revdep-rebuilt fails on kde-base/arts [SOLVED]

[Carlino]

Hello,

it seems that revdep-rebuilt pops many damaged packages, although everything seems fine on my box, (but still, I'm quite puzzled about it), and fails emergeing kde-base/arts ; I know this is because the package has been removed from portage, but then I wonder : what am I supposed to do with the packages that depends on it :

KDE3 was completely removed from portage a while back. You've basically got two choices:
1) Upgrade all of your packages to KDE4 versions and completely rid yourself of KDE3. In this case, if you have a program for which no KDE4 version exists, you'll have remove it. (Other options: find a different package that does the same thing, or bug the program's author to upgrade it to KDE4, then try to find/update/make an ebuild for it.)
2) Install the "kde-sunset" overlay and keep using KDE3 stuff as normal. Note that the kde-sunset overlay is not officially supported.
You should go with the first option if at all possible. KDE3 is no longer being developed upstream, and has no official Gentoo support.

all right MotivatedTea, thanx for the hints : I'm gonna go for the 1st solution then....

I don't know of an easy/automatic way to do that. Someone else might be able to suggest some clever bash commands. When I moved from KDE3 to KDE4, it involved a bit of tedious manual work. I can describe what I did, but you should be prepared to set aside some time to fix problems.

First of all, bring your system fully up-to-date ("emerge -uND world"), and try running "emerge --depclean --ask". (Check the output carefully. "emerge --depclean" could remove something you don't want it to. If it's going to remove too much, then just write down the packages you do want to get rid of and unmerge them yourself.) In a perfect world, that would do everything for you. The only reason it might not be able to do so is if you have a package in "world" that relies on KDE3. That would either be a package that you installed from an overlay, or a package that you installed a while ago that has since been removed from the portage tree.

I have just discovered the "eix" utility (wish I'd known about it a while ago). If you don't already have it installed, emerge app-portage/eix, and then run "eix-update" to update its database. Then run "eix-test-obsolete". That will list a number of things. One of the things it outputs is a list of packages for which ebuilds no longer exist. (eix and its related utilities can tell you all sorts of interesting information about what packages you have installed. See "man eix". You need to run eix-update periodically to update its view of your system.) Since KDE3 was removed from portage, this list should include all of your KDE3 packages. Start by unmerging those.

Another way to try to figure out what KDE3 packages you might have is to run "qlist -IS | grep kde". "qlist -IS" will list all installed (-I) packages with their slots (-S), and then we use grep to filter it for packages with kde in the name. Look for anything that looks like it came from KDE3. I think that would be in slot 3 or maybe 3.5. (I have no KDE3 stuff left on my system, so I can't check that for you.) Note that you have to do some guesswork here, and grepping for "kde" could actually skip some. (For example, app-cdr/k3b is a KDE-based program that doesn't have "kde" in the name. However, at least k3b exists for KDE4.) Try to upgrade those packages to see if they have KDE4 versions. Otherwise, unmerge them. Be careful, though: unmerge just the KDE3 version. By now you probably have both KDE3 and KDE4 versions of many of the common system libraries, and you don't want to get rid of the KDE4 version.

Unmerging packages one by one like this is likely to break things, so you'll need to run revdep-rebuild to fix problems. Since you're running mostly GNOME, this shouldn't cause any major problems for you. (I use KDE, so I did all this at text console.) Also remember that, even if revdep-rebuild gives you an error message about not being able to find ebuilds, you can still manually re-emerge the packages it does manage to identify. Look at /var/cache/revdep-rebuild/5_order.rr and "emerge -1" the packages in there. (Remember to use "-1" to avoid recording them in /var/lib/portage/world.)

Well MotivatedTea, you're teaching me a bunch of useful things, thank you very much; I'm gonna get into the practicing quite soon, and let you know about what's going to turn out of it

So I followed your lead MotivatedTea, and it did work great : my box is up to date, no error no more, everything works fine. Thanx again for the help.
