Just an update on my progress:

I was finally able to get a clean build after doing ./configure -- disable-firewire and --disable-xvmc - somehow it wasn't finding either of those even though they were installed (remember I had a completely working myth system with atrpms before) - but when I installed it and rebooted the frontend spit out "your version was compiled with libmyth xxxx while this version is xxxx. You'll have to recompile everything and do a make distclean" (or something similar). Ok. I recompiled and did a distclean before building and the same thing happened.

I then finally decided to restore everything back to where it was - I removed and reinstalled mythtv from atrpms and now I'm back to where I started with no myth lirc working ;)

I've thought about upgrading to CVS - is there a way to know if the lirc bug has been fixed?

Johan,

I sincerely thank you for you help. I'm almost there - I have followed your instructions precisely but I'm having a build error while compiling libmyth. What's weird is ldconfig -p shows libraw1394 stuff linked so I'm not sure what is going on.

/usr/bin/ld: cannot find -lraw1394
collect2: ld returned 1 exit status

Since I posted the original query for help, I've been able to recompile with lirc support.

You have to change a few things for the linker to find the various libraries. I debugged the configure script to see what it was looking for, and then added some to the ldconfig files. Below is the relevant part of my x86_64 build docs, based on Jarod's guide. I should probably post this somewhere, maybe an add on to Jarod's pages ? (It assumes you have yum working; apt doesn't do multi- architecture very well)

My WAF is very high at the moment; I just replaced 2 400-dics cd- changers and 1 vcr/dvd combo with my mythbox over the weekend, and she loves it!

Good luck,

Johan

Building mythtv 0.18.1 from the srpm package.

As the available x86_64 packages did not support lirc, I decided to rebuild from the source rpms to enable lirc support (leaving the already installed packages loaded)

First, install prerequisites for building:

yum install lame-devel
yum install lirc-lib-devel


Now download the source package, and install. This goes to /usr/ src/redhat/SOURCES/.
Here, extract the sources:

tar -jxvf mythtv-0.18.1.tar.bz2

now change into the source directory and configure as needed. I run:
cd mythtv-0.18.1
./configure --prefix=/usr --disable-joystick-menu --enable-lirc -- enable-xvmc

Check the output to make sure all expected things are turned on. -- prefix=/usr sets things to go to the same location as the packages (ie. /usr/bin, /usr/include, etc.), instead of the default /usr/ local, which would result in double copies of the executables.

I noticed that lirc was not being recognized, even though it's installed. Turns out, the configure script looks for two things: the library, and header (.h) files. The header are installed with the lirc-lib-devel package above, but to fix finding the library, I did:

1 - Add file /etc/ld.so.conf.d/lirc-x86_64.conf, containing the line

   /usr/lib64/

2 - now run ldconfig



You're ready to build!  run 'qmake mythtv.pro', then 'make'.

If all builds cleanly, run 'make install' (as root)

Then restart your box (or backend only: "service mythtbackend restart"), and test the new frontend!
