h1. Building Quassel core from source on Ubuntu
These instructions tell how to build the latest Quassel core from git for your Ubuntu server or desktop.
Since it scales better with many users and huge amounts of history, setting up PostgreSQL as a backend will be explained as well.
h3. Make sure repositories are up-to-date
<pre>
sudo apt-get update
</pre>
h3. Install required dependencies and build tools
<pre>
sudo apt-get install git-core qt4-dev-tools libqt4-dev libqt4-sql-sqlite screen cmake
* Ubuntu Server Note: use instead:
sudo apt-get -o APT::Install-Recommends=0 -o APT::Install-Suggests=0 install git-core qt4-dev-tools cmake libqt4-dev libqt4-sql-sqlite screen
</pre>
Also install the SQL driver for your planned backend.
- For sqlite (Quassel's default, suggested for single user setups):
<pre>
sudo apt-get install libqt4-sql-sqlite
</pre>
- For PostgreSQL (suggested for multi-user setups):
<pre>
sudo apt-get install libqt4-sql-psql
</pre>
h3. Get the sources
<pre>
mkdir quassel-build
cd quassel-build
git clone https://github.com/quassel/quassel.git
</pre>
h3. Build it
<pre>
mkdir quassel/build
cd quassel/build
cmake -DWANT_CORE=1 -DWANT_QTCLIENT=0 -DWANT_MONO=0 ../
make
sudo make install
</pre>
Another common option to cmake would be:
<pre>
-DINSTALL_PREFIX=/path/where/it/should/be/installed
</pre>
Otherwise /usr/local/ is used as the install prefix.
h2. Optional Step: Use PostgreSQL as backend
h3. Setup PostgreSQL database master user
* "Follow these Ubuntu specific instructions":https://help.ubuntu.com/community/PostgreSQL
h3. Setup quassel PostgreSQL database. The database password will be asked later by the Quassel client configuration wizard.
<pre>
sudo -u postgres psql
postgres=# CREATE USER quassel ENCRYPTED PASSWORD 'somepassword';
CREATE ROLE
postgres=# CREATE DATABASE quassel WITH OWNER quassel ENCODING 'UTF8';
CREATE DATABASE
</pre>
h2. Optional Step: Create SSL certificate:
<pre>
openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout ~/.config/quassel-irc.org/quasselCert.pem -out ~/.config/quassel-irc.org/quasselCert.pem
</pre>
h2. Running Core
"Screen":http://www.debuntu.org/2006/07/04/72-how-to-screen-the-ultimate-admin-tool is a terminal tool which allows you to leave terminal sessions running in the background even when you are logged out.
We run Quassel in screen so that core keeps running as long as it is killed or the server is restarted
<pre>
screen
cd quassel/build
./quasselcore
</pre>
Now you can shut down your terminal and the Quassel core still keeps running.
Later we can reattach to this screen session to check out the Quassel core terminal output to see if there has been any problems. Log in and type:
<pre>
screen -x
</pre>
Now you should how you left your terminal last time you shut it down.
h2. First-time Setup
The configuration wizard will guide you through the rest of the setup when you connect to your Quassel core using a Quassel client for the first time. Remember to choose PostgreSQL backend instead of SQLite when asked.
h2. Start as Daemon
*make install*, create a user *quasselcore* with *quassel* group and create the */etc/init.d/quasselcore*:
<pre>
