Bugzilla Bug 195582

apparently libdca has replaced libdts (libdts blocks libdca) and
mythtv-0.20.2_p14498 fails to build against libdca

Reproducible: Always

Steps to Reproduce:
1.USE="dts"
2.
3.

Actual Results:

removing libdca and installing libdts allows mythtv to build but world update
wants to replace libdts with libdca, after that happens revdep-rebuild wants to
rebuild mythtv but it fails

There's no error visible above, post something more useful please. Also emerge
--info output is required.

Maybe using makeopts j1 instead of j3 shows the problem:

Firstly,

warning: libdts.so.0, needed by /usr/X11R6/lib64/libmythavcodec-0.20.2.so, not
found (try using -rpath or -rpath-link)

What the heck path is that? 

Secondly, it's not attempting to build against libdca, it's using libdts.

If you unmerged libdts or had it on your system, I would run revdep-rebuild

I thought I explained this - emerge update world wants to install libdca,
libdca is blocked by libdts so libdts needs to be removed. If I reinstall
libdts, then the next update attempt will spring the blockage problem again.
If libdts is truly a depend or rdepend (with use=dts) then why doesn't the
mythtv emerge attempt to install libdts after it is removed (and libdca
installed)? Of course if it did this wouldn't work becuase:
==========================================
emerge -pv libdts

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

media-tv/mythtv-0.20.2_p14498 (dts? media-libs/libdca)
media-video/mplayer-1.0_rc2 (dts? media-libs/libdca)

Notice that mythtv is depending on libdca for dts support. Although it wont
compile against it.

wrong.

MythTV will use either libdca or libdts. If you look at the depends it's a
simple or statement. libdca or libdts. Since libdca comes first, it will
attempt to pull that in if you don't have either installed. If you have libdts
installed, then it will happily use that.

But every emerge update world wants to install libdca and triggers the blocking
problem.

The mythtv ebuild has:
dts? ( || ( media-libs/libdca media-libs/libdts ) )
so it should build against either.

The other programs apparently want libdca, and they can't both (libdca and
libdts) be installed at the same time.

The other ebuilds also state either or libdca or libdts, but for some reason
emerge update world wants to replace libdts with libdca.

Did you run revdep-rebuild already?

Yes. It wants to recompile mythtv against libdca. Which fails. The reason this
bug was opened.

Why do you have /usr/X11R6/? It sounds to me like you hand compiled a version
of MythTV not using ebuilds or not using the in Portage ebuilds at some point
and didn't remove that after not using that anymore.

Gentoo hasn't used or had a /usr/X11R6 directory in 2+ years. There's no way a
0.20.2 version of MythTV would use that directory. Since revdep-rebuild didn't
turn up any results, it's 100% the fact that you compiled either direct SVN or
used someone else's ebuilds.

Remove that previous installation and it will be fine. Basically the compile is
attempting to link against that still installed version, which was compiled
against libdts and hence your problem.

Sorry that is not the case. I never installed mythtv outside of a gentoo

Oops, got some extra info in the last post.

I deleted /usr/X11R6 then emerged x11-base/xorg-x11 and the link was

The issue is that -L/usr/X11R6/lib64 is set in there way too early.

It's a bug in the placement of EXTRA_LIBS in mythtranscode/replex/replex.pro,
I've notified the MythTV devs. They will be committing a fix shortly and once
that's done a new ebuild will be added to the tree.

Fixed in mythtv-0.20.2_p14668. You can always unmerge your current version and
re-emerge it as well. Thanks for finding this.

I am having a similar issue .... any suggestions???
