[gentoo-user] Need for revdep-rebuild

[Peter Humphrey]

Hello list,

Just a note to anyone who hasn't already found out the hard way:

After upgrading icu today I found that system-config-printer-common wouldn't 
compile because it couldn't find the right icu library.

Revdep-rebuild was required to fix this - so it does still have a use, after 
all.

Was any question about that?

I would guess that after about a third of my updates, revdep-rebuild
finds something that needs to be re-emerged.  Sometimes I forget to
run revdep-rebuild, and it's not uncommon that I stumble across
something broken within a day or so.

FWIW, I needed to run revdep-rebuild twice. as one of
evolution-data-server's build dependencies needed icu.  So, if you get
build failures during revdep-rebuild, just keep running it until they
all disappear.

I just had to run preserved-libs and all is well.  I run the unstable 
portage tho.  Maybe that makes a difference.

I always check that sort of thing after a update.  It's just a good 
thing to do and in most cases, it doesn't take to long to do it.

Yes, it does. I seriously can't wait until portage-2.2 is stabilized.

BTW: I couldn't find a tracker bug for its stabilization. Is it possible
that it doesn't exist?

Just one package?  You got off easy.  I shudder when I see an icu update
because my three biggest packages depend on it:  libreoffice, boost, and
webkit-gtk.  The icu update+revdep-rebuild always runs all night (or longer).
My electricity bill goes up that month :(

Wouldn't it be better to do both `emerge @preserved-libs` and `revdep-rebuild`?

I think I read somewhere that `emerge @preserved-libs` and
`revdep-rebuild` actually do different things, but with significant
overlap...

Can't remember where I read that, though...

If it needs you to run preserved-libs it will tell you.  Most of the 
time it will for revdep-rebuild but not always.  It just depends on 
whether or not the dev told it to tell us I guess.

I have no idea what they are waiting on to stabilize portage 2.2.  It 
gets talked about on -dev sometimes but they always leave it unstable.  
I guess they are waiting on the sun to come up in the west or 
something.  lol

And to discover that that was my problem I had to find the stabilisation bug 
for icu-4.8. Not very helpful, I deem.

"Did the Earth move for you?" It certainly would in such an eventuality!

Well, portage 2.2 has been in "testing" for ages.  I been using it for 
ages too and I'm not sure why it needs more testing since it works 
fine.  I seem to have had better luck with the unstable portage than I 
have with a stable.  :/

The earth is always moving.  ;-)
