Installing MythTV from source on Ubuntu Edgy 6.10

This guide assumes you have installed the base Edgy system (currently Alpha 3 as of this writing) successfully, you have installed accelerated video drivers, and your system is connected to the internet and fully functional. Note that all shell commands, unless otherwise noted, are from the main user's home directory, and are all executed by the main user with sudoer privileges.

Edit /etc/apt/sources.list

Using your favorite text editor, first back up the file /etc/apt/sources.list:

~$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Then, using your favorite text editor with root privileges, open /etc/apt/sources.list and give your system access to dependencies it will need to compile myth (i.e.)

~$ gksudo gedit /etc/apt/sources.list

~$ sudo nano /etc/apt/sources.list

You can just copy and paste the next block of text into your sources.list file...it provided me with a 3D spinny-cube desktop, google earth, and Nintendo 64 on the same box as my backend and one of my front ends runs on:

Save and exit.

[edit]

Update your system, prep the mythtv user, install dependencies, download Myth

Next, update your apt repositories:

~$sudo apt-get update

Update your system:

~$sudo apt-get upgrade

If your kernel was updated, please reboot your system now.

Create the mythtv user:

~$sudo useradd mythtv

You will need to add the mythtv user to some groups to make things work. Do it through your favorite GUI tool or from the shell if you like. mythtv is an account that logs on automatically on my box, and I don't keep national security secrets on this computer (I have those on my direct-from-the-install-CD windows NT-4 Server/IIS4 box with ports 21, 80, 445, and 3389 forwarded to it, with no administrator password!), and physical access is limited to me, my roommate, and my girlfriend, none of which know my password, so I put the mythtv user in a lot of secondary groups to make life easy:

daemon, bin, sys, disk, cdrom, audio, www-data, video, plugdev, games, users, ssh, haldaemon, rich(that's me), admin, mysql

Build dependencies for MythTV:

~$sudo apt-get build-dep mythtv

This should install almost all dependencies to install MythTV, including build-essential. One additional package needs to be downloaded in addition:

~$sudo apt-get install libqt3-mt-mysql

Install MySQL Server:

~$sudo apt-get install mysql-server-5.0

- Optional**

If you plan on using a DVB tuner card, download the kernel headers so you can use them when compiling myth:

~$sudo apt-get install linux-headers-`uname -r`

You may need firmware for DVB or other cards...information that will lead you on the right track can be found here: AVerTV HD A180

Prepare the Shared Libraries:

Edit /etc/ld.so.conf and add:

/usr/local/lib

Now download and extract MythTV:

From GUI, go Here, download, and extract using your favorite decompressor, or

~$wget 'http://mythtv.org/modules.php?name=Downloads&d_op=getit&lid=129'
~$tar xvfj mythtv-0.20.tar.bz2

[edit]

Compiling MythTV

This is where you may need to make some changes depending on your hardware set up. This is for a set up with a DVB tuner card; just delete the last two configure options if you don't need DVB, and change the directory containing the kernel headers (apt-getted above) depending on your version of the linux kernel if you do need DVB:

~$cd mythtv-0.20
~/mythtv-0.20$./configure --prefix=/usr --enable-xvmc --enable-opengl-vsync --enable-proc-opt --dvb-path=/usr/src/linux-headers-2.6.17-8/include/ --enable-dvb

The first option is the most important, as otherwise Myth won't work after installing as it will get put in the wrong directory. Now:

~/mythtv-0.20$qmake mythtv.pro
~/mythtv-0.20$make

[edit]

Installing MythTV

Go have a beer or five, depending on how fast your system is. Return, hopefully with no errors while compiling, and:

~/mythtv-0.20$sudo make install

Now comes the tricky part. First, create the mythconverg database in mysql:

~/mythtv-0.20$cd database
~/mythtv-0.20/database$mysql -u root < mc.sql
~/mythtv-0.20/database$

The lack of verbage, and just a prompt on next line is a good sign that mysql is in fact running, and the database was created successfully.

Next, create a script so mythbackend starts automagically upon system boot and the daemon is started and stopped properly (cd back into your home folder so it looks the same as this: '$cd ~'):

~$sudo nano /etc/init.d/mythbackend

Again, use your favorite text editor to copy and paste this chunk of text into the file, if you don't like nano...

Save and exit. Now make that file executable:

~$sudo chmod +x /etc/init.d/mythbackend

Now add it to startup services:

~$sudo update-rc.d mythbackend defaults

Finishing up

Now, run mythtv-setup and configure your back end, run mythfilldatabase to populate some data into your TV listings, reboot for $h1ts and giggles, then type mythfrontend into a shell, take a really really deep breath, slowly, gently press the enter key, and hope when you go to watch live tv, it actually works. If you have other front ends, or plan to have this as a back end only machine, be sure to edit /etc/mysql/my.cnf (sudo'ed), find this line:

bind-address           = 127.0.0.1

and change it to this:

#bind-address           = 127.0.0.1

There is a wealth of information on what's covered in the Finishing up section here elsewhere in this Wiki, but I did my best to give a thorough walkthrough of what it took to get this running on Edgy.
