I have tried to get this resolved with the mythtv list, but with no luck, so here goes. I am running mythtv 0.16 and have set up the backend and the frontend with no problems. However, when I try to switch to tv, it crashes with the following: ian@minion ~ $ mythfrontend 2004-12-03 15:43:04 mythfrontend version: 0.16.20040906-1 www.mythtv.org 2004-12-03 15:43:04 Enabled verbose msgs : important general 2004-12-03 15:43:05 Registering Internal as a media playback plugin.

CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer" CHOST="i486-pc-linux-gnu" Your cflags and chost might be conflicting. You should change CHOST to "i686-pc-linux-gnu". That way it will jive better with the march=athlon-xp cflag. Also try turning your -O3 down to -O2. I've read in a few places that this combination of settings on an AMD XP can cause bad binaries
Switching to TV, or trying to display any TV output on mine just gives a blank screen and I have to kill X to make it respond - it used to actually display a channel fine, but not respond to key presses, so I couldn't change the channel or exit it without killing X. If I start mythfrontend as any other user besides root, it crashes and then dies, but I've checked all the permissions and it should work. This seems to be the same problem as the original bug reporter (did you have to turn off the lirc flag to get it to compile too? lirc won't emerge for me, and I have other bugs to file for now). Permissions shouldn't kill a program anyway, so I think there is another bug - it should just complain. I'm curious what the directfb use flag does .. I have it on, but don't know what it does .. it doesn't seem to make the frontend use directfb instead of X. Should I turn it off? I also get the following errors on mythfrontend, although it runs - this is a brand new install of Gentoo! mythfrontend: Symbol `_ZTI14BooleanSetting' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI19ConfigurationWizard' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI27TriggeredConfigurationGroup' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI15LineEditSetting' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI12Configurable' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI13SelectSetting' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI19ConfigurationDialog' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI26VerticalConfigurationGroup' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI28HorizontalConfigurationGroup' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI14IntegerSetting' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI7Setting' has different size in shared object, consider re-linking mythfrontend: Symbol `_ZTI18ConfigurationGroup' has different size in shared object, consider re-linking What is messed up here? I also noticed that most themes don't work with myth-tv-0.16, so the myth-themes package shouldn't be installed with newer myth-tv installations (should this be reported as a seperate bug?) CFLAGS="-O2 -march=athlon -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" USE flags: [ebuild R ] media-tv/mythtv-0.16 +X +alsa -arts +cle266* -debug +directfb +dvb +lcd* -lirc +mmx -nls -nvidia +opengl +oss* +xv 0 kB OSS, LCD, and CLE266 I've tried turning all off to see if it improves. It doesn't. I don't think its a CHOST or -O2 vs -O3 issue. I've already got those set as specified since installation. Note: I've intentionally compiled the entire system with the relatively meager set of compilation flags in hope of getting better stability by having fewer software bugs than with possibly other more aggressive sets of optimizations. I haven't found a an improvement yet.
DirectFB doesn't even appear to work upstream. Support for it has been removed from the 0.17. None of the maintainers with CVS access to MythTV can even say if it worked properly in 0.16. Until the upstream code gets fixed, directfb support is out.
The error <<has different size in shared object, consider re-linking>> can be fixed by remergint the package owning the file. See bug 338347 . The issue is not in the app, but in portage 2.2, or in revdep-rebuild.
