[gentoo-user] Old machine update - libexpat upgrade instructions?

[gentoo-user] Old machine update - libexpat upgrade instructions?

[Mark Knecht]

Hi,
   I was updating an old machine overnight that stopped with some
messages inside of a mythtv emerge with issues about qt and libexpat.
I vaguely remember we all had problems with libexpat upgrades a year
ago so I've been searching around for the Gentoo update instructions
but I'm not finding them. Anyone know the right search terms?

Thanks,
Mark

Expat upgrades for versions greater than 2.0 will make some dependencies
break. revdep-rebuild usually solves it with no problems.

Ah. Maybe that's all it is then. I do have 2.0.1 installed nowwhich is
probably an upgrade itself.

Am I correct that revdep-rebuild -p --library=libexpat.so.0 will take
care of finding all the right stuff?

Thanks,
Mark

Even better yet, a plain

    revdep-rebuild -p

will also find other breakages, not only those related to expat. My
update procedure has looked like this for a couple years now (found it
in the forums way back), and I didn't really notice that expat problem
back whenever :-) :

eix-sync
emerge -vDuN world
emerge --depclean
revdep-rebuild -v
etc-update

Pretty much the same here but this is old hardware and a complete
emerge -DuN world would break the machine so until I carefully put
some package masking in place I don't want to do that.

Thanks,

Why? I'm curious about that.

The folks who maintain the portage servers will at times remove old
versions of programs, for instance the ati-drivers package. In that
past I did a blind update and got a new ati-drivers package but
unfortunately it didn't support the ATI 9100 IGP chipset and the
machine broke.

Hope this explains my comment.

Cheers,
Mark

Portage to the rescue!! :-)

Well, eix actually. It comes with a script - eix-test-obsolete - that 
scans your portage config files looking for inconsistencies and 
redundancies, then splits huge amounts of output to the console. One of 
the things it does is find installed ebuilds that are no longer in the 
tree.

This fixes your bind, as you can get copies of those missing ebuilds 
from /var/db/pkg/<category>/<app>/*ebuild and copy them to a local 
private overlay where they will stay for posterity

Alan,
   Thanks. The command is enlightening and is helping me clean things up a bit.

   Now, if I knew anything at all about creating and maintaining my
own overlay I'd be really dangerous. ;-)

Cheers,
Mark

It's easy and very useful. There's even an article on the wiki somewhere 
that tells you how to do it. In summary:

- create a parent directory for the overlay, something 
like /usr/portage/local/mark
- put your ebuilds in there, using the same <category>/<app> structure 
as the main tree
- run 'ebuild /path/to/overlay/ebuild manifest' to create proper 
manifest files
- edit an entry in /etc/make.conf to tell portage to use your overlay
