[gentoo-user] dependencies - one more mystery novel

[Helmut Jarausch]

Upgrading to media-libs/jpeg-8
poses a new level of difficulty (to me).

I cannot use  emerge @preserved-rebuild since I still
have kde-3 packages and still have problems with the 
kde-sunset overlay which I have to resolve lateron.

Now, I try to find out which packages depend on jpeg-7.
First idea
revdep-rebuild -p -L /usr/lib64/libjpeg.so.7

but this also finds packages which depend on
 /usr/lib64/libjpeg.so.7 AND /usr/lib64/libjpeg.so.8
probably because they depend on /usr/lib64/libjpeg.so.7
only indirectly.

But how to find out these intermediate libraries which depend
on /usr/lib64/libjpeg.so.7 directly?

Thanks for a hint,
Helmut.

Just run revdep-rebuild without options. It will find and rebuild everything 
that is broken, which is something you need to do anyway. And you need to fix 
that kde overlay as a priority.

Just do it.

The good thing about the @preserved-rebuild system is that it keeps
the old .so until all programs stop needing it. In other words, your
system should continue to function properly and you don't need to be
in a hurry to rebuild those packages that depend on jpeg-7. Once you
fix your KDE problem and have emerge working normally again, then you
can emerge @preserved-rebuild and get rid of dependencies on the old
libjpeg.

I don't know why you wouldn't want to fix the kde3 overlay part ASAP,
but here is a guesswork, which might dig you something useful:

ls /usr/lib64/*.so | xargs -r scanelf -BF%n | grep 'libjpeg\.so\.7' |
awk '{ print $2 }' | xargs -r qfile -qC | uniq

It doesn't understand, e.g., slots, nor is really optimized. For such,
we'd need a separate program, which we'd call ... umm, lemme think ...
is reverse-dependency-rebuilder good? ;)

Not that easy,
revdep-rebuild doesn't work either (dev-db/knoda is missing only in
kde-sunset)

By the way, revdep-rebuild  re-emerges many too many packages,
since it re-emerges all packages which depend only indirectly on
the missing library.
Furthermore the libraries are not missing since the have been kept
by emerge ( => set preserved-rebuild)

Thanks,
Helmut.

First, many thanks for the hint.

Second, kde-sunset poses some difficulties like
!!! Couldn't download 'koffice-1.6.3_p20090204.tar.bz2'. Aborting.

or

kde-misc/kdnssd-avahi
* ERROR: kde-misc/kdnssd-avahi-0.1.2-r1 failed:
 *   net-dns/avahi-0.6.25 does not actually support the qt3 USE flag!


and probably much more to come!

Furthermore, I suspect  emerge @preserved-rebuild
re-emerges many to many packages since most packages
depend only indirectly on libjpeg.so....

Helmut.

Unmerge koffice:2.5 and emerge koffice-meta:3.5.

What is koffice:2.5  ?

emerge --unmerge koffice:2.5
gives
Couldn't find 'null/koffice:2.5' to unmerge

emerge koffice-meta:3.5
fails all over the time :

khelpcneter-3.5.10 : 
x86_64-pc-linux-gnu-g++: ./.libs/libkdeinit_khelpcenter.so: No such file or directory

libkonq-3.5.10 :
/usr/bin/install: cannot stat `.libs/kded_favicons.so': No such file or directory

koffice-libs-1.6.3_p20090204 :
x86_64-pc-linux-gnu-g++: ../../../lib/koproperty/.libs/libkoproperty.so: No such file or directory

So, since GenToo developers have asked to NOT submit bugreports
concerning kde:3.5 I'm lost.
Perhaps I have to wait since koffice-2.2 (kexi is announced again for
that version - Let's hope!)

Thanks,
Helmut.
