Hi Jim, Jim Coates wrote: Is there anyway I can try to debug this? I have now tried using CVS with the same result, tried turning on the DEBUG flag in settings.pro and still can't get anything out of gdb. Can you do a strace mythfrontend and send it to me? I think, that you have the same problem as I have. The problem is somewhere in the mysql socket. The first access on this socket works when you watch TV or a record. But the second access results in a segfault on the socket. A few persons had luck with a complete emerge -e world, but this doesn't work for me because I'm running ROCK Linux and I don't want to build a complete new distribution :-(. And of course thats not a real problem solution... For the moment I only can say that I can be a problem of 3 parts. First the problem is cause by MySQL 4.1.x (because 4.0.x worked without segfault). The second problem can be a QT 3.3.3 (I have not tried 3.3.4 which is available in Gentoo already). The third a last possibility is MythTV itself, but then I need a backtrace to debug it (I will do a debug build today from mythtv). I also got a response from Isaac but he said that he cannot do anything without a backtrace.

Re: [mythtv-users] Re: Updated gentoo, now everything mythtv segfaults
The problem is not alleviated by qt 3.3.4 - I run Arch linux and the package didn't help at all. I guess I could try a back version of mysql... ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

masked.

request:
- media-video/dvgrab-1.5 (masked by: ~x86 keyword)
For more information, see MASKED PACKAGES section in the emerge man page or
section 2.2 Software Availability in the Gentoo Handbook.
Result is not OK, you have following choices:
- if emerge failed during build, fix the problems and re-run revdep-rebuild
or
- use -X or --package-names as first argument (try to rebuild package, not
exact
ebuild - ignores SLOT!)
or
- set ACCEPT_KEYWORDS=~your platform and/or /etc/portage/package.unmask
(and remove /root/.revdep-rebuild.5_order to be evaluated again)
or
- modify the above emerge command and run it manually
or
- compile or unmerge unsatisfied packages manually, remove temporary files
and
try again (you can edit package/ebuild list first)
To remove temporary files, please run:
rm /root/.revdep-rebuild*.?_*

For example adding DirectFB will make mythfrontend stop working under X. Also adding things like PAX and other security enhancing (if properly supported by userspace config) kernel patches could trip something in MythTV. Extreme CFLAGS could cause this too.
