Questions:

1) Is this a new install or did it work previously and now doesn't?

2) Have you tried to run mythtv-setup? You don't have to do anything with it--just see if it draws the main window without crashing.

3) Does mythfrontend --version crash?

FYI, you are the first person I know of trying to run this on 10.8.1.

[ctreleaven (Craig Treleaven)]

You could also try starting the frontend with:

mythfrontend -O ThemePainter=opengl

OR

mythfrontend -O ThemePainter=qt

[jharvell@…]

This is a new install.

mythtv-setup does run and opens the main window complaining that the DB schema version on the sever (1306) is newer than expected (1299). In fact today I upgraded mythtv on the Linux machine to an 0.26pre version. Just prior to that the schema version on the server was 1299. mythfrontend crashed on my macbook air the same both before and after this upgrade.

mythfrontend --version does not crash....output below: felicia:~ jharvell$ mythfrontend --version Please attach all output as a file in bug reports. MythTV Version : v0.25.2-46cab935-MacPorts MythTV Branch : fixes/0.25 Network Protocol : 72 Library API : 0.25.20120506-1 QT Version : 4.8.2 Options compiled in:

You cannot mix versions--we only have a 0.25 version on MacPorts so there is no way to work with your server now that it is at 0.26. If you made a pre-upgrade backup (which normally happens automatically), you may be able to downgrade your server. Otherwise, there is little way to debug this further at the moment.

I hope to add a mythtv-core.26 port but haven't done any testing at this point so it will be some time before it is committed.

BTW, 0.26 went to the release candidate stage over a week ago. If you want to go ahead with 0.26, I'd recommend getting up to date. See ​http://www.mythtv.org/wiki/Release_Notes_-_0.26

Yes, but the crash first occurred with the following mythtv backend version:

{code} 2012-08-08 20:52:49.499742 C [3278/3278] thread_unknown mythcommandlineparser.cpp:2534 (ConfigureLogging) - mythbackend version: master [v0.25-rc-106-gf73dbda] www.mythtv.org. In that case the schema was also 1299. {code} So I think the bug report is valid.

I realize this means I have to wait for an 0.26 version from MacPorts or downgrade. I do have a DB backup, but I'm not sure I want to downgrade.

Maybe I could contribute to an 0.26 Mythtv port? I'm relatively new to MacOS, but I've been running Gentoo on my Linux boxes for years. It seems like a port file is conceptually similar to an ebuild. I've also developped C++ on Linux for years.

[ctreleaven (Craig Treleaven)]

Could you please contact me by email (address in port info)? I tried emailing you but it failed with "[HotMail_Bounce] 451-'4.3.5 Server configuration problem' (delivery attempts: 10)".

[serversage@…]

I'm actually seeing the same problem on 3 different macs (installed using port 2.1.2 on each system). Each has Xcode 4.4.1 installed. The versions of QT and mythtv are the same as the OP's. The Macs being used are:

• 2009 Mac Pro running OSX 10.8.1
• 2011 Macbook Pro running OSX 10.8.1
• Mid 2010 Mac Mini running OSX 10.7.4.

The backend is Ubuntu (precise) running mythtv backend 2:0.25.2+fixes.20120828.d519276-0ubuntu0mythbuntu4.

I have tried running mythtv-setup on each Mac, and it starts but I cannot navigate menus unless I run it with -O ThemePainter=qt.

I tried mythfrontend with both theme painter options, but a "Segmentation fault: 11" happens no matter what. I'm more than willing to provide additional info if needed, or to test fixes.

[pixilla (Bradley Giesbrecht)]

Would be nice to have a virtualbox appliance (Ubuntu?) to test the frontend against; configured with a dummy device. Anybody have anything like it?

I had suspected the XCode version but I've now upgraded a 10.7.4 machine to XCode 4.4.1 and mythfrontend appears to work OK (at least accessing mythbackend on the same machine.) Need logs and crash reports to try to narrow down the problem...

• Mid 2010 Mac Mini running OSX 10.7.4.

Also, you might try running the frontend produced from the official packaging system:

There is a version for 10.7 there. I haven't heard any positive or negative reports about it on 10.8.

I've attached the above for the Mac Pro running 10.8.1. I'll have to generate the same for the Mini running 10.7.4 later tonight.

Also, you might try running the frontend produced from the official packaging system:

I actually run the official packages currently on the Mini, which acts as my main frontend. I'm hoping to move to macports for a more automated upgrade path. The official packages are lagging and haven't been updated since back in June.

Replying to serversage@…:

MANY THANKS! Really appreciate the logs and crash reports--I don't have an answer yet but it confirms that the crash happens in virtually the identical spot on different machines running different versions of OS X.

I've requested support from the MythTV devs.

The backend is Ubuntu (precise) running mythtv backend 2:0.25.2+fixes.20120828.d519276-0ubuntu0mythbuntu4.

What version of MySQL are you running? Is the db server on the backend machine, as well?

Please supply the output of mythbackend --version.

Again, thanks for helping to track this down.

[serversage@…]

What version of MySQL are you running? Is the db server on the backend machine, as well?

Version is below, and the db does run on the same server as the backend. Not sure if it helps when looking at the logs, but the IP of my backend server is 10.100.21.2.

mysql --version
mysql  Ver 14.14 Distrib 5.5.24, for debian-linux-gnu (x86_64) using readline 6.2

Please supply the output of mythbackend --version.

And here it is:

Hi, I'm also seeing the signal 11 from Mythfrontend. Running 10.8.1 on a new MBP and on a 10.8.1 Server Mac Mini. This is against a Mythbuntu/Ubuntu backend (is actually a VirtualBox VM running on the Mac Mini, however...). I've also just migrated that Mythbuntu backend to a macports native backend running on the Mac Mini server. The migrated backend works (recording, watching via other mythfrontend), however the macports mythfrontend still fails with the same stack trace.

I'm also seeing Signal 11 crashes in the macports Mythbackend (seems to be coming from the UPNP module service calls). I don't know whether they could be related, but I can provide crash dumps if needed.

Re backend crashes--I believe this would be a separate issue as the backend never calls the code that is crashing in the frontend. Please open a new ticket and attach crash dumps and (portion of) the backend log. Thanks.

This works for me on my 10.7.4 machine, however, I can't (currently) get apple-gcc42 port to install on my 10.8.1 MBP (build fails with wrong architecture errors).

Ok, I got apple-gcc42 installed on my 10.8.1 MBP. Cleaned and configured as above. Subsequent build went fine. Mythfrontend starts and works "as expected", so this does seem to be a viable work-around. As to the root cause...?

I can confirm this works on my 10.8.1 Mac Pro as well. And boy-oh-boy is it ever snappier than the binaries available on source forge. So yes, this is a work-around that seems to work.

Another work around if you are on 10.7 (is 10.8 only 4.4+ ?), is to rollback to Xcode 4.3.3 - this built and ran fine when I tested it earlier today. Seems like something in 4.4.x is making the config/compilation/link go screwy.

If anyone has any suggestions on things to try to get Xcode 4.4 to work, I'll be happy to run test builds.

[jeremyhu (Jeremy Huddleston Sequoia)]

It's been reported via email that using macports-clang-3.0 produces working code and macports-clang-3.1 produces failing code. Please also try macports-clang-3.2.

To use macports-clang-3.2, you will either need base trunk, or you can use configure.compiler=macports-clang after setting 'sudo port select clang' to the 3.2 version.

I just want you to try the 3.2 version to see if the regression has possibly already been addressed upstream.

[ctreleaven (Craig Treleaven)]

Sorry, port select didn't work. After I installed clang-3.2, I tried the following:

MediaMini:~ mytthtv$ port select --list clang
Available versions for clang:
	mp-clang-3.2
	none (active)
MediaMini:~ mytthtv$ port select --set clang mp-clang-3.2
Selecting 'mp-clang-3.2' for 'clang' failed: could not create new link "/opt/local/bin/c-index-test": target "/opt/local/bin/c-index-test-mp-3.2" doesn't exist

DEBUG: action_select [clang mp-clang-3.2] [ports_select_set yes]...
DEBUG: The 'set' command was specified.

MediaMini:~ mytthtv$ port select --list clang
Available versions for clang:
	mp-clang-3.2
	none (active)

Have I done something wrong?

[james.george@…]

A quick summary build testing I've undertaken on 10.7.4:

Xcode 4.4.1 (Clang) = build success, run fail
Xcode 4.4.1 (llvm-gcc-4.2) = build fail
Xcode 4.4.0 (Clang) = build success, run fail
Xcode 4.3.3 (Clang) = build success, run success
Macports Apple-gcc-4.2 = build success, run success
Macports Clang 3.2 = unable to configure (see above)
Macports Clang 3.1 = build success, run failure
Macports Clang 3.0 = build success, run success
Macports llvm-gcc-4.2 = build failure

I will try a build with Xcode 4.5 soon.

[jeremyhu (Jeremy Huddleston Sequoia)]

Cc Me!

[jeremyhu (Jeremy Huddleston Sequoia)]

You need to use sudo when you 'port select' ... please do this to see if the issue still exists in top-of-tree clang/llvm

$ sudo port select clang mp-clang-3.2
$ sudo port -v install mythtv-core.25 configure.compiler=macports-clang

I'm also curious how dragonegg works (since it will use the gcc frontend and llvm backend). This might help narrow down if the issue is clang or llvm. Install dragonegg-3.0 and dragonegg-3.1, then do:

$ sudo port select gcc dragonegg-3.0-gcc46
$ sudo port -v install mythtv-core.25 configure.compiler=macports-gcc

$ sudo port select gcc dragonegg-3.1-gcc46
$ sudo port -v install mythtv-core.25 configure.compiler=macports-gcc

Macports Clang 3.2 is installed. /opt/local/bin/c-index-test-mp-3.2 does not exist. Trying dragonegg's now...

[james.george@…]

Both dragonegg-3.0 and Dragonegg-3.1 fail early in the build process. There are errors about the options (i.e. -arch and -Xarch_x86_64) being passed to gcc.

[james.george@…]

Xcode 4.5 builds successfully but the runtime crashes with the same error as originally detailed in this ticket.

Seems like the build system needs to be updated to not use those flags with macports-gcc

[ctreleaven (Craig Treleaven)]

Thanks, Jeremy,I think we have a winner!

I've successfully built and run myth with Macports Clang 3.2 on 10.7.4. Ala:

MediaMini:mythtv-core.25_rev_3 mytthtv$ sudo port select --list clang
Available versions for clang:
	mp-clang-3.2 (active)
	none
MediaMini:mythtv-core.25_rev_3 mytthtv$ sudo port -d install current configure.compiler=macports-clang

Seems to be running fine. James, could you try the same to confirm?

Jeremy: What should I do with the myth port going forward? This is still a workaround since the user would have to manually do 'sudo port select clang mp-clang-3.2' in order to build successfully.

PS I am using a slightly newer version of Myth. I'm confident none of the code changes account for the fix but that is still why I'd like to see someone else confirm this works for them.

[jeremyhu (Jeremy Huddleston Sequoia)]

That seems to indicate that there is a regression with llvm/clang 3.1 which is fixed in 3.2 ... that's good news, but it doesn't tell us exactly what the change was.

As far as the port is concerned, I'd recommend blacklisting clang from XCode 4.4 and 4.5 and macports-clang-3.1 and falling back on macports-clang-3.0

[james.george@…]

Unfortunately, I have not had any success building with Clang-3.2.

I am going to clean out all my ports and try a fresh install.

[jeremyhu (Jeremy Huddleston Sequoia)]

At quick glance, that seems to have nothing to do with clang-3.2 ...

[james.george@…]

Ok, I got MythTV built with clang-3.2. Yes, it runs without crashing.

I don't know what was in my ports/path/whatever that stopped the build before, but removing all my ports and starting fresh worked. A process that looked something like:

sudo port uninstall installed
sudo port clean all
sudo port install clang-3.2
sudo port configure mythtv-core.25
sudo port clean mythtv-core.25
sudo port select clang mp-clang-3.2
sudo port install mythtv-core.25 configure.compiler=macports-clang

There is probably a simpler process, but this worked for me (and I wasn't bothered as its a test/build machine). :-)

[serversage@…]

I can also confirm that clang-3.2 creates a working MythTV frontend. So I guess that is two possible work arounds.
