I've gotten a MythTV addon to build within the OE development system. I've attached the packages used to build MythTV 0.25 and Qt 4.8.1, upon which Myth depends. My starting point for building Qt was the scripts provided by the folks developing
Bino for openelec -- many thanks. I've made changes to that package which means this addon probably can't both be compiled on the same system as the bino addon.
I was able build an ION x86_64 myth package for r10534 on a Debian Squeeze 64bit system. I couldn't get a Generic i386 version to build. I almost certainly broke Qt cross-compilation while trying various things, but then again I can't build Generic i386 OE images either, so YMMV.
So please try building and using this package, but
at your own risk. By which I mean not only that it may delete all your information and set fire to your TV, but that I doubt I will have time to maintain the addon. So even if it works, you risk having an addon that breaks and stays that way if I don't have time to fix it. Hopefully someone else will.
It's surprising that XBMC doesn't have a polished native Myth client. (Yes, I know there's been a lot of work put into
tsp42's libcmyth client, it's still far from the point where I'd turn it over to my wife).
If you previously used the
MythFrontend 0.24.1 addon, and don't have a custom lircrc, you'll need to delete the /storage/.lircrc symlink as the addon location is different. And if sound works in XBMC, but not myth, you may need to set up a dmix device to allow them to share your audio device, as suggested there.
Good luck.
