First, get the v0.21 source from MythTV and unpack it. Next you need to get the development libraries apt-get install build-essential libqt3-mt-dev libmp3lame-dev You need to make sure to install the qt3 development libraries and not the qt4 development libraries. MythTV v0.21 does not support qt4 and will not compile. If you have already installed qt4 development libraries in your system, be sure to apt-get remove libqt4-dev apt-get auto-remove Then you need to configure the source tree. I have to disable dvb because the build will failed with it enabled. . ./configure --disable-dvb --cpu=armv5te If you don't disable dvb, you will get this error message during the build In file included from videosource.cpp:43: dvbtypes.h:23:6: error: #error "DVB driver includes with API version 3 not found!" dvbtypes.h:33:2: warning: #warning DVB API version < 3.1 dvbtypes.h:34:2: warning: #warning ATSC will not be supported using the Linux DVB drivers The error indicates that a proper version of the DVB driver is not installed. I image installing it would fix the problem. Since I do not plan to use DVB, I simply disabled it. After configure, type make; make install I may have forgotten addition libraries that are need. If so, simply search for them with aptitude search <library name> and install the appropriate package. Know that all the necessary libraries to build MythTV are in the repository. Mythtv-setup running on the Sheeva Plug Before you can use MythTV-setup to configure the backend, you need to setup mysql and the mythconverg database. You can follow these instructions to setup the database on the Sheeva Plug. The instructions are for a configuration where the mythconverg database is expected to be accessed remotely. That is likely what you want because you will probably have a separate frontend. Once the database has been installed, type mythtv-setup to setup the backend. Then run mythfilldatabase to fill the mythconverg database. When it is done, you can start the backend with: mythbackend Mythbackend should run and connect to the database. If you want to start the backend automatically each boot, you can use this start up script I took from the Ubuntu distribution. You may have to change line 31: USER=mythtv to whatever user you've used to configure the backend. The script looks for the file ~/.mythtv/mysql.txt that is created during the backend setup. You may also have to edit line 12: DAEMON=/usr/local/bin/mythbackend if mythbackend is not installed in /usr/local/bin. Copy mythtv-backend to /etc/init.d/ and type update-rc.d mythtv-backend defaults Then setup the log directory so that mythbackend has a place to put the logs. mkdir -p /var/log/mythtv chown mythtv /var/log/mythtv If you do not have an user mythtv then replace the second argument of chown with the appropriate username. In my setup, I have a separate slave backend that handles task of recording. This is because: I don't have a USB tuner card, the only tuner card I have is PCI. I found a USB tuner card that has hardware mpeg encoder but it doesn't look like it is supported by Linux yet. So I could not test the recording capabilities of the Sheeva Plug. However, I believe that as long as the driver exists for the USB tuner the backend should record with no problems.
