<title>Building DEB packages</title>
<para>
In addition to the bootstrap dependencies, you'll also need to install
a few other dependencies by issuing the following commands:
<programlisting><prompt>#</prompt> <command>apt-get</command> update</programlisting>
<programlisting><prompt>$</prompt> <command>apt-get</command> install debhelper openjdk-6-jdk tomcat6 libws-commons-util-java genisoimage python-mysqldb</programlisting>
several other dependencies. Note that we recommend using Maven 3, which
is not currently available in 12.04.1 LTS. So, you'll also need to add a
PPA repository that includes Maven 3. After running the command
<command>add-apt-repository</command>, you will be prompted to continue and
a GPG key will be added.

<command>$ sudo apt-get update</command>

While we have defined, and you have presumably already installed the
bootstrap prerequisites, there are a number of build time prerequisites
that need to be resolved. &PRODUCT; uses maven for dependency resolution.
You can resolve the buildtime depdencies for CloudStack by running the
following command:
<programlisting><prompt>$</prompt> <command>mvn</command> -P deps</programlisting>
</para>
You can resolve the buildtime depdencies for CloudStack by running:</para>

<para>
Now that we have resolved the dependencies we can move on to building &PRODUCT;
and packaging them into DEBs by issuing the following command.
<programlisting><prompt>#</prompt> <command>dpkg-buildpackage</command></programlisting>
</para>
<screen>
<command>$ dpkg-buildpackge -uc -us</command>
</screen>
<para>
This command will build 16 Debian packages. You should have all of the following:

<title>Setting up an APT repo</title>
<para>TBD</para>
<para>After you've created the packages, you'll want to copy them to a system where you can serve the packages over HTTP. You'll create a directory for the packages and then use <code>dpkg-scanpackages</code> to create <filename>Packages.gz</filename>, which holds information about the archive structure. Finally, you'll add the repository to your system(s) so you can install the packages using APT.</para>
<para>The first step is to make sure that you have the <application>dpkg-dev</application> package installed. This should have been installed when you pulled in the <application>debhelper</application> application previously, but if you're generating <filename>Packages.gz</filename> on a different system, be sure that it's installed there as well.</para>
<screen><command>$ sudo apt-get install dpkg-dev</command></screen>
<para>The next step is to copy the DEBs to the directory where they can be served over HTTP. We'll use <filename>/var/www/cloudstack/repo</filename> in the examples, but change the directory to whatever works for you.</para>
<screen>
<command>sudo mkdir -p /var/www/cloudstack/repo/binary</command>
<command>sudo cp *.deb /var/www/cloudstack/repo/binary</command>
<command>sudo cd /var/www/cloudstack/repo/binary</command>
<command>sudo dpkg-scanpackages . /dev/null | tee Packages | gzip -9 &gt; Packages.gz</command>
</screen>
<note><title>Note: Override Files</title>
<para>You can safely ignore the warning about a missing override file.</para>
</note>
<para>Now you should have all of the DEB packages and <filename>Packages.gz</filename> in the <filename>binary</filename> directory and available over HTTP. (You may want to use <command>wget</command> or <command>curl</command> to test this before moving on to the next step.)</para>

<title>Configuring your machines to use the APT repository</title>
<para>
Now that we have created the repository, you need to configure your machine
to make use of the APT repository. We do that by issuing the following commands:
<programlisting><prompt>$</prompt> <command>echo</command> "deb <replaceable>http://url.to/apt/repo</replaceable> $(lsb_release -s -c) 4.0" > <filename>/etc/apt/sources.list.d/cloudstack.list</filename></programlisting>
<programlisting><prompt>#</prompt> <command>apt-get</command> update </programlisting>
</para>
to make use of the APT repository. You can do this by adding a repository file
under <filename>/etc/apt/sources.list.d</filename>. Use your preferred editor to
create <filename>/etc/apt/sources.list.d/cloudstack.list</filename> with this
line:</para>
<programlisting>deb http://<replaceable>server.url</replaceable>/cloudstack/repo binary/</programlisting>
<para>Now that you have the repository info in place, you'll want to run another
update so that APT knows where to find the &PRODUCT; packages.</para>
<screen><command>$ sudo apt-get update</command></screen>
<para>You can now move on to the instructions under Install on Ubuntu.</para>
