 Posted: Sat Apr 16, 2005 9:09 pm Post subject: mythtv 0.18 ebuilds |
 |
|
I butchered the 0.17 ebuilds and managed to cobble together some mostly incorrect, sloppy, ugly, but working ebuilds for mythtv and mythplugins. First, mythtv... This worked for me, but I would recommend backing up your database before doing anything rash!
To use these ebuilds, you need to set PORTDIR_OVERLAY in your /etc/make.conf. I set it to /usr/local/portage.
Within /usr/local/portage you will need a media-tv and media-plugins directory. Under media-tv create a mythtv directory and under media-plugins a mythplugins directory. Then cut and paste the following ebuilds into a .ebuild file.
For example:
| Code: | /usr/local/portage/media-tv/mythtv/mythtv-0.18.ebuild
/usr/local/portage/media-plugins/mythplugins/mythplugins-0.18.ebuild |
Once you have the ebuilds in place, do a digest:
| Code: | | ebuild mythtv-0.18.ebuild digest |
and then an emerge:
Good luck!! Please don't use these unless you are willing to give up myth for a bit while it is broke if something goes wrong! And don't hold me responsible should smoke begin pouring out of your computer!

Next, the plugins.....While others may be more enterprising than I, I had no desire to write multiple ebuilds for each different plugin allowing for emerging those you want. This one is all or nothing. I also didn't force the removal of your existing plugins, so if you are going to use this ebuild, unmerge those first. This builds all the plugins with the default settings.

*modified 03/05/05 - updated mythtv-0.18.ebuild with fix for MMX and O3.
There are mythtv-0.18 ebuilds in portage now. However, mmx is hard disabled in them, because of the below bug.
I think I've fixed this now, so a fixed ebuild with MMX use flag and -O3 allowed (with -momit-leaf-frame-pointer filtered as well) is the above attachment on bug https://bugs.gentoo.org/show_bug.cgi?id=87483
I'm using an athlon-xp 2600+ and I get the following error when compiling mythtv ebuild:
| Code: |

|
BTW - if you don't also have the new mythtv themes manually installed, mythfrontend will fail if you have a now missing theme configured - and you can't get into the frontend to change it! I used phpmyadmin to search the mythconverg database for OSDTheme, in the settings table. Delete the row that corresponds to your missing theme for your frontend hostname, and it'll set the theme to the default when you restart mythfrontend.

I've added a new ebuild: mythtv-themes-0.18
Most of the themes from 0.17 have been separated out into a new tarball, which I've added to the old mythtv-themes.
To use the above ebuild, assuming your PORTDIR_OVERLAY=/usr/local/portage in make.conf, copy the mythtv-themes-0.18 ebuild into
| Code: |
/usr/local/portage/x11-themes/mythtv-themes/mythtv-themes-0.18.ebuild
|
and
| Code: |
ebuild mythtv-themes-0.18.ebuild digest
|
then emerge mythtv-themes. You'll also need to have installed a mythtv-0.18 ebuild, (from above) into
| Code: |
/usr/local/portage/media-tv/mythtv/mythtv-0.18.ebuild
|
I've added both the mythtv-0.18 and mythtv-themes-0.18 ebuilds to bugzilla

I've been manually editing the mythtv ebuilds since version 0.16 to include -momit-leaf-frame-point to the filter-flags which will squash the MMX related GENEREAL_REGS errors you mentioned.
| Code: |
# Fix bugs 40964 and 42943.
filter-flags -fforce-addr -fPIC -momit-leaf-frame-pointer
|
Doing this will also make the following "replace-flags" lines unnecessary
| Code: | # fix bug 67832, 81610, etc
#is-flag "-march=pentium4" && replace-flags "-O3" "-O2"
is-flag "-march=pentium4" && replace-flags "-0s" "-O2"
#is-flag "-march=athlon-xp" && replace-flags "-O3" "-O2" |
Which, after commenting out or deleting, will allow the user to make use of O3 optimizations.
Anyway, thanks for the 0.18 ebuild. It worked great for me. |

I just sync'ed and it looks like a lot of the ebuilds are there. Not all, but mythtv, mythtv-themes, mythdvd and mythweb are there.

By the way, if anyone cares, it is possible to compile mythtv-0.18 in portage using the "-momit-leaf-frame-pointer" filter I posted above. From my mytv ebuild log:
| Quote: | # Basic Settings
Compile type release
Compiler cache yes, using ccache symlinked gcc
DistCC no
Install prefix /usr
CPU x86 (Intel(R) Pentium(R) 4 CPU 2.80GHz)
Big Endian no
MMX enabled yes
Vector Builtins no
|
Although I'm no ebuild expert, it seems to work fine. What should I do to help get this enabled in the official gentoo ebuild? Should I post to the myth-0.18 ebuild bug and say "Hey, MMX works fine over here!" or some such?
Edit: I actually created a new attachment to the bugzilla bug posted above. Hopefully the gentoo jocks don't give me a big fat wedgie or a swirly for sticking my nose where it doesn't belong... |

Hi,
I have 2 quick questions regarding the installation of mythfrontend:
1. How can I prevent mythfrontend form installing mysql, as I have it already running on my 'server' on the LAN?
2. Would it be usefull to enable "mysql" as a USE-flag for QT, or can I leave it away?
Thanks for the help  |

| mythfrontend needs the mysql client libraries to function. Thus, what you're asking for isn't feasible. |

I updated to the 0.18 build and I got that timezone bug back now. The first step I did was to upgrade my qt back to the latest version, as I had backsteped to the older qt to fix the timezone but in 0.17. After I did that of course, my mythtv listings where back offset an hour while I waiting for 0.18 to compile.
But now that 0.18 is installed, my listings are still -1 hour off (3am show is listed as being on at 2am). I have gone into mysql and cleared the program data, re-name mythfilldatabase with the same results. I even tried to go into mythtv-setup and set the offset to 'auto', still same result. Is anyone having this problem again? My timezone is set fine and so is my clock.
Oh, and to the poster above me, yes you need the full mysql installed just to use the client.. sucks. |

Umm... this is going to sound like a really stupid question... but is this really the 0.18 build?!!!!
I ask because of two reasons... maybe it's to late and I need some sleep but...
1) timezone bug is still present as far as I can tell, unless I'm missing something here, once I upgraded to 0.18 and brought qt back up to 3.3.4 this should have gone away
2) black screen on return from guide bug is still there. When you go into the on screen guide (think it might only be the PVR-350), and then hit 'exit' to go back to LiveTV, you get a black screen.
These are the 2 big problems I had with 0.17, and they where fixed in the 0.18 release.. and yet.. there are still there. *dazed and confused*
Not to sound rude here, but I'm thinking I'm still using 0.17 and this is all just fake. 
I'm downgrading back to qt-3.3.3 and if my timezone bug goes away... well... then... maybe it won't all be in my head? 
Also, not to nicpick... but in the ebuild, shouldn't the qt line:
be a bit higher of a version? If I understand the timezone bug correctly, you will be needing to user a higher version the 3.3.3 to get the correct time (ie. the 3.3.4).
But then... I'm downgrading to 3.3.3 and need sleep, so don't mind my late-night-fustrated-rambles. |

I updated my linux-headers, renamed my /usr/local/include/mythtv, /usr/lib/mythtv and /usr/include/mythtv to mythtv.old and then the emerge worked. Apparently old headers can cause all sorts of weird compile errors.

I tried this for my problem also... worked... I think.
After downgrading to qt-3.3.3 my timezone bug went away. After I saw your post, I figured I'd try that. I shutdown the mythtvbackend/frontend and removed the directories you said. Then recompiled qt-3.3.4 and mythtv+all my plugins. Now my times are correct again.
The problem with the blank screen after leaving the EPG is still there, but a bit different (the complete fix needs an IVTV update also).
Dunno why, but I'm going to guess I had kind of a mix between 0.17 and 0.18 in there with those headers?
Either way, it's fixed now... YAY! |

Although I'm no ebuild expert, it seems to work fine. What should I do to help get this enabled in the official gentoo ebuild? Should I post to the myth-0.18 ebuild bug and say "Hey, MMX works fine over here!" or some such?
Edit: I actually created a new attachment to the bugzilla bug posted above. Hopefully the gentoo jocks don't give me a big fat wedgie or a swirly for sticking my nose where it doesn't belong... |
Your patch was posted on the orig bug report for the ebuild, I moved it to here:
https://bugs.gentoo.org/show_bug.cgi?id=87483
If your still following this, please make sure I got everything as I edited the current ebuild and and didn't use your own. |

Cool, glad to see there are others who are interested in getting mmx enabled properly in myth. I've been trying to suggest better optimizations for a while now, particularly with mythfrontend where one would would think that it would have the greatest impact with very CPU intensive playback of some videos like HDTV.
Anyway, it looks like you took out the mmx use flag altogether. I don't know if mmx is enabled by default in the myth settings.pro file, I'd have to look, but assuming it is, your ebuild looks great to me. I'll give it a whirl tonight (after the primetime shows are done, of course). Thanks for posting that to the bug report. I hadn't seen that one yet. |

| Uh oh, I did have one big issue with your ebuild, nrdu. It appears that you forgot to retain "myconf=" in the use_enable section thus rendering all use flags such as dvb, nvidia, xvmc, etc disabled. I added a new attachment to the MMX bug. Also, and this is just my opinion mind you, I believe the mmx use flag should remain in place in the ebuild since I believe it's still something the user should be able to enable or disable manually if they want. |

Thanks for looking into that. Still learning about how to make ebuilds so I knew mine was a hack at best. Not to mention I submitted the ebuild about 3 times to bugzilla, once to the wrong bug.
I marked mine as obsolete. 
You should really link to the bug directly next time btw, I was taking kind of a good guess that you had posted it on the orig ebuild from what I had remembered. The link to the attachment is good for a quick download, but it doesn't take into account if the bug is closed, the patch has been updated, etc..
But happy to see you found this, your right about the better optimizations. With your ebuild I was getting about 10fps (if I was lucky) in commflag. With the hack I used, I am getting about 20fps. I'm going to recompile again tonight with this new one you posted, maybe I'll get a bit more. In 0.17 I was getting around 23-26fps.
A lot of people have been complaing about the speed of 0.18, I replied to another post on here, and these is a bit on the mailing list too, all in regards to the ebuild that's in portage. One of the reasons I built my box ontop of Gentoo was to get the most speed I could and the best optimizations. I"m trying to run the whole thing on a Mini-ITX 800mhz box. I'm happy to say, it's very useable (I'm using a PVR-350 for the encode/decode of MPEG-2). |

I have the same problem building plugins so I'll give your suggestion a try. Thanks.

Thank You. That worked like a charm. Now I can have my pluggins back...
