MythTV 0.28 status

tld · Veteran Joined: 09 Dec 2003 Posts: 1816

I was curious as to what experiences anyone here has had with MythTV 0.28. One thing I see is that there's apparently a missing dependency on dev-qt/qtxml that may need to be added:

https://bugs.gentoo.org/show_bug.cgi?id=582218

I'm especially interested in finding out about anyone running it without systemd. I see in the changelog that it includes mythlogserver for non-systemd systems, and I'm curious as to whether that all works out. I'm currently logging just to log files under /var/log/mythtv...no syslog etc.

When I try this I'll probably use my local overlay in any case in order to make the same change I've added to mythtv-0.27.6_p20160318 as described here:

https://bugs.gentoo.org/show_bug.cgi?id=580856

That is, to remove the dev-qt/qtdbus dependency as well as the sys-fs/udisks dependency for dvd support. With that I'm running fine with no udisks or dbus with my DVD device manually set as /dev/sr0.

Thanks in advance for any feedback, and 1000 thanks to the MythTV maintainers! MythTV on Gentoo is the best.

Thanks for all the info! Great to know about mythlogserver. I'd definitely like to avoid that if it's optional.

I think my plan will be to try that from my overlay with:

1. The missing dev-qt/qtxml added,
2. The line to force the mythlogserver USE for non-systemd removed (and -mythlogserver in my USE),
3. The dev-qt/qtdbus and sys-fs/udisks dependencies removed.

I'm sure that udisks is in fact only for finding drives. Again, everything works great in 0.27.6 without it. I think the remaining questions around the dependency in the ebuild are around convenience etc...especially for those who have multiple drives for example.

Thanks again!

I've been getting my ebuild together for the 0.28 upgrade.

I was really stunned with the crap I found out about qtwebkit requiring ruby...and apparently it's just required for the build process(??). Insane.

Was there ever any consensus as to whether or not MythTV even needs qtwebkit at all? Without something like mythbrowser in use I can't imagine why it would. It's hard to be sure, but looking at the configure script it appears to be a hard dependency(??).

Particularly for large projects, it is possible that the configure script marks something as a dependency, but that nothing installed actually uses it. When in doubt, patch the configure test not to access that dependency, uninstall it to be sure it is not used automagically, and try to build the project. If it works, great, you found a bogus dependency. If it fails, the error should give you some hint about how critical or not this dependency is to the overall project. Maybe it is only needed for features you are willing to turn off, or is only used in situations that you can patch out with an acceptable (possibly very small) loss in functionality.

@tld: I just looked and it appears you opened a new topic about this on mythtv-users.
For the benefit of anyone that may find this topic on the Gentoo Forums but not the topic on the mythtv-users, I will quote the first reply here:

Thanks! You beat me to it

. I was going to add that here.

Just to update, there seems to be some disagreement among the devs as to whether qtwebkit is a requirement. I believe it's only required for mythbrowser (?) but I'm not 100% sure.

Another update: qtwebkit is required for MythBrowser, and also MythNews, MythNetVision, and MythMusic use MythBrowser. I've asked if it would be possible to have a configure option to skip qtwebkit assuming you don't plan on installing any of those plugins, and whether or not other code expects, for example, the qtwebkit heads to exist.

All that aside, I went ahead and installed the dependencies (including qtwebket) yesterday using "emerge --oneshot". It took my old systems about 5 to 6 hours to compile qtwebkit...a bit painful.

I just upgraded MythTV today. The only thing I had to change was that I missed the fact that the ebuild needed to have the media-gfx/exiv2 added. Everything went flawlessly after that and things are working great...loving it, and loving the lack of mythlogserver!

A small update to this: Since my last update needed to recompile MythTV and Qt5 due to dependency upgrades, I went ahead an added Qt 5.7.1 to my package.keywords and used that. All working great so far.

Note that I'm not using dbus, and I had to remove the gtk USE flag from dev-qt/qtgui, as 5.7.1 wanted to pull in gtk+3 and dbus with it. That worked as well.

This package is in dire need of a maintainer. If you are interested in helping out to keep this package available in Portage, please consider to step up as a proxy maintainer.

@tld, it seems you are maintaining your own mythtv ebuild, while there is a (yet) masked 0.28 version in tree as well - is there any delta worth reporting?

What this means is that there is no mechanism to disable dbus usage from a build switch. The build system will enable or disable it based on availability at build time - Pacho's link should explain very well why we can not work with that.

mythtv is soon going to be de-stabilised - 0.27 will be simply dropped and 0.28 kept ~arch keyworded.

I have a failed compile of mythtv-0.28.1-r1. I note however that it fails after a section of the code that puzzles me.

Jaglover · Posted: Tue Sep 12, 2017 7:40 pm Post subject:

FWIW, MythTV 29.0 is the current release, I'm considering ditching 0.28. https://www.mythtv.org/wiki/Release_Notes_-_29.0

gcyoung: you misunderstand. A symbolic link can be created in a dangling state, pointing to nothing. This is not very useful, but it is legal. To be useful, the symlink target would need to be brought into existence later, or all consumers of the symlink would need to understand that it is not meant to point to a file. What is the failure you saw?

Thanks Hu. I did not know that. My programming experience is a bit ancient and was with pascal, (and a little lisp) and I think the compiler would have screamed out at anything like that in the past.

My compilation terminated abruptly after the passage I entered (above), with the following, which I have not found to be very informative.

You have to look at the error, you posted the post-error message only. BTW, there will be no 0.29, the new version is 29.0.

For what it's worth, I just recently updated to 0.28.1-r1 successfully. That was on x86. I also have my own ebuild, though it's only modified so as to skip udisks2 and qtDBus. As Jaglover indicated, the pertinent error text will be the first error which will be a ways above what you posted.

I have solved my problem. It seems to have been caused by opengl, which had its flag set from the 'emerging' of earlier versions of mythtv. Examination of the failed code indicated errors around references to opengl. I had noticed earlier that an overall update of the system had called for an update of mesa which I had not been able to do, because of blocking between differing versions of llvm being called for by the system.

Anyway, I deleted opengl from my USE flags, the llvm blocking problem appeared to be solved, and I am now currently executing an update of 52 files which were called for on the omission of opengl -- which I was not aware I still had on the system!

Quotes are normal in English prose, but forum software has better and more descriptive alternatives. Although your actual text didn't benefit from this as much as some posts do, code tags provide value in two ways: they use a monospace font, and they preserve whitespace that would otherwise be collapsed.

In all the posts I've cleaned for missing/incorrect quote/code tags, yours was the first I'd seen somebody mark something with double quotes instead of a bad tag. I didn't have a canned edit for that one.

I was wrong in thinking I had solved my problem with mythtv-0.28.1-r1. Changes I made stopped a block which prevented an update, and I assumed that the continuation of an update would also include the 'emergence' of mythtv. The errors I cannot resolve are as follows:

gcyoung · Posted: Mon Sep 25, 2017 3:22 pm Post subject: Mythtv=0.28.1-r1

I note that the errors I have encountered are identical to those listed on the Mythtv website referred to above. Since I cannot discover any errors in my settings, and I see that the errors were corrected in version -0.28.2 I shall remain with version 0.27 until a later, (amended?) version is available.

Or you try to create a version bump yourself and then submit it on Gentoo's github mirror!
