[gentoo-user] emerge mythtv fails

[gentoo-user] emerge mythtv fails

[Shawn Haggett]

Some recent updates have broken my mythtv (missing libraries) so I'm of course 
trying to recompile it. Whenever I try however, the following happens:

sgc ~ # emerge -va mythtv

These are the packages that would be merged, in order:

>>>  '/var/tmp/portage/media-tv/mythtv-0.21_p18314-r1/temp/build.log'
sgc ~ #         


The error seems to be in the line: 
/var/tmp/portage/media-tv/mythtv-0.21_p18314-r1/temp/environment: line 3924: 
cd: /var/tmp/portage/media-tv/mythtv-0.21_p18314-r1/work/branches/release-0-21-fixes/mythtv: 
No such file or directory

There's a folder missing somewhere, and when I look, sure enough:

sgc ~ # ls /var/tmp/portage/media-tv/mythtv-0.21_p18314-r1/work/
mythtv-0.21_p18314
sgc ~ #  

It seems the work folder has a 'mythtv-0.21_p18314' folder, which has the 
branches folder inside that.

This has been broken for over a week now (normally I just wait, resync and 
these things go away if they're an ebuild problem) but I'm starting to think 
it's a problem on my end. Anyone have any suggestions on how to track down 
where the error is coming from. It the environment file, but I'm not sure if 
that's a distributed file, or generated by portage (I suspect the later). So 
where does that file get its contents from?

Thanks
Shawn

I just had the same problem with a fresh install of mythtv. I tried other 
versions, 0.21_p19961-r2 showed the same problem, but 0.21_p20877 did 
compile. So give that one a try.

No idea where the exact problem lies, I did not even use mythtv yet. Other 
things to do first.

I don't yet use MythTV myself, but had reason to investigate it again  
this week.

I saw this mentioned on the MythTV-users list (probably a more useful  
resource for you than this list, TBH). Perhaps you may find it useful:

Stroller.

I ran into this same problem approximately two weeks ago on my amd64 box
with the same version. I also needed to rebuild mythtv due to a library
upgrade. I originally thought that the problem arose when the ebuild
switched from using a SVN checkout to a tarball download. However, the
changelog shows that this happened on March 2nd, but I successfully
emerged mythtv-0.21_p18314-r1 on April 24th.

I upgraded mythtv to 0.21_p20877. It builds correctly on my system and
also corrects an issue I was having with the backend process
occasionally segfaulting when the frontend exited. Sorry I do not know
how to fix this particular issue, but so far 0.21_p20877 has been
working great for me on amd64 after a few days of light usage.

Thanks, although I'm already on that list too. I haven't seen this problem 
mentioned on the mythtv-users list (and a quick search doesn't turn anything 
up).

I chose this list to post to, since the problem appears to be a Gentoo/portage 
issue, rather then a mythtv issue. I suspect a bug needs to be filled for 
Gentoo, although I didn't want to needlessly file bugs and annoy the hard 
working bug wrangles/devs.

Now python-updater wants to rebuild mythtv, and fails to do so because of 
the missing version.pro. Same version which built before. The ebuild's date 
is from july 20th, some days before I emerged it, so there was no silent 
change.

Strange. But for the moment I don't care, no time yet to play with mythtv.

BTW, the expected .../work/mythtv-0.21_p20877/version.pro can be found in 
.../work/branches/release-0-21-fixes/mythtv/version.pro.

I've been dealing with this failure for a couple of weeks now. Nothing
new released to address it yet even though it seems there might be
some sort of a fix pending, or even possibly released (as per the last
couple of entries) but for me p20877 still doesn't build:
