This is a brand new installation on my HTPC. I upgraded from Mageia One which was working fine. Now, I've tried to reinstall MythTV and when I try to run mythtv-setup (or mythfrontend, or mythbackend) I get a segfault. Even with the -v flag I don't get much info.

Code: Select all

Nothing is showing up in the mythtv logs. Syslog isn't much help:

Oct  5 15:50:39 pvr kernel: [ 3800.198259] mythtv-setup[12914]: segfault at 10 ip b6c49f43 sp bfdefa80 error 4 in libmythbase-0.25.so.0.25.0[b6bbc000+1b0000]

Still trawling Google on this, but I'm not finding much assistance.

Any clues?

Thanks.

Try to run it inside the gdb debugger, install all relevant -debug packages and open up a bug report with the backtrace from gdb: https://wiki.mageia.org/en/Debugging_software_crashes

Done. Thanks.

Actually you should have probably first reported it to Mageia bugzilla: https://wiki.mageia.org/en/How_to_report_a_bug_properly

Hey, I was just following the instructions in gdb.

Okay, I'm off to open an account there and then cut and paste.

So now:

https://bugs.mageia.org/show_bug.cgi?id=7726

there is an updated mythtv in the updates/testing repository which I think you will find resolves your segfault. It has been stuck in testing for some time due to some other unresolved issues.

OKay, as soon as I get the chance (Tuesday?) I'll enable that repo and see if that installs and/or resolves this thing.

Thank you for the tip djennings!

Just got a message from the bug guys. Looks like there is a dup bug and the culprit may be desktop effects. When I get a chance, I'll disable desktop effects and try and run Mythtv-setup again.

Just wanted to get it on the record because it may be Tuesday before I can get to it.

Mark

Okay, I disabled desktop effects and still no joy. Updating the bug and considering downloading the packages in testing.

Mark

I installed the packages from updates/testing and that runs. Still configuring but this one may be resolved.

Thanks for the help guys. I'll know more this weekend.
