tar.gz

Install, add a specific user and launch the server

cd openerp-server*
python setup.py install
adduser openerp
su openerp
openerp-server

Client installation

Open a new prompt since the server is already logging in the first one.
Dependencies (here python-xml is replaced with python-lxml)

apt-get install python-gtk2 python-glade2 python-matplotlib python-egenix-mxdatetime python-lxml python-tz 
apt-get install python-hippocanvas python-pydot

Download and install

wget http://www.openerp.com/download/stable/source/openerp-client-6.0.2.tar.gz
tar -zxvf openerp-client-6.0.2.tar.gz
cd openerp-client*
python setup.py install

Add symlinks
You have to detect where your client has been installed. I like to use updatedb and locate commands to retrieve the good path. Finally you should get something like this :

/usr/local/lib/python2.7/dist-packages/openerp_client-6.0.2-py2.7.egg/

We have to add symlinks to make our client startup :

mkdir -p /usr/share/pixmaps/
ln -s /usr/local/lib/python2.7/dist-packages/openerp_client-6.0.2-py2.7.egg/share/openerp-client /usr/share/
ln -s /usr/local/lib/python2.7/dist-packages/openerp_client-6.0.2-py2.7.egg/share/pixmaps/openerp-client /usr/share/pixmaps/

openerp-client script
Now we have to correct openerp-client script to let it work:

vim /usr/local/bin/openerp-client
:2,2s/openerp-client/openerp_client-6.0.2-py2.7.egg\/openerp-client/c
:wq

NB : The two last commands are vim specific.

Launch
Now we are ready to launch our client :

openerp-client

Aaah !! Let's learn how it works, that will take much more time, but it will be usefull spent time ... or not ... "what does it meen?" ... no matter ... it's not intended to become a philosophical blog.
