=====Intro=====
The first effort at completing this with the Pidora Remix had failed.  Here we are going to try and complete this with Raspbian as it is native to the Pi.

====First Steps====
Download the latest Raspian Wheezy and install it onto an SD Card.

Do the Following:
  * Extend the filesystem to take the whole SD card.
  * Disable the GUI (it wont work with the little amount of GPU memory anyway)
  * Set the time and locale settings
  * enable remote SSH
  * enable wait for network on boot
  * Change the user password to something you will remember
  * Change the advanced options:
  * Change the amount of memory for the GPU to 16Mb or less (I did 2mb - more than enough for text).
  * Change the hostname to something you remember.
  * Disable everything not needed such as serial console.
  * Not a silly idea to give it a static IP address either.

The [[pi_kernel_operations|Pi Kernel Operations]] need to be performed before going any futher.

=====Installing Dahdi=====
====Prerequisites====
Install prerequisites needed for the build of dahdi and asterisk:
<code>apt-get install libncurses5-dev bison libssl-dev libnewt-dev zlib1g-dev procps gcc make binutils libusb-dev libasound2-dev alsa-oss libpri-dev</code>
While App_Rpt has been created to use Zaptel, up until Kernel version 3.10, it was able to be modified to compile.  They have taken some legacy routines out of the kernel which means it will not compile without a major overhaul.

Go to the Asterisk website and download the latest version of Dahdi Complete. By using the latest version we have no conflicting problems with the kernel
<code>wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz</code>

Untar the file:
<code>tar -xzvf dahdi-linux-complete-current.tar.gz</code>

Go into the linux folder inside the Dahdi folder and run:
<code>make
make install</code>

Go into the tools folder inside the Dahdi folder and run:
<code>make
make install
make config</code>

now we need to make sure dahdi will run on boot:
<code>update-rc.d dahdi enable</code>

To free up resources from dahdi, edit the /etc/dahdi/modules and # out all the modules (we do not need any of them).

=====Audio Drivers=====
As we do not want to use the onboard audio driver (and to free up more resources), we need to edit /etc/modules:
<code>sudo nano /etc/modules</code>

Edit the file to look like this:
<code># /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

#snd-bcm2835
snd_pcm_oss
snd_mixer_oss
</code>

=====Asterisk-App_rpt=====
====Download====
To download the VKlink version of Asterisk with app_rpt, contact VK3VS via the forum.  This is now required as our version of the software has been modified completely from the original Allstar version.

====Mods to USB radio====
I have modified a version of {{ :chan-usbradio.tar.gz |}} This file could be an old version of the file.

We now need to edit the chan_usbradio.c file.  Remove any occurences of this string: <code>&& !defined(AST_BUILDOPT_LIMEY)</code>  This will make sure that chan_usb compiles correctly under the kernel that the pi runs.
<code>cd ~/asterisk/channels
nano chan_usbradio.c</code>

You also need to add the following includes at the start of the file:
<code>#include <dirent.h>
#include <libgen.h></code>

This goes between //#include <search.h>// and //#include <linux/ppdev.h>// around line 50 or so.

=====Compiling=====
Move into the Asterisk source folder created above. (or trunk/asterisk if using AllStarLink version)

Run the following command: <code>./configure && make menuselect</code>

When the menu appears, make sure you select app_rpt and chan_usbradio.

After selecting all the items you want, save the changes.

edit the makeopts file to change the architecture: <code>nano makeopts</code>

There is a line reading ''PROC=armv6l'' Change this to read ''PROC=arm''.  Otherwise it will fail during compile.

Now run:

<code>make && make install && make config</code>

Asterisk should be installed.

To enable asterisk at boot, go to the contrib/init.d/ folder in the Asterisk build folder and run:
<code>sudo cp rc.debian.asterisk /etc/init.d/asterisk</code>

=====Configs=====
To allow asterisk to start without errors, we need to make some basic config files.  Go to the configs folder in the asterisk build folder, and run:
<code>sudo cp *.conf /etc/asterisk</code>

Then depending on which interface you are going to use, go to that folder, for example usbradio and run the same command:
<code>sudo cp *.conf /etc/asterisk</code>

We now need to make users and groups for Asterisk so it does not run as root
Run the following commands:
<code>echo "asterisk:x:104:104:Asterisk PBX daemon,,,:/var/lib/asterisk:/bin/false" >> /etc/passwd
echo "asterisk:x:104:" >> /etc/group</code>
Now edit /etc/init.d/asterisk and uncomment:

<code>#AST_USER="asterisk"
#AST_GROUP="asterisk"</code>

Since the asterisk user can't write to /var/run (and we don’t want it to) we’ll create a place for it’s process id file. Edit /etc/asterisk/asterisk.conf and change:

<code> astrundir => /var/run</code>

to:

<code> astrundir => /var/run/asterisk</code>

Create the new directory and change the owner to the asterisk users:

<code> mkdir /var/run/asterisk && chown asterisk:asterisk /var/run/asterisk</code>

We also have to fix the file ownship on the rest of the places the asterisk user needs to write to:

<code>chown -R asterisk:asterisk /var/log/asterisk
chown -R asterisk:asterisk /var/spool/asterisk
chown -R asterisk:asterisk /var/lib/asterisk/</code>

You’ll also need to add asterisk to the audio group:

<code> adduser asterisk audio</code>

Reboot the pi and asterisk should magically start.

=====Rpt Sounds=====
you now need to change into the //sounds// folder in the source folder and run the following:
<code>cp * /var/lib/asterisk/sounds</code>
This will copy the required sound file for the repeater application.

=====Tweaks=====
In order to make the DSP work correctly, we need to have a big cleanout go the [[cleaning_up_the_pi|Cleaning Up]] section for more

=====web browser for config=====
Install the packages we need: (this may not be all, but these two will automatically download the rest as dependencies)

<code>sudo apt-get install lighttpd php5-cgi</code>

Enable the fastcgi module and the php configuration with

<code>sudo lighty-enable-mod fastcgi 
sudo lighty-enable-mod fastcgi-php
</code>
Reload the lighttpd daemon

<code>sudo service lighttpd force-reload</code>

To test if it's working create the file /var/www/index.php with the following contents:

<code><?php phpinfo(); ?></code>

and check out [[http://localhost/index.php]] in your browser.
