Installing MythTV SVN on Fedora
This guide is to help users of Fedora Core to compile MythTV using the Subversion (SVN) source code, to take advantage of the latest (bleeding edge) patches to MythTV.
Overview
This overview assumes you already have MythTV running via the guide at http://wilsonet.com/mythtv/
This guide was developed with MythTV 0.19.1 and Fedora Core 4 in mind. Additions are welcome by users of other Fedora Core versions.
This guide was also built with the help of another wiki page Upgrading To SVN
Install prerequisites
Repositories
You will need the atrpms and freshrpms repositories to be installed. See http://wilsonet.com/mythtv/fcmyth.php#xtrarepos for details on how to do this.
Setup a user called mythtv, and login to it
If you have not done so already, create a separate user called mythtv
# adduser mythtv # passwd mythtv
Remove packages
We need to remove the MythTV packages installed when we followed the MythTV HOWTO. However, this keeps all of the libraries that we need to compile MythTV later.
# rpm -qa | grep myth | xargs rpm -e
Install packages
There are a number of development libraries and packages required to compile MythTV. The following commands should obtain them all.
# yum install lirc-lib-devel lame-devel qt-devel subversion libmyth
Run the following to get the myth plugin dependencies
# yum install fftw2 fftw2-devel libid3tag libid3tag-devel libmad-devel flac-devel libcdaudio-devel SDL-devel cdparanoia-devel libexif-devel fftw3 fftw3-devel
If you get the following error message during the myth plugin dependencies installation:
Error: Missing Dependency: libid3tag = 0.15.0b is needed by package libid3tag-devel
this means that you have a library installed that is greater than the development library available (in this case libid3tag-devel is v0.15.0b but libid3tag 0.15.1-3.b is installed). To resolve this do:
# yum remove libd3tag
then run the above yum install and it should resolve the dependencies correctly.
Install MythTV source code
Now login as the mythtv user you created above.
Here we use subversion to obtain the latest source code.
$ svn co http://svn.mythtv.org/svn/trunk/mythtv $ svn co http://svn.mythtv.org/svn/trunk/mythplugins $ svn co http://svn.mythtv.org/svn/trunk/myththemes
Compile the source code
Compile MythTV
Configure the destination of the package
The first step is to point MythTV to install at /usr/local instead of /usr just in case we already have various MythTV packages installed from using the MythTV Fedora HOWTO previously.
$ cd mythtv $ ./configure --prefix=/usr/local
Note: there are a lot of additional command line options for the configure phase. Here's the full command line I used:
$ ./configure --prefix=/usr/local --enable-xvmc --arch=i686 --enable-proc-opt --enable-dvb
To check them all out use ./configure --help
$ qmake PREFIX=/usr/local mythtv.pro
Start the MythTV compile
$ make
Now install mythtv (you should still be logged in as root to do this):
# su # make install
Now we'll ensure that the mythbackend will start automatically when the PC reboots:
# cd contrib # cp etc.rc.d.init.d.mythbackend /etc/rc.d/init.d/mythbackend # chmod a+x /etc/rc.d/init.d/mythbackend # cp etc.sysconfig.mythbackend /etc/sysconfig/mythbackend # /sbin/chkconfig --level 345 mythbackend on # echo "/usr/local/lib" >> /etc/ld.so.conf # /sbin/ldconfig # exit
Start the MythPlugins compile
$ cd ../mythplugins $ ./configure $ qmake mythplugins.pro $ make
If you receive an error message of something like -lrfftw not found during the compile, you may need to do the following
$ su # cd /usr/lib # ln -s librfftw.so.2.0.7 librfftw.so # ln -s libfftw.so.2.0.7 libfftw.so # exit
then just do a make as before
After the make has completed successfully you need to install the plugins:
$ su # make install
The web-based interface to MythTV (mythtweb) also needs to be installed:
# cd mythweb # mkdir /var/www/html/mythweb # cp -R * /var/www/html/mythweb
Configuration
You are now ready to configure your MythTV system
$ su - # mythtv-setup # service mythbackend start
Applying SVN upgrades
One of the advantages of running SVN is that you can odwnload the latest revision of MythTV. There are usually 5 or more updates a day to the MythTV source code. These guides let you know
What has changed since I last compiled MythTV?
You should subscribe to the mythtv-commits mailing list. FIXME: Details on where to subscribe.
make clean / make distclean
Sometimes when there is an update, there will be a comment in there which says "make clean" or "make distclean". If you need to perform a make distclean, you will lose all of your previous ./configure parameters. It is recommended you keep your own compile parameters in a separate .sh file so you can easily rebuild if you need to perform a make distclean.
Here's a couple of scripts I use to make life easier:
--- doconfig.sh --- cd mythtv make distclean ./configure --prefix=/usr/local --enable-xvmc --arch=i686 --enable-proc-opt --enable-dvb qmake PREFIX=/usr/ocal mythtv.pro cd ../mythplugins make distclean ./configure qmake mythplugins.pro
--- domake.sh --- cd mythtv make -j 2 cd ../mythplugins make -j 2
Updating your source code
Use the same svn commands as shown above to checkout the source trees. SVN is smart enough to download only the files that have been updated.
