Bugzilla Bug 81767

The latest emerge world pulled in mythtv-0.17 which failed compilation on a
reference to shared library iec61883. However, with USE="-iee1394", mythtv
emerges successfully

Known issue. libiec61883 exists only in a moving SVN repository and isn't in
Portage yet. Waiting for something stable to come from them to be able to add
it to Portage.

Are you capturing over firewire from a cable box? If not you can add into
/etc/portage/package.use the following

media-tv/mythtv : -ieee1394

Is libiec61883 part of ieee1394 or something else? I am willing to make an
ebuild for it.

libiec61883 is Subversion only, hosted by the makers of libieee1394. Which is
why it's not in portage. It apparently hasn't even hit the stabilization point
of 0.1.

Unless you can show me that a snapshot is safe enough... it's going to stay out
of Portage for now.


Eli: Great to see another @ufl.edu e-mail address on here. Comp Engineering or
Comp Sci major?

Doug, if you don't have this lib in portage, then the dependency tree is
broken.  Remove the 'iee1394' USE flag and force it off until this package gets
in portage.

Created an attachment (id=52056) [details]
fixed mythtv ebuild

(From update of attachment 52056 [details])
grrr.. AN EBUILD IS NOT BINARY!!! Don't pick it as such!

Detail what you changed too!

my apologies, I was lazy and told it to autodetect the mime type.  Comment has
now been edited to specify that the ieee1394 use flag has been removed until
the necessary packages are in portage

There's a msg to appease some. But it's staying around until we can get the lib
in Portage.

This will get fixed like I said when the package is available.

A message is insufficient.  Cardoe, this package is in violation of Gentoo
policy.  Either add the package mythtv needs or remove the support from the
mythtv package for now.  Users who have this package on their system can still
add the support via ECONF_EXTRA if they so desire, but as it stands, it is in
violation of Gentoo policy and must be fixed.

if USE=-ieee1394 doesnt work just remove it from the ebuild

I removed ieee1394 from the ebuild and bumped the revision for the dst bugfix.
